United Nations health investigators say the strain of cholera, that killed more than 4,000 people in Haiti, came from south Asia.

The UN officials say they traced the strain back to a river near a UN peacekeeper camp, that was occupied by troops from Nepal.  The UN admits that sanitation conditions at the camp were below standards.

The UN investigators refuse to blame the Nepalese, even though they say the evidence “overwhelmingly supports” that the Haiti cholera strain came from south Asia.

The cholera epidemic is not over for Haiti.  The United Nations predicts another 800,000 Haitians could become sick this year.
