Uganda, Ocea camp - Kokobo district is home of about 10,000 South Sudanese refugees. MSF is planning to do mobile clinics and water supply in 2 refugees' camps. *** Local Caption *** Since mid-december 2014, more than 40,000 South Sudanese refugees have arrived in northern Uganda to flee the violence in Jonglei and Unity states. And the influx of people has not stopped. From an average of 2,500 new arrivals per day, the number of new arrival has dropped early January to about 700 persons per day. Dzaipi transit camp, located at about 7km from the border - was initially set up for 3,000 persons and was rapidly overcrowded. Refugees lived under the trees or at best in the school building. The local health centre was overwhelmed by the number of patients coming in. Refugees were lacking the basics such as clean water, food and latrines. MSF has set up an emergency operation to respond to their needs : water and sanitation, outpatient and inpatient consultations, maternity, vaccination and screening for malnutrition. MSF teams currently work in the three refugee camps and will adapt their activities according to the evolution of the situation.
