"The death toll from the current cholera epidemic in Haiti has exceeded 500, the country's health ministry has said.
Fifty-nine people had died up until and including Thursday, and 617 others had been infected, bringing the total affected to 7,359, the ministry added.
The news came as the local authorities and relief agencies attempted to get clean drinking water to those areas worse affected by Hurricane Tomas.
The storm caused flooding and left eight people dead in western Haiti.
The charity, Save the Children, said that in Leogane, the streets had been turned into "rivers" and some 35,000 people had been affected."
