What is cholera?

Cholera is an infection that can cause severe watery diarrhea and vomiting. These can start 12 hours to 5 days after you are infected with the bacteria that cause cholera. The diarrhea and vomiting cause severe dehydration that can lead to death within hours without treatment.

How are cholera bacteria spread?

The bacteria that cause cholera are not usually spread from person to person. A person is infected by coming into contact with an infected person's bowel movement. Infection can happen when a person eats or drinks food or water contaminated with an infected person's bowel movement. The bacteria can still stay in the digestive system for 10 days. This means the bacteria are put back into the environment each time an infected person has a bowel movement. The bacteria can then infect others, repeating the cycle.

How is cholera diagnosed?

Your healthcare provider will examine you and ask about your symptoms. Tell your provider if you recently traveled to a country where cholera is common or has a current outbreak. Tell your provider if you recently ate or drank anything that was contaminated or not cooked properly. A sample of your bowel movement will be tested for the bacteria that can cause cholera. This is the only way to be sure you have cholera.
