There have been 20 cases of Ebola being imported by someone travelling from a country of widespread transmission to Nigeria, with eight confirmed deaths. The US and Senegal have both confirmed one case each. The US Centers for Disease Control and Prevention (CDC) said in September that the virus might have been successfully contained in Nigeria and Senegal.
In October, a nurse in Spain became the first person to contract the deadly virus outside of West Africa, after treating two Spanish missionaries who had eventually died of Ebola in Madrid.
