Esperance Zawadi, 18, lies by her 11-month-old son Steve Kwizera in a tent set outside the Kibati hospital in Kibati, north of Goma, eastern Congo, Monday Aug. 6, 2012. Steve is under observation for symptoms of cholera. Doctors Without Borders' Christian Masudi said the lack of hygiene and the overpopulation of the area created by the influx of internally displaced people were key factors in the potential explosion of diseases such as cholera.
