A UN employee who contracted Ebola while working in Sierra Leone has been evacuated to France for treatment, reports AFP. The UN worker has been placed under isolation in a high security military training hospital near Paris, where a French nurse who contracted the virus in Liberia recovered earlier this autumn. Though there have been about 500 reports of possible Ebola infections in France since June, none have tested positive. France has 12 research hospitals equipped to deal with Ebola cases. Ebola’s toll on Sierra Leone could be much greater than previously thought, with entire villages killed off by the virus. This means up to 20,000 people could have succumbed to the disease by now, a senior coordinator for Doctors Without Borders (MSF) told AFP.
