US Scientists have discovered a possible cure for all five known Ebola viruses, one of which ravaged West Africa in recent years. <br/><br/>The so-called broadly neutralizing antibodies were discovered in the blood of a survivor of the West African epidemic. <br/><br/>Kartik Chandran, a Professor in the Department of Microbiology and Immunology at the Albert Einstein College of Medicine in Bronx, New York, helped identify the antibodies. <br/><br/>He is optimistic that the antibodies can be used as a single therapy to treat all Ebola viruses.<br/><br/>The deadly virus killed more than 11,000 people of the nearly 29,000 who became infected in Liberia, Guinea and Sierra Leone.
