ABUJA/GENEVA, July 25 (Reuters) - A Liberian man who died in  Nigeria's commercial capital Lagos on Friday tested positive for  the deadly Ebola virus, Health Minister Onyebuchi Chukwu said.                
Patrick Sawyer, a consultant for the Liberian finance  ministry in his 40s, collapsed on Sunday after flying into  Lagos, a city of 21 million people, and was taken from the  airport and put in isolation in a local hospital. Nigeria  confirmed earlier on Friday that he had died in quarantine.                
"His blood sample was taken to the advance laboratory at the  Lagos university teaching hospital, which confirmed the  diagnosis of the Ebola virus disease in the patient," Chukwu  told a press conference on Friday. "This result was corroborated  by other laboratories outside Nigeria."                
However, at a separate press conference held by the Lagos  state government at the same time, the city's health  commissioner, Jide Idris, said that they were only "assuming  that it was Ebola" because they were "waiting for a confirmative  test to double check" from a laboratory in Dakar.                
Paul Garwood, spokesman for the World Health Organization  (WHO) in Geneva, said the U.N. health agency was also still  waiting for test results.                
"We're still waiting for laboratory-confirmed results as to  whether he died of Ebola or not," he said.                
It could not be immediately determined why there was a  contradiction in the comments from central government and city  officials.                
If confirmed, the man would be the first case on record of  one of the world's deadliest diseases in Nigeria, Africa's  biggest economy and with 170 million people, its most populous  country. Ebola has killed 660 people across Guinea, Liberia and  Sierra Leone since it was first diagnosed in February.                
Sawyer was quarantined on arrival and had not entered the  city, a Nigerian official told Reuters.                
"While he was quarantined he passed away. Everyone who has  had contact with him has been quarantined," the official said.                
Liberia's finance minister Amara Konneh said Sawyer was a  consultant for the country's finance ministry.                
"Our understanding is that the cause of death was Ebola,"  Konneh told Reuters.                
The victim's sister had died of the virus three weeks  previously, and the degree of contact between the two was being  investigated by Liberian health ministry officials, he said.                
Earlier on Friday, WHO spokesman Paul Garwood said: "I  understand that he was vomiting and he then turned himself over  basically, he made it known that he wasn't feeling well.  Nigerian health authorities took him and put him in isolation."                
Nigeria has some of the continent's least adequate  healthcare infrastructure, despite access to billions of dollars  of oil money as Africa's biggest producer of crude.                
Some officials think the disease is easier to contain in  cities than in remote rural areas.                
"The fear of spread within a dense population would be  offset by better healthcare and a willingness to use it, easier  contact tracing and, I assume for an urban population, less  risky funerary and family rites," Ian Jones, a professor of  virology at the University of Reading in Britain, said.                
"It would be contained more easily than in rural  populations."                
There have been 1,093 Ebola cases to date in West Africa's  first outbreak, including the 660 who have died, according to  the WHO.
