Haiti braces for hurricane as new findings on cholera strain emerge

Aid workers are rushing to prepare for a hurricane that forecasters said could hit Haiti this week. It's a formidable challenge in a nation already coping with a cholera epidemic and trying to help hundreds of thousands still living in tent camps nearly 10 months after a devastating earthquake.

Meanwhile, a recent study found that the cholera outbreak that has killed more than 300 people matches strains commonly found in South Asia.

The finding by the U.S. Centers for Disease Control and Prevention intensifies scrutiny on a UN base above a tributary to the Artibonite River that is home to a contingent of recently arrived peacekeepers from Nepal -- a South Asian country where cholera is endemic and which saw outbreaks this summer.

Health officials said the findings do not prove anything, but speculation is increasing about sanitation on the UN base.
