Via BBC News: Travel ban to Ebola affected countries, UK officials say. Excerpt:
The UK Foreign and Commonwealth Office says all travel to Sierra Leone, Guinea and Liberia should be avoided - unless essential, due to the Ebola outbreak.
British Airways has suspended flights to Sierra Leone and Liberia and other airlines are taking similar measures.
Such flight restrictions may make it increasingly hard for people working in these areas to leave, the FCO warns.
Meanwhile scientists have announced plans to trial an Ebola vaccine on UK volunteers this September.
The latest figures show that more than 1,550 people have died from the virus, with more than 3,000 confirmed cases - mostly in Guinea, Liberia and Sierra Leone.
The FCO say British nationals working in these countries "should be aware that the narrowing range of commercial flight options and growing restrictions on travel may make it difficult to leave, particularly at short notice".
The government officials advise people should stay in contact with employers, discussing any help and support they can provide.
