The Ebola outbreak is believed to have killed more than 3,400 people in West Africa and has taken the biggest toll in Liberia. There aren't enough beds in isolation units to keep up with the hundreds who get sick each week.

The three hardest-hit countries of Liberia, Guinea and Sierra Leone had too few doctors and nurses to begin with, and a tremendous number of infections in health care workers during the outbreak has only further reduced their numbers. With more than 370 health care workers sickened by the disease so far, many other clinicians are afraid to care for Ebola patients.
