Cholera is caused by a bacteria that attacks the lining of the colon. There are really two main reasons so many people die from this disease. One is that the onset of the disease is extremely fast, so there isn't always adequate time to obtain treatment. Death can occur in one or two days. The second is that the disease frequently occurs after flooding or other natural disasters in impoverished areas. This means that medication (antibiotics), clinics, doctors are frequently not available or accessable.
