HONG KONG - Hong Kong's Centre for Health Protection said Sunday night that a Nigerian man, earlier suspected of having the deadly Ebola virus, has tested negative at Princess Margaret Hospital.

It was the first suspected case of Ebola, which is spread through blood and body fluid, in Hong Kong following an outbreak in West Africa.

The 32-year-old who had been vomiting and suffering from diarrhea, both symptoms of the disease, arrived in Hong Kong on Thursday.

He was sent to the hospital from ChungKing Mansions where he had been staying at a guesthouse.

More than 900 people have died in the Ebola outbreak in West Africa. The World Health Organization has described the outbreak as a global emergency and the worst in four decades. The disease is fatal in 50 to 90 percent of cases.

According to the UK's National Health Service website, an infected person will typically develop a fever, headache, joint and muscle pain, sore throat, and intense muscle weakness.

These symptoms start suddenly, between two and 21 days after becoming infected, but usually after five to seven days.
