It took nearly a year since the start of Haiti’s cholera epidemic for scientists to get conclusive proof that the cholera bacteria in Haiti are identical to bacteria in Nepal. The only reason it took so long to discover that Haiti’s cholera came from Nepal is because scientists had until now not bothered to compare the cholera from Haiti to cholera from Nepal.
Cholera, a "disease of poverty" caused by lack of access to clean water, has spread to Haiti's capital city of Port au Prince. At a small, desolate camp of ripped tents nearby, a gleaming water tank is propped up on bricks. But it’s empty.
The cholera epidemic has killed 250 Haitians and over 3,000 more are infected and may die. This cholera is caused by drinking dirty, toxic water. According to Haiti’s health minister, cholera “can kill in three hours because once the diarrhea starts it doesn’t stop.”
