SIERRA LEONE -- As if the Ebola virus weren't horrifying enough, now sick people are scrounging for the blood of survivors. The stuff is red-hot on the black market.
The World Health Organization is trying to stop the trade, out of fears that other illnesses, like HIV could spread. It has not even proven that survivor blood, also known as "convalescent serum" actually works. But it's said to have antibodies that can fight the disease.
Convalescent serum has been reportedly used to treat American aid worker Rick Sacra, who is hospitalized in Nebraska.
