In Lusaka, the capital city of Zambia, M¿decins Sans Fronti¿res (MSF) is responding to the worst cholera outbreaks in the country for many years. Over the last five weeks the number of cholera cases has risen dramatically to more than 4,500, while more than 120 people have lost their lives. MSF teams are working around the clock to treat people affected by cholera and try to contain the spread of the outbreak. MSF has set up three cholera treatment centres (CTC) in Matero, Chawama and Kanyama, with a capacity of 567 beds, and is also supporting 17 cholera treatment units (CTU). Since March 4, MSF teams in collaboration with the Ministry of Health have treated 4,020 patients in the three CTCÕs.
