Specifically, the Nigerian Centre for Disease Control  said: "We urge the public to restrict all non-essential travel to these countries" while added that the government is temporarily suspending the issuance of all visas on arrival.

Countries that have reported more than 1.000 cases, including the United States, Britain, Germany, China, Italy, Iran, South Korea and Japan, won't be able to enter Nigeria.

The entry ban will be into effect for an initial period of four weeks, and travelers who had visited any of the 13 countries would be under a 14-day quarantine.

For the records, Nigeria at the moment has 12 COVID-19 confirmed cases, according to the live map.
