Haiti cholera deaths rise sharply as storm threatens

The number of people known to have died from a cholera epidemic in Haiti has increased markedly, as a tropical storm threatens to make matters worse.

Health officials say 105 more people have died since Saturday, bringing the total to 442. They said there had been a 40% jump in the number of new cases.

Aid agencies fear the outbreak could worsen further, if heavy rains associated with Tropical Storm Tomas hit the island, as sanitary installations could flood and contaminate drinking water.

Dr Jordan Tappero, an epidemiologist and team leader for the US Centers for Disease Control in Haiti, spoke to the BBC from Port-au-Prince.
