BOGOTA (Thomson Reuters Foundation) - Cholera will continue to kill and infect Haitians as long as they lack access to clean water and sanitation, with a thousand new cases reported each week, health experts say.

Cholera, a water-borne disease caught by drinking and using contaminated water, has killed nearly 9,000 Haitians and infected 732,000 since it broke out in the country in late 2010.
