Nigeria 'placed on red alert' over Ebola death
Nigeria says it has put all entries into the country on red alert after confirming the death of a Liberian man who was carrying the Ebola virus.
The man died after arriving at Lagos airport on Tuesday, in the first Ebola case in Africa's most populous country.
Surveillance has been stepped up at all "airports, seaports and land borders", says Health Minister Onyebuchi Chukwu.
Since February, more than 660 people have died of Ebola in West Africa. The spread began in southern Guinea moved to Liberia and Sierra Leone marking the world's deadliest outbreak to date.
Officials have identified the 40-year-old man as an employee of the Liberian government but had “avoided contact with the general public”.
Mr Chukwu confirmed that the other passengers on board the flight had been traced and were being monitored.
Health specialists have been deployed at all entry points into the country, he added.
The virus, which kills up to 90% of those infected, spreads through contact with an infected person's bodily fluids.
Patients have a better chance of survival if they receive treatment early.
