(Reuters) Eleven people have died and five are in the hospital, Liberian officials said on Friday, after contracting a mystery illness the World Health Organisation (WHO) said was linked to attendance at the funeral of a religious leader.

“We are still investigating. The only thing we have ruled out is … Ebola,” said Liberia’s Chief Medical Officer Francis Kateh, adding samples from the victims had been sent abroad for further testing.

On Wednesday, the WHO said Liberian health authorities were taking rapid precautionary steps after eight people died of a mystery illness, 10 months after the end of a two-year Ebola virus outbreak.
