Liberia’s chief medical officer has put herself under quarantine for 21 days, after one of her assistants died from the deadly Ebola virus. Bernice Dahn, a deputy health minister, said she had no symptoms but wanted to take every precaution. The World Health Organisation (WHO) says more than 3,000 people have died from Ebola in West Africa. Liberia has been the worst hit by the disease, accounting for 1,830 deaths – 150 in the last two days alone.
Health workers have been particularly vulnerable to the virus, which is spread by the infected bodily fluids of patients.
