Can a common diabetes drug could lower COVID risk?

Can a common diabetes drug could lower COVID risk?

Metformin, a common diabetes drug, was tested by researchers to see if it could stop lengthy COVID.

Metformin can cut down lengthy COVID diagnosis by 40%, according to their research. If these results apply to the general population, more research is required.

Long COVID is characterised by continuous health issues that continue even after a COVID-19 diagnosis and cannot be attributed to any other causes.

The duration of symptoms might range from weeks to years. Long COVID has been associated with more than 200 symptoms, from exhaustion and nausea to memory loss, stomach discomfort, and dyspnea or difficulty breathing.

What causes lengthy COVID has been the subject of several different theories. Mechanistic research, however, are still in their early stages. The illness is still in its early stages of development, as are treatments and prevention strategies.

The coronavirus that causes COVID-19, SARS-CoV-2, is currently the greatest strategy to prevent lengthy COVID, according to the Centres for Disease Control and Prevention (CDC). This can be done, for example, by staying current on vaccines.

The quality of life and reduction of long-term handicap among patients could be improved by measures to prevent protracted COVID after contracting COVID-19.

Three widely used medications were recently investigated for their ability to prevent extended COVID.

They discovered that lengthy COVID was considerably less likely to occur in participants taking metformin compared to those taking a placebo. A common diabetes drug called metformin raises insulin sensitivity to reduce blood sugar levels.

Metformin may reduce the occurrence of long-term COVID.

It was a phase 3 randomised clinical trial. 1,126 individuals with COVID-19 symptoms and a positive PCR or antigen test for this viral infection, ranging in age from 30 to 85 years, were enrolled by the researchers.

The patients had either fat or overweight, which increased their likelihood of developing severe COVID even though they were not hospitalised for COVID-19.

The individuals were randomly assigned to one of six groups, each of which received a different dosage of metformin for 14 days, ivermectin for 3 days, fluvoxamine for 14 days, and placebo. Fluvoxamine is used to treat obsessive-compulsive disorder (OCD), and ivermectin is an antiparasitic medication.

For ten months, the subjects were monitored. Throughout the follow-up period, they were questioned multiple times about whether they had obtained a medical provider’s diagnosis of extended COVID.

After 300 days of follow-up, 8.3% of patients overall reported a lengthy COVID diagnosis. Only 6.3% of patients who took metformin, as opposed to 10.4% of those who received a placebo, experienced lengthy COVID.

In comparison to a placebo, ivermectin and fluvoxamine had no effect on the incidence of long-term COVID.

The Safe Drug Metformin Has Proven Antiviral Effects

Based on the knowledge that metformin is safe and has proven anti-inflammatory and antiviral capabilities, the study team pursued it as a potential long-COVID treatment.

Hector Fabio Bonilla, MD, is the co-director of the Stanford Post-Acute COVID-19 Syndrome Clinic and has observed laboratory test outcomes that support metformin’s potential to lessen antiviral and anti-inflammatory activities that can result in thrombosis (when blood clots block blood arteries) and lung harm.

Dr. Bonilla, who is also a clinical associate professor of infectious diseases at Stanford University, adds, “Plus, this drug is relatively safe, with no increased risk of hypoglycemia low blood sugar and no increased risk of lactic acidosis lactic acid buildup related to low oxygen levels.” There is no need to cease taking metformin before surgery because it is safe to take during pregnancy, breastfeeding, and in individuals with renal failure.

Underlying processes

We discussed how metformin may have decreased long COVID risk with Dr. Mark Guido, an endocrinologist from Novant Health Forsyth Endocrine Consultants in Winston Salem, NC, who was not involved in the study.

It is difficult to say because we still don’t fully comprehend extended COVID, but it might be connected to lowering inflammation, he suggested. Additionally, metformin has been demonstrated to potentially lessen severe COVID and to halt the reproduction of the [SARS-CoV-2] virus in a lab setting, both of which may also be involved.

We also discussed how metformin may have decreased long COVID risk with Dr. Daniel Kim, a board-certified family doctor of Medical Offices of Manhattan who was not part in the study.

He concurred that it is still unknown exactly how certain things work. Nevertheless, he added that earlier research suggests that metformin has an antiviral effect by preventing viral multiplication.

Do all people fall within the study’s conclusions?

Dr. Guido responded to a question concerning the study’s limitations by saying, “Since our understanding of long COVID is still evolving, there were no specific diagnostic criteria used to determine who did or did not qualify as having long COVID.”

The trial was also restricted to participants who were overweight or obese and were not currently on metformin. It is unknown if people who are already on metformin for other disorders or who have a normal weight will experience the same effects from metformin,” he added.

The trial was limited to examining the use of metformin to stop long-term COVID during a patient’s initial COVID infection. It is uncertain whether metformin would guard against extended COVID if a patient had previously contracted COVID-19, he continued.

According to Dr. Kim, “It is also unknown if [the results] can be generalized to early outpatient treatment of COVID-19 patients who were previously diagnosed with COVID-19 infection.”

Avoiding prolonged COVID

The results, according to Dr. Guido, could have a significant impact on short COVID prevention.

“Long COVID is turning into a public health emergency. Long-term public health would greatly benefit if it could be successfully decreased by a cheap, well-tolerated, and easily accessible medicine like metformin,” he said.

Dr. Kim concurred that the results are encouraging. He did point out that additional research is required to evaluate whether metformin is as effective for the broader populace.

Bacterial vs. viral conjunctivitis: What is the difference?

Bacterial vs. viral conjunctivitis: What is the difference?

Eye redness, weeping, and discharge are signs of conjunctivitis caused by both bacterial and viral infections. The eyelids may stay together due to a heavier discharge brought on by bacterial conjunctivitis, though. It could also result in eyelid pain and edoema.

Differentiating between bacterial and viral conjunctivitis can be challenging. However, those who develop viral conjunctivitis typically have either experienced a viral disease themselves or have just come into touch with someone who has. This can aid medical professionals in differentiating.

While both types of conjunctivitis can improve on their own, bacterial conjunctivitis may require antibiotic eye drops. Fewer common bacterial conjunctivitis strains can spread quickly and necessitate immediate medical attention.

Viral conjunctivitis

The conjunctiva, a thin membrane lining the inner surface of the eyelids and the white area of the eyeball, becomes inflamed as a result of conjunctivitis, sometimes known as “pink eye,” an eye infection. Conjunctiva serves as a defence against infections and keeps the eye moist.

