Outbreak: Nigeria On Heightened Alert As Business Man Dies of Deadly Ebola After Arriving Nigeria From Togo

Unsuspecting passengers would have thought a passenger just having a stomach bug when earlier this week, a Liberian man vomited and had a high fever on board a passenger plane to Nigeria.

Quick thinking officials immediately quarantined him upon arrival in Lagos but later died in hospital from the deadly Ebola virus spreading through West Africa, on Friday. Nigerian health minister Onyebuchi Chukwu said it was the first case of Ebola to be confirmed in Nigeria since the current outbreak emerged early this year. The disease is already rampaging through Liberia, Guinea and Sierra Leone, with death toll close to 700. Authorities are investigating anyone who may have come into contact with the deceased man.Mr Chukwu said: "All ports of entry into Nigeria, including airports, seaports and land borders, are placed on red alert.

"Ministry of health specialists have been positioned in all entry points. Active surveillance has also been stepped up."

He added: "We have already got in touch with all the passengers. We are monitoring and investigating." Liberia's chief medical officer identified the Ebola victim as a government official with the finance ministry. He flew to Nigeria to attend an international conference. Ebola, one of the world's most deadly and contagious diseases, has killed at least 660 and infected 1,093 in Sierra Leone, Liberia, Guinea, and now Nigeria, according to the World Health Organisation.
