Around 70,000 refugees have been registered in Yida camp in South Sudan's Unity State, nine miles from the border with Sudan, since 2011. Most have arrived after fleeing the violent conflict in Sudan's Nuba Mountains.
During last year's rainy season, the mortality rate among young children in the camp rose well above the emergency threshold of two deaths per day per 10,000 people, mostly due to infectious diseases related to the camp's poor hygiene conditions, which were further exacerbated by the rains.
Huge numbers of Somalis have left the country’s central regions to seek refuge in the capital, Mogadishu, since July. They have had to leave due to poor agricultural production, loss of livestock because of drought, increasing prices, and perpetual insecurity. Once they reach Mogadishu, however, they are vulnerable to a host of health problems.
