Cholera has been suspected in Haiti since October but officials have just confirmed that the outbreak has reached Haiti's capital, Puerto Principe. There are about 100 suspected cases in the capital. The country overall has had 544 deaths and 8,000 people enter hospitals for treatment. I was surprised to see that there hasn't been more coverage on this outbreak since Haiti has had so much international aid since the earthquake. Cholera is also a very serious disease with a pretty high mortality rate.

On one hand, it is slightly understandable that a disease of such potency would spread very quickly in a nation that is still recovering. After the earthquake I know that most people lost their previous level of water quality and overall sanitation. Regardless, it is still extremely unfortunate.
