To maximise protection from the Delta variant and prevent possibly spreading it to others, wear a mask indoors in public if you are in an area of substantial or high transmission,” the US Center for Disease Control and Prevention (CDC) said in its latest guidance.
More than two months ago, on May 13, the CDC had recommended that people who are fully vaccinated - those who received both shots of the two-dose Covid-19 vaccines such as Moderna and Pfizer - need not wear masks both indoors and outdoors.
The Alpha variant of the coronavirus, which was prevalent at that time, was not as highly transmissible as Delta, which has been spreading rapidly in the United States feeding primarily on the unvaccinated.
The CDC has called an ongoing surge in Covid-19 cases a “pandemic of the unvaccinated”.
Daily tallies of new cases have been spiking, going up to 89,418 on Monday, according to the US-based Johns Hopkins University’s coronavirus tracker.
Almost all new hospitalisation cases and deaths in the country are of those infected by the Delta variant of the virus.
US President Joe Biden called the new guidance “another step on our journey to defeating this virus” and appealed to Americans who live in the areas covered by the CDC guidance to follow it.
“I certainly will when I travel to these areas,” he said, underscoring his support for it.
