A man is in hospital in Canada with symptoms of a haemorrhagic fever resembling the Ebola virus, a health official has said.
The man had recently returned from Liberia in the west African region, currently suffering a deadly outbreak of an unidentified haemorrhagic fever.
He is in isolation in critical condition in Saskatoon, the largest city in Saskatchewan province.
A provincial medical official said there was no risk to the public.
Dr Denise Werker, the province's deputy chief medical officer, declined to say how long the man had been in Africa but said he only fell ill after returning to Canada.
She said that was in line with the profile of common deadly haemorrhagic fever viruses Lassa fever and Ebola, which have an incubation period of up to 21 days.
