Two people have fallen ill with Ebola in Guinea after two weeks with no new confirmed cases of the disease in West Africa, the World Health Organization said on Friday.
WHO spokeswoman, Margaret Harris, told a United Nations briefing in Geneva that one case was in Forecariah, western Guinea, and appeared to be linked to a previously known chain of infection, while the other was in the capital Conakry.
Ebola transmission is considered to be over once a locality has gone 42 days without a new case of the disease. The other two countries that were worst hit by the epidemic were Liberia, which was declared transmission free on September 3, and Sierra Leone, which is counting down another 22 days until it is clear, Reuters reported.
The worst outbreak on record has been largely stopped in its tracks after killing more than 11,000 people.
But the WHO has repeatedly warned against prematurely assuming the outbreak is over because the virus could pop up again until the 42 days are over.
“On the bumpy road we keep talking about, the high risk of recurrence, once again we are navigating a few bumps,” Harris said. “Of course we didn’t want it, but we did expect it. Guinea hadn’t got to the stage where we were looking at 42 days.”
Even after that period, Ebola may lurk in the population. This month a study showed the semen of male survivors can harbour the virus for nine months, while a British nurse has fallen critically ill again 10 months after recovering from Ebola.
