Cholera Disease: Cause Symptoms Prevention

What Is Cholera Disease?

The bacterium Vibrio is caused by cholera, and it is a cholera infection of the small intestine. Vibrio cholera produces a toxin called ‘enterotoxin’ which causes the symptoms of cholera disease.

A type of cholera bacteria called the El Tor biotype tends to cause milder disease than the classic biotype.

The disease is of mild or moderate severity in more than 90% of affected people and is difficult to detect clinically from other forms of diarrhea diseases.

Less than 10% of infected persons develop typical cholera with signs of medium or severe dehydration that sometimes lead to death.

The maternal mortality rate without treatment is between 25% and 50%. Cholera is endemic in India and Southeast Asia.

Cholera outbreaks can bad happen in any part of the world where water supplies, sanitation, food safety, and hygiene practices are poor.



Causes Of Cholera Disease

Cholera is caused by bacteria called Vibrio cholera. The fatal effect of the disease is the result of a potent toxin produced in the form of CTX produced by these bacteria in the small intestine. CTX interferes with the average flow of sodium and chloride when it binds to your intestinal walls.

 When bacteria attach to the small intestine wall, your body starts discharging large amounts of water causing diarrhea and rapid loss of fluids and salt. 

 Polluted water supplies constitute the primary source of cholera infection. Not cooked fruits, vegetables, and other foods can in addition contain the bacteria that cause cholera.


NOTE: Cholera is typically not passed through person-to-person contact.



Possible Symptoms Of Cholera Disease

The majority of people exposed to cholera never become ill. In fact, in most cases, it has been seen that you are unexposed to it and you can never know. Once you become infected, you will continue carrying cholera bacteria in your stool for seven to 14 days.

Cholera usually causes mild to moderate diarrhea like other diseases. Specific symptoms will develop in one in ten people infected within two to three days after infection.
