A cholera epidemic sweeping through West and Central Africa has infected more than 85,000 people, killing at least 2,466 so far this year, United Nations aid agencies said on Tuesday.
The virulent diarrhoeal disease, one of the biggest in the vast region's history, is spreading quickly along waterways between and within countries, causing an "unacceptably high" rate of fatalities, the UN Children's Fund UNICEF said.
