The most widespread Ebola epidemic in history is currently ongoing in West Africa. Health officials had previously thought that the Ebola virus could remain in semen for about three months.
However, a recent case in West Africa suggests infection through sex can happen more than five months later. Thus suggesting that men who survive the disease should always use a condom during sex.
It was recently reported that a 44-year-old Liberian woman, who was likely to be infected from a 46-year-old man who had Ebola symptoms in September 2014, fell ill in March, a week after sex with him, and died, but another woman he had sex with around the same time tested negative. Kristen Nordlund, Center for Disease Control spokeswoman, said, "There have been fewer than 10 such cases and it's been difficult to pinpoint that sex was the only way they may have been infected."
