The death toll in Haiti's cholera outbreak has risen to 917 as officials struggle to contain the growing epidemic threatening the quake-ravaged country.
The figures, issued on Sunday, nearly a month after the disease took hold, had increased by about 120 since Friday.
Authorities said 14,642 people had been treated in hospital, about 2300 more than on Friday.
Officials fear the scale of the epidemic could increase exponentially if cholera infiltrates makeshift camps in Port-au-Prince where hundreds of thousands of earthquake survivors live in cramped and unsanitary conditions.
The earthquake which struck Haiti in January flattened much of the capital, leaving more than 250,000 people dead and an estimated 1.3 million of the country's 10 million population displaced.
The UN is appealing for $US164 million to treat the disease in the next year.