The conjunctiva itself, however, can occasionally become infected. Doctors refer to the ailment as viral conjunctivitis when a virus is to blame. Viral conjunctivitis can be brought on by a number of viruses.

  • respiratory infections are brought on by the adenovirus
  • Herpes simplex virus (HSV), which can lead to genital herpes or cold sores
  • Virus called varicella-zoster, which causes chickenpox
  • Measles is brought on by the rubeola virus.
  • picornaviruses

The conjunctiva can become infected by a virus, which can then multiply and cause symptoms like:

  • Having red eyes or eyelids
  • scorching and itching
  • tears or a watery sputter
  • the impression of something strange in the sight
  • sensitivity to light

Adenovirus is the most typical cause of viral conjunctivitis. While suffering from a typical cold, some people can get conjunctivitis. The symptoms of a cold typically go away on their own without medical intervention. It could take 14–30 days for viral conjunctivitis to go away.

Bacterial conjunctivitis

When bacteria invade and irritate the conjunctiva, bacterial conjunctivitis develops. This form of conjunctivitis is more likely to affect certain individuals, such as:

  • children
  • older people
  • wearers of contact lenses
  • individuals with compromised immune systems

The most typical bacterial species that cause bacterial conjunctivitis in kids are:

  • the influenza virus
  • pneumococcal streptococcus
  • Catarrhal Moraxella

Staphylococcal bacteria are the most frequent species to cause the disease in adults. These germs can enter the eye via:

  • interaction with an individual suffering from bacterial conjunctivitis
  • touch with items that the affected person has used in the past
  • exposure to respiratory droplets from sneezes or coughs
  • alterations in the conjunctival bacteria

Similar to viral conjunctivitis, bacterial conjunctivitis can also cause the following symptoms:

  • eyelids clump together because to a thick green or yellow discharge
  • edoema of the cornea
  • Painful and swollen eyelids
  • reduced vision

Viral pink eye vs. bacterial pink eye

Viral pink eye can be contracted when someone sneezes or coughs and the droplets come into contact with your eyes, or it can spread from the nose to the eyes.

Pink eye caused by bacteria exists. Usually, the bacteria enters your eyes through your skin or respiratory system. Additionally, bacterial pink eye can develop if you:

  • Use dirty hands to contact your eyes.
  • application of bacteria-contaminated cosmetics
  • sharing private goods with a pink eye sufferer

When an upper respiratory infection, such as a cold (virus) or sore throat, first develops, both types of pink eye frequently follow (virus or bacteria).

The same general signs and symptoms are present in both bacterial and viral pink eye, including:

  • White of the eyes are pink or crimson.
  • tearing
  • itchiness or scratchiness in the eyes
  • swelling
  • burning or annoyance
  • eyelids or lashes that are crusted, especially in the morning
  • fluid coming from the eye

Here are several methods for determining the sort of pink eye you have.

Viral pink eye:

  • typically begins in one eye but can progress to the other
  • begins with a respiratory illness or cold
  • produces ocular discharge due to water

Pink eye due to bacteria:

  • can begin with an ear infection or respiratory infection
  • one or both eyes are affected
  • causes the eyes to clump together and produce a thick discharge (pus).

A sample of the discharge from your eye can be taken by your doctor and sent to a lab for testing to determine whether you have a bacterial or viral infection.

Treating pink eye

The majority of bacterial and viral pink eye illnesses will clear up on their own in a few days to two weeks. In the meanwhile, treat the symptoms as follows:

  • To avoid dryness, use artificial tears or lubricating eye drops. (Eliminate the bottle once your infection has subsided to prevent self-reinfection.)
  • To reduce swelling, apply warm, moist compresses or cold packs to your eye.
  • Use a wet washcloth or tissue to wipe away the discharge from your eyes.

Your doctor may recommend the following medications if your pink eye is more severe:

  • Antiviral medications may be effective in treating viral pink eye brought on by the herpes simplex or varicella-zoster virus.
  • Pink eye caused by germs can be cleared up with the aid of antibiotic eye drops or ointment.

Once pink eye has cleared completely, follow these instructions to prevent reinfection:

  • If you used eye makeup or cosmetic implements while you were afflicted, throw them away.
  • Discard any disposable contact lenses and pink eye treatment you used.
  • Clean and sanitise cases, glasses, and hard contact lenses.

Pink eye prevention

Pink eye spreads quickly. To prevent acquiring or spreading the infection:

  • Use an alcohol-based hand sanitizer or often wash your hands with soap and warm water throughout the day. Before and after using eye drops or inserting contact lenses, wash your hands. If you come into contact with an infected person’s eyes, clothes, or other private items, you should also wash your hands.
  • Avoid rubbing or touching your eyes.
  • Share personal stuff like towels, blankets, pillowcases, cosmetics, and makeup brushes sparingly.
  • After using them, wash your sheets, towels, and washcloths in hot water.
  • Clean your glasses and contact lenses thoroughly.
  • Stay at home from work or school if you have pink eye until your symptoms subside.

Tips to avoid dehydration when dealing with sickness.

Tips to avoid dehydration when dealing with sickness.

What is dehydration?

When you lose more fluid than you consume, you get dehydrated. Even though water makes up over two thirds of our bodies, even a small loss of water can have negative repercussions. In actuality, water is vital to human life and plays a significant role in regular bodily activities.

Humans can’t survive for very long without water, unlike camels, according to physician leader at Banner Urgent Care Daniel Bates, MD. “We constantly need water to support biologic processes and health. It aids in the removal of pollutants, food digestion, and body temperature regulation. You don’t have to lose a lot of weight before your body starts making sacrifices to make up for it.

Signs and symptoms of dehydration

Although vomiting and diarrhoea are frequently regarded as symptoms in and of themselves, the fundamental effect of both is dehydration. The challenging issue is that some dehydration symptoms may differ depending on your age and that you may not realise you’re dehydrated until it’s too late. For children and elderly people in particular, early detection is crucial to prompt treatment and the avoidance of a more serious illness that could be fatal.

