Study show Ebola virus resurfaces in semen after six   months of recovery

A study has shown that Ebola persists in the semen of male survivors much longer than previously thought.

The report in the New England Journal of Medicine found two-thirds of men had Ebola in their semen up to six months after infection, and a quarter of infection after nine.

A separate study, in the same journal, reports Ebola being spread through sex with a survivor six months after symptoms had started.

Men who have survived Ebola are being encouraged to wear condoms.  Previous outbreaks of Ebola had shown the virus was present in semen for 82 days after the onset of symptoms.

However, with huge numbers of Ebola-survivors now in West Africa, there is concern about how long the virus persists and if that poses a threat.
