Question

Cholera bacteria causes sever diarrhoea. These bacteria spread rapidly when sewage is not piped away. Why is this?​

Answer 1

Because cholera bacteria rapidly multiplies in areas with improper sanitation and untreated water that people can drink.

When people drink this water, they get severe diarrhoea.

Answer 2

A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).