Here are some things to watch out for:

For every age group

  • Thirst
  • Dry lips and tongue that feel slimy and sticky
  • dried-up mucous membranes
  • Skin that is less supple or elastic
  • altered blood flow; chilly, pallid hands and feet
  • urine with a deep colour

In children and infants

  • No soiled nappies for more than 12 hours.
  • feverish or warm
  • Several or no tears when sobbing
  • Sunken-looking eyes
  • drowsy or queasy

In adults

  • reduced frequency of urination
  • fatigue or lightheadedness

In elderly

  • recessed eyes
  • bewilderment and vertigo
  • reduced blood pressure

Hydration during sick

A crucial recommendation is always included in doctor’s orders, whether you have the common cold, a virus, or an infection: “Stay hydrated” or “Drink lots of fluids!” There is a cause behind this. Water consumption keeps your body functioning at its best and aids in the removal of pollutants. On the other hand, dehydration can exacerbate symptoms and lengthen the duration of your illness.

One thing you should know before stocking up on fluids is that not all drinks are created equal when it comes to hydrating you.


By far, this advice is the most elementary. But it’s crucial to maintain simplicity. You should drink eight 8-ounce glasses of water every day, whether you’re healthy or not.

Eat some ice.

This is essentially the same advice as tip #1. However, a different method of staying hydrated if you’re feeling heated or want a change is to chew on frozen filtered water.


While you might be tempted to go for your preferred sugary beverage, resist the urge. Avoid sports drinks, sodas, sweet teas, and fruit juices. Fluids high in fructose lack the nutrients and electrolytes your immune system needs, and the sugar in them can make you more prone to inflammation.

Your water can be supplemented with fruit or vitamins.

Try adding fruits, veggies, or flavor-enhanced vitamin supplements if you’re sick of drinking purified water and yearn for a sweet beverage. Lemons, limes, and oranges are examples of citrus fruits that are rich in vitamin C, which is crucial when you’re feeling under the weather. Antioxidants and vitamins are abundant in berries like blueberries, strawberries, and raspberries, which is very beneficial. In addition, fruits and vegetables have natural sugars that can turn water into a tasty beverage.


Caffeine-free teas are your best option if you’re looking for a hot beverage. Teas with tremendous health benefits when you’re sick include mint, chamomile, ginger, and turmeric. The taste can be improved and additional health advantages can be obtained by adding lemon and/or honey.


You can increase the amount of fluids and nutrients in your diet by eating soups. Many soups are rich in vitamins and nutrients, including chicken noodle soup. Additionally, if you have a sore throat or congestion, a warm soup (or hot tea) will help.

Note: Avoid eating canned soups. Many canned soups include a lot of sodium, which can raise blood pressure and cause inflammation. Choose low-sodium soups instead, or prepare your own.

AVOID Liquors.

Correct, put the hot toddy away. Alcohol can make it harder for your body to fight against illness.

Mistakes People Make When They’re Getting Sick

Mistakes People Make When They’re Getting Sick

Anytime, wherever, bacteria and viruses can proliferate close to you. Any illness, from the common cold to a serious viral fever, can be contracted when using public transportation or while working in an air-conditioned environment.

Yes, there are readily available medical facilities to help you get better as soon as possible. However, many of us continue to do several blunders that prolong and occasionally exacerbate our illnesses. To fully heal, though, requires both basic awareness and perseverance.

You want to feel better as soon as possible when you are ill. However, some of your habits can be aggravating your symptoms. So that you can continue on the path to recovery, avoid making these typical cold and flu mistakes.

Here are a few of those mistakes that you need to stop making in order to get well soon:

You make an effort to persist.

Don’t continue with your regular schedule. In order to fight off the cold or flu virus, your body needs energy. Give sleep first priority. Refuse to carry out those arrangements and opt to skip work or school. You’ll prevent the transmission of harmful infections while also assisting your body in healing.

You ignore flu symptoms.

A common cold normally doesn’t require a visit to the doctor. But if you get flu-like symptoms like a high fever, body aches, or weariness, you should contact them. They could administer an antiviral medication like zanamivir or oseltamivir (Tamiflu) to you (Relenza). You can lessen your symptoms and cut the length of your illness if you take one within the first 48 hours after becoming ill by 1-2 days.

You sleep too little.

Your immune system will get weakened if you don’t get enough, making it more difficult for you to fight off the infection. According to one study, persons who get less than 6 hours of sleep every night have a four times higher risk of being ill than those who receive at least 7 hours. So, get a good night’s sleep and nap during the day. Do your symptoms keep you up at night? Run a humidifier to help you breathe easier and use some honey to soothe a nightly cough.

You pester your doctor to prescribe an antibiotic.

Your condition won’t improve with the medication. Only bacteria can be killed by antibiotics, however viruses are what cause colds and the flu. Antibiotic prescriptions are unneeded in about one-third of cases. You may be more susceptible to adverse effects including diarrhoea and allergic reactions as a result. Additionally, it helps fuel the major global health issue of antibiotic resistance. When germs become accustomed to the medications, they stop working.

You don’t consume enough fluids.

It’s harder to gulp down liquids when your throat hurts. However, staying hydrated will help you thin your mucus and relieve congestion. Additionally, it prevents headaches. Make sure you get enough water. Drink a warm beverage, such as herbal tea or broth, for additional comfort. According to research, it can lessen cold symptoms like weariness and sore throats.

You don’t eat meals or snacks.

Even if you don’t feel particularly hungry, you should nonetheless eat something. The immune cells that fight off cold and flu viruses will be fueled by calories and nutrients. As a result, you might recover more quickly. Take a bite of some chicken soup. According to research, this timeless song may help with some of those symptoms.

Your eyes shine.

Smoking causes throat irritation and lung damage. Your cold symptoms may worsen as a result. So stop using vaping devices and cigarettes, and avoid being around those who are smoking.

You become stressed.

The immune system is negatively impacted by a hormone your body produces when you’re stressed. Additionally, it worsens inflammation, which can exacerbate your stuffy nose. If you make an effort to concentrate on unwinding and healing, you might get better more quickly.

Overuse of decongestants.

Decongestants can undoubtedly help you feel better and even sleep better, which may help your cold last less time, according to Dr. Burruss. A nasal decongestant could cause problems if it is used for more than one or two days. Topical decongestant nasal sprays, according to Dr. Anagewa, “may produce rebound or exacerbated congestion when used beyond three days.”

Denying your illness to yourself.

If you’ve always believed that you can recover from a cold by using your mind instead of your body, give it up. Presuming you’re healthy might not prompt you to reduce your activities, which could lead to overexertion, which would exacerbate your symptoms and prolong your recovery. Worse? If you go to work or the gym when unwell, Dr. Tan warns, you’re exposing people to your condition. The best advice is to pay attention to your body and give it the rest it requires. And by all means, stay at home if you have a high fever, nausea, an upset stomach, a persistent cough, or considerable nasal congestion and a runny nose.

