KAMPALA, Uganda — An outbreak of typhoid fever has infected hundreds of people in the Ugandan capital, Kampala, and looks likely to spread as the rainy season gets under way, a senior health official said on Wednesday.

At least 4,000 suspected cases of typhoid fever have been reported, 400 of which have been confirmed, said Dr. Anthony Mbonye, the director of health services at Uganda’s Ministry of Health.

Mbonye said the disease’s epicenter is a slum in downtown Kampala where many were sickened by contaminated water and fruit juices.

At least two people have died of the bacterial disease.
