LEDA MAKESHIFT ROHINGYA REFUGEE, BANGLADESH - 2011/03/27: A child shows the symptoms of small pox in the clinic of the makeshift or "unregistered" Leda Rohingya refugee camp. A population estimated by the camp's officials to 13,700 Rohingya live in the Leda camp in Southern Bangladesh. The Rohingya is a Muslim ethnic community from Myanmar Arakan State. They represent one of the largest stateless populations on Earth, whether in Myanmar where an estimated one million people don't have the citizenship status or in other countries, particularly in Bangladesh, where possibly another 500,000 live as refugees or illegal migrants..