How common is chikungunya virus and its symptoms?

How common is chikungunya virus and its symptoms?

Humans become infected with the chikungunya virus through mosquito bites. Fever and joint ache are two symptoms. Although it is rarely fatal, the symptoms can be very bad, very persistent, and very crippling.

More than a fifth of the world’s countries now have cases of what was formerly thought to be a tropical disease. This page will describe the chikungunya virus, including its causes, symptoms, treatments, diagnosis, and prevention measures.

The bite of a female mosquito carrying the chikungunya virus is the main method of transmission. It is generally not thought to be communicable, but in a few rare instances, the virus can be spread by coming into contact with someone who has the infection through their blood.

How is it spread and found?

Chikungunya, which was formerly restricted to Africa and Asia, has rapidly spread since 2004. Today, more than one-third of the world’s population resides in areas at risk for infection. The Americas, Africa, Asia, Europe, and the Caribbean islands, as well as those in the Indian and Pacific oceans, are among these locations.

When a mosquito bites a person, the mosquito bites carry the chikungunya virus. Chikungunya cannot be contracted from another person. However, when a mosquito bites a person who is infected, the virus is spread. To prevent the virus from infecting others, refrain from acquiring further mosquito bites if you have the infection. Avoid travelling as well.

Symptoms of chickungunya

A fever is usually the initial symptom of chikungunya, followed by a rash. Typically, 4 to 8 days after a mosquito bite, an infected person becomes unwell (but the range can be 2 to 12 days).

These signs include:

  • abrupt onset of a fever (typically above 102 degrees F)
  • Joint aches
  • Headache
  • Myalgia
  • Arthritis
  • Conjunctivitis
  • Nausea
  • Vomiting
  • rash with maculopapules (characterized by a flat red area on the skin covered with elevated bumps)

According to the Centers for Disease Control and Prevention, 3 to 28% of chikungunya infections are asymptomatic even though the majority of those who contract the virus exhibit symptoms.

Causes and Risk Factors of Chikungunya

A virus called chikungunya is spread to people by infected mosquitoes. The virus that causes chikungunya (CHIKV) is to blame.

The virus cannot be passed on directly from one sick individual to another. When a mosquito feeds on a person who has the virus circulating in their blood, the sickness is transmitted. Through its bite, the mosquito can acquire the virus and pass it on to another person.

No infants have been discovered to have acquired the chikungunya virus through breastfeeding, according to the CDC. Mosquitoes carrying the Aedes aegypti and Aedes albopictus species are the primary vectors of the chikungunya virus. The mosquitoes that spread the dengue virus are the same ones.

Urban mosquito A. aegypti has been predominantly linked to CHIKV epidemics in Africa and Asia. However, A. albopictus has been introduced as a second important CHIKV spreader since an incident on Réunion in 2005.

A. albopictus has a larger geographic range and can endure in moderate areas. Contrary to A. aegypti, which primarily inhabits tropical and subtropical regions, A key risk factor for chikungunya is the presence of mosquito breeding grounds close to places where people live.

Complications of chikungunya

Possible complications include:

  • Uveitis is an inflammation of the part of the eye’s ocular structure that is between the inner retina and the outer fibrous layer, which is made up of the sclera and cornea.
  • Retinal inflammation is known as retinal retinitis.
  • Heart muscle inflammation is known as myocarditis.
  • Hepatitis is liver inflammation.
  • Kidney inflammation is known as nephritis.
  • Hemorrhage means to bleed.
  • Meningoencephalitis is an inflammation of the brain and surrounding cerebral tissue membranes.
  • Spinal cord inflammation is known as myelitis.
  • Muscle weakness is a hallmark of the rare peripheral nervous system disorder Guillain-Barré syndrome.
  • Loss of function in the cranial nerves is known as cranial nerve palsies.

Diagnosis of chikungunya

Since symptoms of chikungunya are frequently difficult to distinguish from those of other illnesses, only a blood test can provide a conclusive diagnosis.

Dengue fever has a greater fatality rate than chikungunya, which is 0.1 percent, and must be ruled out as soon as possible because to its higher mortality rate of up to 50% if left untreated.

A person with the aforementioned symptoms should see a doctor as soon as feasible if they have recently been to a region where either of these diseases is prevalent.

Treatment of chikungunya

Although the virus is rarely lethal, its symptoms can be very bad and incapacitating. The majority of people get over their fever in a week, but joint pain might last for months. 20% of patients still experience persistent joint discomfort one year afterwards.

Chikungunya is not specifically treatable with medication; instead, doctors advise rest and drinking lots of fluids.

Fever and joint pain can be reduced with over-the-counter drugs. These consist of:

  • naproxen
  • ibuprofen
  • acetaminophen
  • Physiotherapy may be beneficial for aches that remain longer.

Vaccination for chikungunya

Although there is currently no vaccination or antiviral medication available, the illness is often transient and seldom lethal. The goal of medication is to treat the symptoms rather than the underlying problem. Currently, a phase 2 clinical trial of a chikungunya vaccine is being funded by the National Institutes of Health (NIH). As opposed to inactivated or weakened viruses, the vaccine uses so-called virus-like particles (VLPs).

The immunological responses induced by VLP-based vaccinations can resemble those produced by naturally acquired immunity after viral infection. VLPs can’t reproduce themselves and are not contagious. VLP vaccines do not require the use of entire viruses, hence high-level biocontainment facilities are not required for their preparation.

Prevention of Chikungunya

Since mosquito bites are the primary way of chikungunya transmission, avoiding mosquito contact is one of the greatest preventative measures. The following actions can be followed to stave off chikungunya:

  • using DEET (N, N-Diethyl-meta-toluamide) or picaridin-containing insect repellent to skin and clothing.
  • covering one’s entire body with garments.
  • attempting to spend as much time indoors as you can, particularly in the morning and evening.
  • avoiding trips to places where epidemics are happening.
  • It may be useful to use products that contain PMD (p-Menthane-3,8-diol) or oil of lemon eucalyptus.
  • using air conditioning to keep rooms cool prevents mosquitoes from entering.
  • sleeping with a mosquito net over you.
  • utilising pesticide vaporizers and mosquito coils.

