Aid workers recover after experimental ebola drug

The drug, developed by Mapp Biopharmaceutical Inc, was used to treat the aid workers who were exposed to the disease in Liberia.

Dr Kent Brantly, of Samaritan’s Purse returned to the a US a week ago and his colleague Nancy Writebol of SIM USA flew back via medical aircraft on Tuesday.
