Some health officials are concerned that current vaccines may not be effective against the South Africa variant, which also raises the prospect of re-infection. The South African variant, also known as the 501Y.V2 variant, is 50% more infectious and has been detected in at least 20 countries. CDC officials told Reuters they would be open to adding additional countries to the list if needed.

CDC officials noted 120 countries currently have mandatory COVID-19 testing requirements for international travel.
