Many consider cholera as the most severe form of gastroenteritis. Why do you think this is so?
The "stomach flu" is a term used to describe diarrhea and vomiting. Gastroenteritis, a common cause of these symptoms, is to blame.
The stomach and intestines become inflamed and irritated during gastroenteritis. A viral or bacterial illness is usually the culprit.
Vibrio cholerae is the bacteria that causes cholera. A toxin produced by bacteria in the small intestine causes the disease's fatal effects. The toxin causes a huge amount of water to be secreted by the body, resulting in diarrhea and rapid fluid and salt loss (electrolytes).
Hence, cholera is considered as the most severe form of gastroenteritis.
