Ebola: Save the Children says Sierra Leone a 'wake-up call'

The Ebola epidemic in Sierra Leone is growing so quickly that healthcare demands are far outstripping supply, a charity has warned.

Save the Children said there were 765 new cases of Ebola reported in the West African state last week, while there are only 327 beds in the country.

The warning comes as experts and politicians meet in London to debate a global response to the crisis.

Mark Buttle, Save the Children's Emergency Water, Sanitation and Hygiene (WASH) advisor, spoke to BBC News about how cultural practices may be putting some people at even greater risk.
