International aid groups are trying to stop the spread of cholera in Haiti's capital Port-au-Prince, where many earthquake survivors live in makeshift camps and dirty slums. Cholera strikes so fast that it is sometimes called the lightning disease. Cholera can kill people in a matter of hours . Waterborne cholera bacteria spread easily in unsanitary conditions where supplies are shared for cooking and washing. After the initial outbreak is under control, health officials will have to do some long-term planning. One of the ways to keep cholera from spreading is to upgrade the sanitation system in Haiti.
