WHO shuts down Sierra Leone Ebola laboratory
The World Health Organisation, WHO, has shut down a laboratory in Sierra Leone after a health worker there was infected with Ebola, a move that may hamper efforts to boost the global response to the worst-ever outbreak of the disease, Al-Jazeera news reports.. At least 1,427 people have died and 2,615 have been infected since the disease was detected deep in the forests of southeastern Guinea in March.
