"Nearly 50 people have contracted cholera while attending a health conference in Kenya's capital.
The infected delegates were among hundreds who had gathered for the four day forum organised by the Ministry of Health at a Nairobi hotel on Tuesday.
They have been isolated in a city hospital, but health officials say the number of people infected may rise.
It is unclear how they caught the disease, which has led to five deaths in the past month."
