Overview
Choleria is a severe bacterial gastrointestinal, diarrheal disease. In its most severe forms, cholera is one of the most rapidly fatal illnesses known. A healthy person may become hypotensive within an hour of the onset of symptoms and may die within 2-3 hours if no treatment is provided. More commonly, the disease progresses from the first liquid stool to shock in 4-12 hours, with death following in 18 hours to several days without rehydration treatment.[1][2]
History and symptoms
Symptoms include those of general GA tract (stomach) upset and massive watery diarrhea. Symptoms may also include terrible muscle and stomach cramps, vomiting and fever in early stages. In a later stage the diarrhea becomes "rice water stool" (almost clear with flecks of white). Symptoms are caused by massive body fluid loss induced by the enterotoxins that V. cholerae produces. The main enterotoxin, known as cholera toxin, interacts with G proteins and cyclic AMP in the intestinal lining to open ion channels. As ions flow into the intestinal lumen (lining), body fluids (mostly water) flow out of the body due to osmosis leading to massive diarrhea as the fluid is expelled from the body. The body is "tricked" into releasing massive amounts of fluid into the small intestine which shows up in up to 36 liters of liquid diarrhea in a six day period in adults with accompanying massive dehydration.[3] Radical dehydration can bring death within a day through collapse of the circulatory system.