Although chikungunya seldom results in death, the symptoms can be debilitating and last for a long time. The secret is avoiding mosquitoes.

How Contagious is Adenovirus and its symptoms?

How Contagious is Adenovirus and its symptoms?

Human adenoviruses are viruses that can lead to a number of conditions, including pneumonia, acute bronchitis, pink eye, the common cold, and other ailments. Mild or severe disease can be brought on by adenoviruses.

However, the Centers for Disease Control and Prevention (CDC) assert that adenovirus-related serious disease is less frequent. Human adenoviruses are viruses that typically affect the upper or lower respiratory tract or the eyes, according to a 2018 review paper.

According to the CDC, adenoviruses can cause a number of diseases, including:

  • the typical cold
  • flu-like signs
  • fever
  • an upset stomach
  • chronic bronchitis
  • pneumonia
  • Pink eye, or conjunctivitis
  • acute gastroenteritis and gastrointestinal tract inflammation

There are 49 different forms of adenovirus that can harm people. However, according to a 2020 article, the majority of adenovirus infections are asymptomatic. In other words, those who contract these viruses might not exhibit any symptoms.

There are numerous adenoviruses that can lead to major outbreaks, according to the CDC. These consist of:

  • three, four, and seven strains of adenovirus, which cause severe respiratory diseases
  • Adenovirus type 14, which also causes severe respiratory infections, is more common in US military personnel.
  • Types 8, 19, 37, 53, and 54 of the adenovirus, which can cause extremely contagious conjunctivitis
  • Adenovirus types 40 and 41, which primarily affect children and cause gastroenteritis

How the adenovirus spreads?

Adenoviruses are common viruses that cause traditional cold-like symptoms that many people get every year.

Adenovirus symptoms typically appear between 2 and 14 days after the initial exposure.

Symptoms of adenovirus infection can include cough, sore throat, bronchitis, diarrhea, pneumonia, and pinkeye. With a healthy immune system, these symptoms are usually mild and pass quickly.

“The adenovirus is typically associated with respiratory infections, as well as gastrointestinal infections,” said Dr. Helena Gutierrez, medical director of the University of Alabama at Birmingham and Children’s Pediatric Liver Transplant Program.

Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, agrees that adenovirus is quite common and is mostly responsible for outbreaks of pinkeye.

“However, there are also a number of papers that show adenovirus, once it gets into a unit that takes care of immunocompromised patients, can cause more serious outbreaks,” Schaffner said. “They frequently result in pneumonia, and in this case, a number of deaths.”

Despite this recent increase in cases of hepatitis, Schaffner doesn’t believe the general public (or those with a healthy immune system) should be overly concerned. Many cases are mild.

Adenovirus, once it enters a facility that cares for immunocompromised patients, however, can also produce more serious outbreaks, according to a number of articles, Schaffner said. They frequently cause pneumonia and, in this instance, several fatalities.

Schaffner thinks the general public (or those with a healthy immune system) shouldn’t be overly concerned despite the recent rise in hepatitis cases. Many cases are minor ones.

Symptoms of Adenovirus

Various adenovirus types can have different effects on you:

  • Cough, runny nose, fever, chills, and bronchitis
  • Colds and other respiratory infections: Swollen glands, runny and stuffy nose, cough, sore throat, and
  • Coughing up bark, having trouble breathing, and making a high-pitched noise when you breathe in
  • Ear infection: fever, irritability, and ear pain
  • Red eyes, discharge from the eyes, crying, and the sensation that something is in your eye are all symptoms of pink eye (conjunctivitis).
  • Pneumonia: fever, cough, and breathing difficulties
  • Infections of the stomach and intestines: nausea, vomiting, headaches, fever, and cramping in the stomach
  • Meningitis and encephalitis can cause swelling of the brain and spinal cord.
  • nausea, vomiting, stiff neck, fever, and headache (this is rare)
  • Urinary tract infections: frequent urination, burning and pain, and blood in the urine

Consult your child’s paediatrician if you suspect one of these viruses may be present in them. If a baby under three months old exhibits signs of an adenovirus infection, always call the doctor.

If your child exhibits any of these more severe signs, call the doctor right away:

  • difficulty breathing
  • eyes are swollen around them
  • a fever that persists for several days
  • Dehydration symptoms, such as fewer tears or fewer wet diapers

Are adenoviruses contagious?

Adenoviruses spread easily. They can quickly spread by:

  • Close contact: Hand shaking, kissing, and hugging are all ways that the virus can pass from one person to another.
  • Sneezing and coughing can spread the infection through the air. Sneezes, coughs, and other respiratory discharges can spread to other people through the air.
  • Objects and surfaces: If you don’t immediately wash your hands after touching a contaminated surface, the virus can enter your body through contact with your eyes, nose, or mouth.
  • The virus can spread through an infected person’s poop (stool). As an illustration, changing your baby’s diaper can expose you to an infection.
  • Water: Water that has not been chlorine-treated can help transmit the infection. For instance, if an adenovirus-infected individual swims in a pool without enough chlorine, they can spread the infection. Though uncommon, this kind of spread does exist.

Adenoviruses are immune to a variety of widely used disinfectants. As a result, they can spread disease for a very long time on surfaces.

Furthermore, even after you have recovered from an infection, these viruses can continue to release from your body (shed) for days or even weeks. So even if you are symptom-free, the virus can still spread.

Treatment of Adenovirus

Since antibiotics primarily treat bacterial infections, they cannot treat viral infections. Within a few days, children frequently recover on their own from illnesses. Some diseases, such as pneumonia or pink eye, can persist for a week or longer.

Children with a weakened immune system could require hospital care to aid in their recovery.

To assist your child in feeling better, you can:

  • Drink a lot of liquids. Children lose fluids due to diarrhoea, vomiting, and fever. Dehydration is a possibility. For kids to stay hydrated, water or 100% fruit juice are the best options. You might also give an electrolyte-containing children’s solution a shot.
  • Eliminate congestion Help your child to frequently blow their nose. Put a few drops of saline spray or drops into the nostril of an infant. Mucus should then be removed using a bulb syringe.
  • Turn on a humidifier with cool mist. Your child’s breathing will be made easier thanks to the moisture.
  • lower the fever. To reduce pain and a fever, ask your doctor if you can give your kid acetaminophen (Tylenol) or ibuprofen (Motrin).
  • Avoid giving children aspirin-containing goods because they may cause Reye syndrome, an uncommon but deadly illness.

