A group of Caribbean countries have announced bans on entry to foreigners who have travelled through the three West African countries most affected by Ebola.

Jamaica said it would not accept travellers from Liberia, Guinea and Sierra Leone for the time being.

Guyana, the island of St Lucia, Haiti and Colombia also introduced a ban.

In the United States, President Barack Obama has resisted pressure to put similar bans in place.

Jamaica's travel ban extends to "persons ordinarily resident in Guinea, Liberia and Sierra Leone as well as persons who have travelled to or transited through Guinea, Liberia and Sierra Leone, within 28 days of having departed from these countries".
