Tests Show Ebola Probably Remained Latent in Liberia

Scientific American reports health officials said on Friday that Ebola probably remained latent in Liberia even after it was officially eliminated in May. Test results showed the strain of the virus in newly detected cases closely resembled earlier infections.
The preliminary findings are based on a new technique analyzing the genetic sequence of the virus. Sources say the findings suggest that transmission was either reactivated by an Ebola survivor--perhaps through sexual intercourse--or continued for weeks undetected. Liberia's first Ebola case in nearly two months was reported on June 30 when the body of a 17-year-old boy, Abraham Memaigar, tested positive for the virus in Margibi County. Since then, a further four cases have been confirmed. Ebola has killed more than 11,200 people across West Africa.
