SCIENCE: Indefinite Safe Sex Urged for Liberian Ebola Survivors. “The Liberian government recommended on Saturday that survivors of Ebola practice safe sex indefinitely, until more information can be collected on the length of time the virus might remain present in body fluids including semen. Previously, male survivors were advised to abstain from sexual intercourse or to use condoms for three months, reflecting that the active virus had been detected for up to 82 days in semen.”
