What is Cholera?
An infectious disease with a severe epidemic is cholera. It is characterised by significant fluid and electrolyte loss, watery diarrhoea, and severe dehydration. It might end fatally.
The bacterium Vibrio cholera is to blame (V. cholera). Despite being easily treatable, cholera is thought to infect between 3 and 5 million people annually and result in over 100,000 fatalities across the globe.
Untreated severe dehydration has a significant mortality rate, particularly in children and babies. Adults who are otherwise healthy can pass away within hours. Those who make a full recovery typically have lifetime immunity against infection.
In the 1800s, cholera was widespread in the United States, but today it is uncommon due to improved hygienic infrastructure and living circumstances.
Only around 1 in 20 cases of cholera are severe, and many infected individuals experience no symptoms. After exposure, symptoms may start to show up anywhere between 12 hours and 5 days later. They can be moderate or asymptomatic or they can be severe.
Typically, they consist of:
- Large amounts of explosive diarrhoea with watery stools that can resemble rice-washing water are frequently referred to as “rice water stools.”
- Leg twitches
A cholera patient may lose up to 20 litres of fluid each day, which can cause severe dehydration and shock. Dehydration symptoms include:
- slack skin
- darkened eyes
- mouth ache
- reduced secretion, such as less perspiration
- rapid heart rate
- reduced blood pressure
- feeling unsteady or lightheaded
- quick loss of weight
Due to poor sanitation and hygiene, cholera germs frequently enter the body through the mouth and contaminate food or drink that has been exposed to human waste.
They can also enter through consuming seafood that is undercooked or uncooked, especially shellfish that are native to estuarine habitats, including oysters and crabs.
Uncleanly handled produce that has been irrigated with tainted water is another frequent source of infection. A single infected victim can pollute all the water for an entire population in areas with severe sanitation problems, such as refugee camps or villages with very few water resources.
Risk factors for cholera
Cholera can possibly affect anyone, but certain things may make you more likely to get it. Additionally raising your risk of developing a severe case are these risk factors:
- unclean surroundings. Poorly maintained areas and areas with tainted water are home to cholera.
- sick family members. Your risk can increase if you have frequent contact with cholerics.
- stomach acid insufficient. Acidic conditions are inhospitable to cholera microorganisms.
- Blood type O. Severe sickness is more common in people with type O blood. This may be due to the fact that CTX causes a higher response in persons with type O blood than in people with other blood types, per a 2016 study.
- Eating raw shellfish. You run a higher risk of getting cholera if you consume shellfish that was harvested from contaminated water.
Nonetheless, even in areas where cholera is endemic, the risk of infection is minimal if you follow good food safety procedures or take preventive steps.
It is common for cholera to spread through food and due to inadequate hygiene. Cholera risk can be decreased with a few easy steps.
It’s crucial to wash your hands to stop the transmission of sickness. It is also critical to follow these precautions when visiting regions where the disease is prevalent:
- Only eat fruit that you have peeled.
- Steer clear of raw fish, salads, and veggies.
- Make sure the dish is cooked through.
- Ensure that the water is boiled or bottled and is safe to drink.
- Avoid eating street food since it can spread diseases like cholera.
Before visiting a place where cholera is a problem, tourists should educate themselves on the disease. If someone experiences symptoms while in a place where the disease is present, such as leg cramps, vomiting, or diarrhoea, they should get medical help right away.
