Factbox - Travel bans issued in reaction to Ebola

(Reuters) - The deadliest outbreak on record of the Ebola virus has prompted some countries to respond with travel bans, in an attempt to curb the spread of the deadly virus.

The World Health Organization has recommended against any general ban on travel or trade with the West African countries that have been affected by the epidemic. The three countries most affected by the virus are Guinea, Liberia and Sierra Leone. There were a small number of cases in Senegal, Nigeria and Mali. The WHO declared Senegal Ebola-free on Oct. 18 and declared Nigeria Ebola-free on Oct. 19.
