There is one disaster that was brought to Haiti directly by people, and not by nature. It was not caused by shifting tectonic plates or extreme weather (or climate change). That disaster is the cholera epidemic that struck Haiti two years ago.
While the dead are buried, thousands maimed in the quake gather at camps to receive medical treatment. And millions wait for the next flash flood, hurricane, or earthquake to devastate their living arrangements.
The IMF has proposed a plan that might help Haiti build a new foundation for nation building. But if this plan is to succeed it will need to contain the global drug trade that dominates Haiti's economy.
