Samaritan's Purse, based in North Carolina, said in a statement that Dr. Kent Brantly was being treated at an isolation center in a hospital in Monrovia, Liberia's capital. Brantly is the medical director for the aid organization's case management center in the city. Brantly, 33, has been working with Samaritan's Purse in Liberia since October 2013 as part of the charity's post-residency program for doctors, group spokeswoman Melissa Strickland told The Associated Press. The organization's website says he had worked as a family practice physician in Fort Worth, Texas. There is an Ebola epidemic that has affected four African nations, Guinea, Liberia, Sierra Leone, and a case in Nigeria. This is the largest Ebola epidemic known.
