Empty Ebola beds in Liberia pose riddle for health workers

MONROVIA/ABIDJAN (Reuters) - Health workers in Liberia are struggling to tell whether a growing number of empty beds at Ebola treatment centres is a sign that the country's ramped up response to the disease is working - or just a lull in the epidemic.

Of the West African countries hit by the 11-month outbreak, Liberia has suffered the most deaths. The virus has killed nearly 5,000 people there and in neighbouring Sierra Leone and Guinea - though numbers could be far higher owing to under-reporting of cases, the World Health Organisation (WHO) warned.