Prevention of adenovirus

Making sure that both adults and kids frequently wash their hands is a simple preventative strategy. The best practise is to wash your hands:

  • during and after the cooking process
  • prior to eating
  • touching someone who is vomiting or having diarrhoea both before and after
  • cutting and wound care before and after
  • following a bathroom visit
  • after a diaper change or after assisting someone to the restroom
  • after sneezing, coughing, or blowing one’s nose
  • Upon contact with any animal, animal products, or animal waste (such as soiled cat litter),
  • after handling any trash

If someone has conjunctivitis, they should also refrain from sharing towels or pillows. This is done to stop individuals of the same home from contracting the adenovirus.

Explore the causes and complications of Hepatitis E virus.

A contagious virus called hepatitis E affects the liver and damages and inflames it. This could eventually result in severe consequences in some persons. Hepatitis E is typically easy to treat, and many patients do not require medical intervention.

Hepatitis E is more frequent than individuals might think, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). The virus will infect roughly 20% of Americans at some time in their lives, according to recent studies. Areas with limited access to clean water might have a higher prevalence of it.

It can spread in a number of ways, but the most frequent ones are through contaminated water and undercooked meat. Hepatitis E symptoms can differ, although they can occasionally be severe. The best defence against hepatitis E is prevention.

Symptoms of hepatitis E

Following HEV exposure, the incubation period lasts between two and ten weeks, on average between five and six. The virus is excreted by the infected individuals from a few days before to 3–4 weeks after the commencement of the illness.

Young adults between the ages of 15 and 40 are most frequently infected with symptoms in regions with high disease endemicity. Although infections do affect children in these places, they frequently go misdiagnosed because they frequently show no symptoms or simply a minor illness without jaundice.

The following are typical hepatitis signs and symptoms:

  • an initial stage characterised by a brief period of mild fever, reduced appetite (anorexia), nausea, and vomiting;
  • joint discomfort, skin rash, itching, or stomach ache;
  • A slightly enlarged, painful liver, black urine, and pale faeces are all symptoms of jaundice (a yellowing of the skin) (hepatomegaly).

These symptoms typically last 1-6 weeks and are often difficult to distinguish from those brought on by other liver disorders.

Rarely, acute hepatitis E can become fulminant and be extremely severe (acute liver failure). These patients run the risk of passing away. Hepatitis E in pregnancy increases the risk of severe liver failure, foetal loss, and mortality, especially in the second and third trimesters. If they contract hepatitis E during the third trimester, up to 20–25% of pregnant women risk dying.

Immunosuppressed individuals, particularly organ transplant recipients using immunosuppressive medications, have been found to have cases of persistent genotype 3 or genotype 4 HEV infection. These are still rare.

What causes hepatitis E?

The majority of hepatitis E cases are brought on by consuming water that has been tainted by faeces. You have a higher risk if you reside in or travel to unsanitary nations. This is especially true in locations that are crowded.

Hepatitis E can also, albeit rarely, be spread through the consumption of animal products. Additionally, blood transfusions can result in its transmission. The virus can potentially infect a pregnant mother and spread to the foetus.

After a few weeks, most infections resolve on their own. The virus also results in liver failure in some cases.

Complications and risk of hepatitis E

Though uncommon, complications are possible. This is especially true for vulnerable populations. The possibility of developing a persistent form of the infection, neurological diseases, severe liver damage, or even deadly liver failure, are all complications.

One significant at-risk population is women who are pregnant. Both the parent and maybe the unborn child might be impacted by hepatitis E. According to the World Health Organization (WHO), the virus has a death incidence of up to 20–25% among pregnant women in the third trimester.

Additionally, those with a history of chronic liver illness or liver disorders may be more at risk for developing hepatitis E. Immunosuppressive medication users who additionally have a liver transplant may potentially be more vulnerable to problems.

Diagnosis of hepatitis E

Hepatitis E cannot currently be diagnosed using any officially recognised test. Doctors must rely on tests to detect the antibodies that fight the virus in order to correctly diagnose hepatitis E. They will also examine the blood for hepatitis A, B, and C, among other hepatitis strains.

Doctors may conclude that a patient has the illness if they test negative for various types of hepatitis but also have the antibodies needed to combat hepatitis E in their body.

Treatment of hepatitis E

Hepatitis E rarely requires medical attention, as the body naturally gets rid of the virus. However, medical professionals could suggest a few measures to help the body while it is fighting the illness.

These consist of:

  • eating a nutritious, diversified diet
  • consuming a lot of liquids, particularly water
  • resting
  • avoiding things like alcohol that irritate the liver

Additionally, doctors might inquire about any medications that a patient is taking. The liver may be harmed by some.

While a patient is recovering from the infection, doctors may examine a patient’s drug regimen to determine whether it can be reduced or stopped altogether. The same is true for numerous vitamins and supplements.

As the body heals, it’s also crucial for patients to visit their doctor frequently. In order to establish whether the body can combat the illness, the doctor may use blood tests to monitor treatment progress or examine for any physical changes.

Doctors may occasionally recommend drugs to treat hepatitis E. People who have an infection that is particularly severe may experience this more frequently. Rarely, a person could need to be hospitalised. Hepatitis E infections that manifest in members of at-risk groups may be one of these situations.

Prevention from hepatitis E

The best method to avoid contracting hepatitis E and any potential problems is to prevent it. Make sure to only consume cleaned water when visiting underdeveloped nations or busy places with dirty water. The simplest method to achieve this is to always drink bottled water.

All water use in these locations must follow the same rules. Use bottled water for all purposes, including food preparation, fruit and vegetable cleaning, and tooth brushing.

The virus will be rendered inactive by boiling or chlorinating water, according to the Centers for Disease Control and Prevention (CDC). Those who are worried about catching the illness might also want to stay away from wild game like deer and raw meats like pork.

No vaccination in the United States has received official approval, as the CDC points out. However, a vaccination was authorised for use in China in 2012 there.

It’s also crucial to stop the virus from spreading. Even though it is rare for the virus to spread between people, anyone who has it should be careful and practise good cleanliness. These consist of, for instance, washing one’s hands with warm water after using the restroom and before preparing food.

What is the maturity period of infection called Norovirus?

What is the maturity period of infection called Norovirus?

The stomach and intestinal virus known as norovirus is extremely contagious. Direct or indirect contact with an infected person is all that is necessary for it to spread. In crowded places like hospitals, schools, and daycare facilities, it can spread swiftly.

