Causes of Cholera

Cholera is caused by the bacterium Vibrio cholerae.

The causative organism of cholera is a bacterium called Vibrio cholerae. Cholera is transmitted by drinking water or eating food contaminated with the cholera bacterium.

Raw or under cooked seafood may be a source of infection in areas where cholera is prevalent Floodwaters can carry V. cholerae and contaminate drinking water supplies.

The disease is not likely to spread directly from one person to another; therefore, casual contact with an infected person is not a risk for becoming ill with cholera.

After the organisms are taken into the body, they pass the acid barrier of the stomach and begin to multiply in the alkaline environment of the small intestine. The bacteria attach themselves to the microvilli of the epithelial cells of the intestinal tract where they multiply and produce a potent ‘enterotoxin’ known as ‘cholera toxin’. Cholera toxin is responsible for increased secretion of water and electrolytes in stools from the intestines leading to dehydration, shock, acidosis and death.

In Zimbabwe the National Water Authority is failing to supply water to large parts of the urban areas. This has resulted in residences drawing on Boerhole Water and others purchasing from borehole owners. My question is what is the risk of being infected by the Cholera Bacteria especially in schools who use the water to wash with but not to drink?
