Cholera is a severe, dehydrating illness caused by a bacterial infection of the intestine.

Cholera is found in many parts of the world, particularly in Africa.

Cholera is caused by the bacterium Vibrio cholerae.

The bacterium is found in water and soil and can contaminate food or drink.

Cholera can also be spread through contact with contaminated food, such as eating raw or undercooked shellfish.

Cholera can also be spread through contact with contaminated feces, such as when there is poor sanitation.

Cholera can be prevented by practicing good hygiene, including washing hands and cooking food properly.

Cholera can be treated with rehydration therapy, which replaces the fluids lost through vomiting and diarrhea. Cholera can be fatal if left untreated.

Cholera is most common in Africa, particularly in sub-Saharan Africa. Cholera is also common in South Asia, Southeast Asia, and Latin America.

Cholera is less common in developed countries, such as the United States.