The majority of people have some knowledge with norovirus. It affects the stomach and digestive tract frequently. Since the norovirus can be acquired from consuming tainted food, it can potentially cause food poisoning. Regardless of how you obtain it, the outcomes remain the same.

Vomiting and watery, non-bloody diarrhoea are the norovirus’s signature signs and symptoms. These symptoms might appear anywhere between 12 and 48 hours after exposure and continue up to three days. The majority of patients fully recover.

There is no specific therapy other than rest and rehydration. Dehydration is the most important problem. The norovirus can be dangerous and even fatal in extremely young children, elderly people, and those who already have other health issues.

There are numerous norovirus strains, so having one doesn’t shield you from contracting it again. By washing your hands thoroughly and regularly, you can reduce the chance of spreading disease.

With 685 million cases worldwide each year, norovirus is estimated to be the most common cause of acute gastroenteritis. Gastroenteritis is an infection and inflammation of the gastrointestinal tract brought on by any infectious agent, such as bacteria or viruses. Up to 21 million infections are brought on by norovirus each year in the United States.

How contagious is Norovirus?

The virus can remain shed for up to 8 weeks. This indicates that there is a possibility that you could harm other people. Over time, it normally becomes less contagious.

Once you have been symptom-free for 48 hours, you can often go back to work or school. Workers in the food service industry are typically advised to wait 72 hours before handling food.

Norovirus causes

When you come into contact with the virus, everything begins. It can be hiding on the food you eat. Or perhaps you grip someone’s hand or touch a contaminated light switch before touching your mouth or nose. Those minute particles enter your body at that point.

As the particles go down your oesophagus, you are unaware of it. They enter your intestines after passing through your stomach. The intestines are where noroviruses thrive and appear to reproduce quickly. Your immune system is alerted to the existence of outside intruders in the interim. To eliminate them, it orders an army of antibodies.

Within one to three days, your antibodies will often declare victory over the infection. However, the virus may continue to leave your body for up to two weeks or more.

Symptoms of Norovirus

After being exposed to the virus, symptoms of infection typically appear somewhere between 12 and 48 hours later. They might be modest to really severe. Norovirus symptoms include, among others:

  • nauseous and dizzy
  • abdominal discomfort or cramps
  • diarrhoea
  • minimal fever
  • chills
  • headache
  • widespread body pain

The typical duration of symptoms is 24 to 72 hours. If symptoms continue after that or if you notice blood in your faeces, consult a doctor. Dehydration brought on by severe diarrhoea needs to be treated as a medical emergency. Dehydration symptoms and signs include:

  • throat and mouth are dry
  • reduced urine production or dark urine
  • newborns shouldn’t have a damp diaper for 6–8 hours.
  • no urine for children in 12 hours
  • darkened eyes
  • drowsiness and exhaustion
  • headache
  • dizziness
  • uncertainty and sluggishness
  • quick heartbeat

When a child sobs but doesn’t actually cry, they are likely severely dehydrated. Seek immediate medical attention. They may also appear picky and agitated.

Dehydration poses a serious risk to life, particularly for the following populations:

  • individuals with compromised immune systems
  • individuals with current medical conditions
  • the elderly and the young
  • beneficiaries of organ or stem cell transplants

According to estimates, the virus may occasionally—roughly 30% of the time—cause no symptoms at all. Children are particularly prone to this.

Norovirus maturity period

You most likely won’t be aware that you have a norovirus until after contact. You can catch it via eating contaminated food or from contacting a contaminated surface. It can also be acquired through interpersonal interactions. You can easily transfer it from your hands to your lips once they are clean.

The incubation period, also known as the interval between first encounter and the onset of symptoms, typically lasts between 12 to 48 hours, with 33 hours serving as the median.

Nausea could be your first indication that something is wrong. Watery diarrhoea, stomach pain, and sudden vomiting are possible side effects. If done within 48 to 72 hours of the onset of symptoms, the virus can be detected in a sample of your faeces, if necessary. Norovirus can occasionally be found in stool for up to 14 days or more.

You can spread the virus to others as long as it is still present in your stool. Given that the virus only needs a minimal amount to induce disease, doing so is simple. Even if you don’t have any symptoms, you can still spread the infection to other people.

Lets observe Risky symptoms and complication of Monkeypox.

Lets observe Risky symptoms and complication of Monkeypox.

What Is Monkeypox?

A viral illness called monkey pox is comparable to smallpox. It results in a rash resembling a lesion, lymph node swelling, and fever. Your genitals, anus, and other regions may experience the lesions.

An additional zoonotic disease is monkeypox. This implies that it can spread from animals to people and vice versa. Additionally, it can spread from person to person. The West African virus and the Congo Basin virus are the two forms of monkeypox viruses.

Prior to 2022, central and western Africa was where monkeypox was most prevalent. However, as at the time of this article’s publication, cases of monkeypox brought on by the West African variant of the virus had been reported in 94 countries worldwide, including regions where it is not normally found.

How does the mpox virus spread?

MPX is brought on by the MPX virus. Close contact with an infected animal or person allows the virus to spread. Furthermore, it can spread when someone touches objects, such blankets, that have come into contact with an mpox patient.

People can contract the mpox virus through:

  • direct touch with the bodily fluids, scabs, or rashes of a person who has mpox.
  • prolonged close proximity to respiratory droplets from an infected person for more than four hours. This covers having sexual relations.
  • clothing, bedding, blankets, or other items that have come into contact with an infected person’s body fluids or rashes.
  • The mpox virus can infect a pregnant individual and then infect the foetus.

A person contracts mpox from an animal through:

  • Bites or scrapes from animals Wild
  • cultivated wild wildlife used for food
  • Items manufactured from diseased animals
  • direct exposure to the bodily fluids or rashes of animals that have the MPOV virus

Where is Mpox found?

The majority of mpox cases for many years were in Africa. It does, however, occasionally appear in other nations, such as the United States. The United States experienced the first mpox outbreak outside of Africa in the spring of 2003. Texas received a consignment from Ghana with diseased animals. The virus was transmitted by the sick rodents to domesticated prairie dogs, which ultimately infected 47 people in the Midwest.

Viruses that were formerly largely confined to certain regions can more easily spread worldwide as international travel becomes more widespread. A case of mpox was discovered in a resident of the United States who had come to the country from Nigeria in the summer of 2021. Then, in 2022, outbreaks spread beyond of Africa to areas in Europe, Australia, and the Americas.

