"Cholera is a waterborne disease resulting from inadequate access to safe drinking water and sanitation. Despite efforts to keep its spread under control, cholera remains a serious disease in many parts of the world." Center for Disease Control.
Dr. Eric Mintz says:
"Inexcusably, the completely preventable ancient scourge of cholera rages among poverty-stricken and displaced people today, with as many as one in five persons with severe illness dying for lack of safe drinking water and sanitation and a simple therapy consisting of salt, sugar, and water. Cholera, a dreaded waterborne disease of centuries past, remains a troubling barometer — and often a fatal consequence — of inadequate access to safe drinking water and sanitation."

That's right, over a century and a half ago, a physician in London discovered water transmitted cholera. In the late 1800's a Bristish civil engineer figured out a way to engineer the water system to prevent cholera. So why are we still living with the disease? It's very inexpensive to prevent.
