Nigeria has introduced new protocols for arrivals at all airports after cases of Ebola were confirmed.
The country has declared a national state of emergency following a meeting of the World Health Organisation which called the Ebola outbreak a ‘Public Health Emergency of International Concern’.
The International Health Regulation Emergency Committee said that there should be no general ban on international travel or trade.
But it said areas with cases of Ebola should: declare a national emergency, activate a national disaster/emergency management mechanism and conduct exit screening of all persons at international airports, seaports and major land crossings.
It added there should be no international travel of Ebola contacts or cases, unless the travel is part of an appropriate medical evacuation.
The Foreign Office updated its advice to warn travellers that although the chances of being infected remain low, there are measures that can be taken to prevent catching the disease.
It told visitors to follow advice from the National Travel Health Network Centre.
Meanwhile, US Centers for Disease Control and Prevention (CDC) director Tom Frieden believes the spread of Ebola is "inevitable" given the ease of air travel.
