GOMA, Congo — The first case of cholera has emerged among thousands of people in an impromptu refugee camp in eastern Congo who fled fighting between a new rebel group and government forces backed by UN peacekeepers, Doctors Without Borders reported Friday. Mission chief Dr. Patrick Wieland said that MSF, as the aid group is known by its French initials, has set up an isolation clinic tent at Kanyaruchinya on the outskirts of the provincial capital of Goma, where between 10,000 and 20,000 civilians have taken refuge in a school, a church and nearby grounds. Wieland said there are not enough toilets for the people who fled fighting last week in Rutshuru and Kiwanja, about 80 km north of Goma. — AP
