Port-au-Prince.– Cholera cases are increasing in Haiti as the country heads into the annual rainy season, the United Nations' Office for the Coordination of Humanitarian Affairs said in its monthly bulletin.
According to the humanitarian agency, new cholera cases were found in the western and northern parts of the country and that Haitian health officials recorded 77 new cases a day for the territory in early March, when the rains began.
Health officials said the disease has killed more than 7,000 people and sickened another 530,000. It was likely introduced by a UN peacekeeping unit from Nepal, where the disease is endemic, several months after the January 2010 earthquake.


Does he go by that name these days?
May the good Lord saves Haiti.
However according to Wikipedia,
"The suspected source for the epidemic was the Artibonite River, from which some of the affected people had drunk water. A UN team investigated samples of a suspected sewage spill from a Nepali peacekeeping base that may have infected the river system. Vincenzo Pugliese of MINUSTAH confirmed that the tests were negative for cholera. The US CDC said its tests of "DNA fingerprinting" showed various samples of cholera from Haitian patients were identified as Vibrio cholerae serogroup O1, serotype Ogawa, a strain found in South Asia.
"Cholera cases increase in Haiti due to the rainy season"
So The Rainy Season, NOT THE UNSANITARY CONDITIONS!!!! ARE THE CAUSE.
Interesting......
The two are not a contradiction. The rainy season exacerbates the problem of poor sanitation.