Anyone can purchase mpox. The majority of cases in Africa involve children under the age of 15. The disease appears to be more prevalent in guys who have intercourse with men outside of Africa, although there are many cases in people who don’t fit that description.

Monkeypox symptoms

Monkeypox symptoms are comparable to smallpox symptoms. Typically, monkeypox symptoms are less severe. Symptoms of the monkeypox virus typically take 6 to 13 days to manifest after infection. But it might be anything between 5 and 21 days.

Early warning signs can include:

  • The most common first sign is a fever.
  • headache
  • muscular pain
  • back pain
  • fatigue
  • chills
  • Lymphadenopathy, another name for enlarged lymph nodes,

A rash often emerges 1 to 3 days after the fever does. Usually, the rash appears on your:

Before or after a fever and other flu-like symptoms, a rash may appear. Some individuals might only ever have a rash. Lesions that develop in the following order make up the rash brought on by monkeypox:

  • flat, brownish blemishes known as macules
  • papules, which are mildly elevated lesions
  • lumps or vesicles filled with a clear fluid
  • lumps or pustules with a yellowish fluid
  • scabs

The lesions scab over and fall off once they have healed. Monkeypox symptoms often last 2 to 4 weeks and go away on their own without medical intervention.

Potential complications of monkeypox

The following are potential side effects of monkeypox:

  • bronchopneumonia
  • sepsis
  • Encephalitis, another name for inflammation of the brain,
  • inflammation of the cornea, the eye’s transparent outer layer
  • further infections
  • Loss of eyesight may result from an infection in the cornea.

In extreme circumstances, the lesions may combine. A significant amount of skin loss could result from this.

How is monkeypox treated?

Currently, there is no cure for monkeypox. Monkeypox, on the other hand, has a self-limiting nature and can heal on its own. There are several drugs that can be used to contain an outbreak and stop the illness from spreading. They may consist of:

  • Influenza vaccine (smallpox vaccine)
  • Immune globulin against vaccinia
  • antibiotics for viruses (in animals)
  • Smallpox is treated with the antiviral tecovirimat (TPOXX).
  • Antiviral brincidofovir (Tembexa), used to treat both adult and child smallpox

Cidofovir, which is normally applied to treat cytomegalovirus-induced eye infections but has also been applied in some instances of monkeypox

With the use of over-the-counter or prescription medications like painkillers, topical creams, and oral antihistamines, other treatments aim to manage symptoms.

What are the threatening symptoms & treatment of Smallpox?

What are the threatening symptoms & treatment of Smallpox?

What is Smallpox?

The virus that causes smallpox is very contagious, fatal, and has no known treatment. This disease has been totally eradicated thanks to global immunisation campaigns; the last reported case occurred in the United States in 1949. Variola is another name for smallpox.

One of the most deadly diseases to affect people since ancient Egypt has been smallpox. Our history books are full of smallpox epidemics that spread far and resulted in significant death tolls.

In 1758, the first smallpox vaccine was developed. However, the illness persisted for an additional 200 years, infecting and killing a lot of people. To reduce the risk of infection, the World Health Organization (WHO) put in place a stringent vaccine requirement.

Does smallpox still exist?

The only contagious disease that people have successfully eradicated is smallpox. The variola virus is still present in a few safe labs, but they are the only known surviving samples. The variola virus does not exist among humans. The first successful vaccine in the history of the globe helped people eradicate smallpox.

A British physician by the name of Edward Jenner noticed that milkmaids who had already had cowpox did not develop smallpox at the end of the 18th century. He concluded from this that exposure to the milder orthopoxvirus that causes cowpox could shield people from the more serious illness.

Although he developed the first vaccination in 1796, it took a while before people started using it. Many people feared the vaccine and lacked confidence in its safety. However, as time went on, researchers enhanced the vaccination, and people became more accustomed to this preventative measure.

Instead of utilising cowpox as the viral agent in this form of inoculation, researchers began employing an orthopoxvirus known as vaccinia in 1900. The World Health Organization (WHO) began a global campaign of mass vaccinations in 1959 in an effort to end the illness.

Smallpox was last reported in a natural setting in 1977, and the WHO declared it extinct in 1980.

Types of Smallpox

Smallpox came in two common and two uncommon varieties. Variola minor and variola major were the names for the two prevalent forms.

Smallpox with variola minor had a lower mortality rate. Only 1% of people who contracted the disease, according to the Centers for Disease Control and Prevention (CDC), perished. It was less frequent than variola major however.

According to the CDC, variola major caused 90 percent of smallpox cases. Historically, 30% of persons who contracted this kind of smallpox died. Hemorrhagic and malignant smallpox were the two uncommon subtypes. These two extremely uncommon types of smallpox had a very high death rate.

Organs began to leak blood into the skin and mucous membranes as a result of hemorrhagic smallpox. Lesions from malignant smallpox did not grow into pustules or lumps with pus on the skin. Instead, throughout the entire illness, they stayed flat and squishy.

How Do You Catch Smallpox?

The fact that smallpox is an airborne illness is one of the reasons it was so deadly and hazardous. Airborne illnesses frequently spread quickly.

The smallpox virus can be spread through coughing, sneezing, or direct contact with any bodily fluids. Sharing contaminated beds or clothing could also spread an infection.

Symptoms of Smallpox

According to historical records, a person with smallpox did not exhibit any symptoms for seven to 17 days after contracting the virus. The following flu-like symptoms manifested after the incubation period (or virus development phase), though:

Two to three days would pass before these symptoms disappeared. The patient will feel better after that. A rash would, however, develop just as the patient’s condition began to improve. The rash first appeared on the face, then moved to the hands, forearms, and major body area. The individual would be extremely contagious until the rash cleared up.

The rash will turn into pus- and fluid-filled abscesses two days after it first appeared. The abscesses would scab up after breaking open. The pit mark scars would gradually fall off the scabs. The person was infectious up until the scabs came off.

Treatment for Smallpox

The smallpox virus cannot be cured. The variola virus (smallpox) has been fully eliminated as a result of extensive, repetitive vaccination campaigns conducted worldwide. The only individuals thought to be at danger for contracting smallpox are scientists who work with it in a lab setting.

Vaccination within one to three days of exposure to the smallpox virus can lessen the severity of the sickness in the unusual case that it does arise. Additionally, medications can lessen the bacterial infections brought on by the virus.
