The UK is to introduce enhanced screening for the Ebola virus at Gatwick, Heathrow and on the Eurostar.
Passengers arriving at these points from the West African countries of Liberia, Sierra Leone and Guinea will have their recent travel history checked with “possible medical assessments” also being carried out.
The Ebola outbreak has already killed more than 3,000 people and infected more than 7,200, mostly in West Africa.
The UK government had previously ruled out ‘enhanced screening’ calling the checks “impractical” and “ineffective”.
Health Secretary Jeremy Hunt has warned it is "entirely possible" Ebola could spread to Britain.
The announcement came shortly after the US confirmed enhanced screening at five major US airports from the worst hit countries in West Africa.
Passengers flying into Chicago O’Hare, New York JFK, Newark, Washington Dulles and Atlanta will have their temperatures taken, answer a travel health questionnaire and will be visually assessed for illness.
