MONROVIA, LIBERIA - AUGUST 22: Martha Korpu mourns the death of her brother David Korpu, a registered nurse, after he died of the Ebola virus at the Doctor's Without Borders (MSF), Ebola treatment center on August 22, 2014 near Monrovia, Liberia. The MSF center reached functional capacity Friday and had to turn away new arrivals until additional international staff arrive this weekend to treat more patients. International agencies and the Liberian government are stuggling to keep up with the growing epidemic, which has killed at least 1,350 people in West Africa and more in Liberia than any other country.
