Angelina Jolie uses her considerable celebrity to draw attention to the world's largest refugee camp.  Some 300,000 Somalis live in Dadaab, Kenya, having fled persistent instability in Somali.

And here is Erin Weir of Refugees International discussing her recent trip to Dadaab.  She says that despite some political progress in Somalia, the size of Dadaab is growing, and stretching the ability of the international community to maintain the camp. 

One issue that Jolie alludes to is the onslaught of malaria that typically accompanies the (coming) rainy season. Refugees are particularly vulnerable to malaria. So, if I may, consider sending a net.
