Things are calmer now at the main hospital in South Sudan's Yida refugee camp. The hospital is run by Doctors Without Borders (MSF).Many beds in this makeshift tent hospital are still full, but according to MSF, the situation is finally manageable.From mid-June through mid-July, a wave of disease hit the camps, sending mortality rates soaring.This was coupled with a rush of new refugees, as many as 1,000 per day.Since then, the situation has improved. At one of three Outreach Therapeutic Program centers, refugees come in for nutrition monitoring and evaluation.Mothers receive special food rich in vitamins and nutrients to keep their children healthy.The lines are still long, but MSF says the refugees are generally less malnourished."Now there is need," said Marie, a nurse with MSF in charge of this clinic. "It's not so catastrophic like it was in July.But it's very― it can change quickly. If malaria comes, if cholera comes or if more people come, very quickly, it can be like in July.The refugees at Yida come from the heart of Sudan's South Kordofan State.Fighting broke out in June of last year between the government and the rebel SPLA-North, which was part of South Sudan's own rebel SPLA during the Sudanese civil war.The camp now has more than 65,000 refugees who fled intense fighting and aerial bombardments by Sudanese warplanes.
