The death toll from a cholera epidemic in Angola has exceeded 1,300 people and the number is still rising daily, a medical aid group said on Wednesday.
Richard Veerman, from Medecins Sans Frontieres' Angola programme said at least 31 people had died in the last 24 hours from the waterborne, bacterial disease that so far has infected more than 35,000 people.
He said the 31 deaths in the day before, was the official number of reported deaths, but that the real toll for the day could be three times higher.
The major outbreak, MSF said, is an illustration of how Africa is being crippled by preventable diseases because of poverty and lack of infrastructure.
The UN reported the fatality rate at about 4 percent - far above the one percent the World Health Organisation considers average during cholera outbreaks.
Cholera can be treated easily, but is a major killer in developing countries. It is transmitted through contaminated water and is linked to poor hygiene, overcrowding and inadequate sanitation.
