Cholera

Cholera (also called Asiatic cholera) is an infectious disease, caused by bacteria that are typically ingested by drinking water that is contaminated by improper sanitation, or by eating improperly cooked fish, especially shellfish. Symptoms include diarrhoea, abdominal cramps, nausea, vomiting, and dehydration. Death is generally due to the dehydration caused by the illness. When cholera is left untreated, it generally has a high death rate. Treatment is typically an aggressive rehydration treatment. With treatment, death rates plummet. Cholera was first described in a scientific manner by the physician Garcia de Orta in the 16th century.
