CDC recommends masks for vaccinated people in high transmission areas

The Centers for Disease Control and Prevention (CDC) is issuing recommendations that requesting vaccinated Americans to resume wearing masks indoors if they belong to an area with high transmissibility of the COVID-19 virus.

The guidelines further state that individuals with underlying conditions that may make them more likely to contract the virus should practice the precaution of wearing masks, applicable also to people residing with vulnerable individuals. Teachers, school staff, students, and visitors inside schools from kindergarten to 12th grade come under the fold of this new guidance.

The vaccinated people in just under half of the counties in the country which have high transmissibility, mask-wearing is recommended to be a common practice indoors again. Several counties and even urban centers such as Los Angeles, St. Louis, and Miami-Dade fall under the category of high transmission counties.

Transmissibility of a region is labeled as high when 100 or more new cases per 100,000 in the last week are reported, and 10% or higher positive NAATs in that period. The degree of high transmission may vary, for example, Salt Lake Country in Utah at just over 100 cases per 100,000 to counties like Pulaski County in Arkansas recording almost 500 cases per 100,000.

Just a shy of half of all U.S. counties, 46.43% have been identified as high transmission regions so far, according to the CDC, an increase of over 17% from seven days ago.

Counties with the possibility of substantial transmission make up 17.02% of the U.S.; 27.2% of counties are considered at a moderate level; 9.31% are at a low level.
