The Ebola virus can remain in semen for longer than previously thought, suggesting men who survive the disease should always use a condom during sex.
Health officials thought the Ebola virus could remain in semen for about three months, but a recent case in West Africa suggests infection through sex can happen more than five months later, the CBS News reported.
It was recently reported that a 44-year-old Liberian woman, whose infection likely came from a 46-year-old man who had Ebola symptoms 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.
CDC spokeswoman Kristen Nordlund said that 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.
