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.

What is chickenpox?

Chickenpox is a very contagious infection caused by the varicella-zoster virus. It mainly affects kids, but adults can get it, too. The telltale sign of chickenpox is a super-itchy skin rash with red blisters. Over the course of several days, the blisters pop and start to leak. Then they crust and scab over before finally healing.

Symptoms appear within 10 to 21 days after you’ve been in contact with someone who has the virus. Most people recover in about 2 weeks. Chickenpox is generally mild, especially in children. But in severe cases, the blisters can spread to your nose, mouth, eyes, and even genitals.

Multiple chickenpox infections are extremely uncommon. Additionally, cases have decreased since the mid-1990s, when the chickenpox vaccine was launched.

A child who has chickenpox can readily infect other kids with the illness. Due to widespread childhood vaccination, chickenpox is much less common today. Before the first chickenpox vaccine was authorised in the United States in 1995, practically everyone contracted the disease. There weren’t many complications.

How is chickenpox spread?

Any age child can contract chicken pox. Your youngster may seem well for one to three weeks after exposure to the chickenpox before developing symptoms. From the day before symptoms occur until around five days after a skin rash appears, children can spread the virus.

The following methods are:

  • interacting with a chickenpox-infected person
  • receiving airborne infection from a sick individual who sneezes or coughs.
  • obtaining bodily fluids from an infected child’s mouth, nose, or eyes.

Difference between smallpox and chickenpox

Both smallpox and chickenpox cause skin rashes, yet they are two distinct diseases. One reason is that smallpox is a far more deadly illness that can be fatal. They are brought on by many viruses.

Even while the two diseases both cause rashes, the rashes themselves appear differently and develop at different times. As opposed to the chickenpox rash, which appears in waves, smallpox pustules are identical to one another. The individual spots don’t all have the same appearance, and while some blister, others form scabs.

There is yet another significant distinction. Smallpox has been eradicated (wiped out) thanks to a large global vaccination campaign.

Symptoms of Chickenpox

The chickenpox rash, which is characterised by itchy blisters and typically lasts five to ten days, occurs 10 to 21 days following virus exposure. One to two days prior to the rash, there may also be additional symptoms and indicators, such as:

  • Fever
  • reduced appetite
  • Headache
  • fatigue as well as a general sick feeling (malaise)

The chickenpox rash progresses through three stages after it appears:

  • Papules, which are raised pink or red pimples that appear over several days
  • Vesicles are little, fluid-filled blisters that develop in a day or so before breaking and leaking.
  • The damaged blisters are covered in crusts and scabs, which take many additional days to cure.

You could experience all three stages of the rash—bumps, blisters, and scabbed lesions—at the same time since new bumps keep developing for several days. Before the rash shows, the virus can be transmitted to other persons for up to 48 hours, and it can still be transmitted until all broken blisters have crusted over.

In healthy children, the condition is typically not severe. Lesions may develop in the mouth, eyes, mucous membranes of the urethra, anus, and vagina, and the rash may cover the entire body in severe cases.

Who is at risk of developing the chicken pox?

Risk is lowered by prior active infection with the virus or immunisation. A mother’s immunity to the virus might be passed on to her newborn. From birth, immunity lasts roughly three months.

The virus can infect someone who hasn’t been exposed to it. Risk rises in any of the following circumstances:

  • recently interacted with a sick person.
  • younger than 12 years old.
  • an adult who shares a home with kids.
  • visited a school or child care centre.
  • your immune system has been damaged by your condition or drugs.

Possible complications of Chickenpox

Call your physician immediately if:

  • Your eyes start to develop a rash.
  • The rash is extremely heated, painful, and red (signs of a secondary bacterial infection).
  • Shortness of breath or dizziness accompany the rash.

When difficulties arise, they typically have an impact on:

  • infants
  • older people
  • those with compromised immune systems
  • expecting mothers

These people may also develop bacterial infections of the skin, joints, or bones or VZV pneumonia. Pregnant women who are exposed may give birth to infants who have birth abnormalities like:

  • bad growth
  • limited head size
  • eye issues
  • intelligence impairments
