CDC urges vaccinated people to wear masks again in the United States

The new recommendation urges fully vaccinated people to wear masks indoors when in areas with "substantial" and "high" transmission of COVID-19, which includes nearly two-thirds of all US counties

Washington (US): The Centers for Disease Control and Prevention updated its mask guidance to prevent further spread of the Delta variant in the United States, by mandating vaccinated people to wear masks in certain situations. The recommendation urges fully vaccinated people to wear masks indoors when in areas with "substantial" and "high" transmission of COVID-19, which includes nearly two-thirds of all US counties.  "In recent days I have seen new scientific data from recent outbreak investigations showing that the Delta variant behaves uniquely differently from past strains of the virus that cause COVID-19," CDC Director Dr Rochelle Walensky told reporters on Tuesday (July 28, US time). Soon after the announcement made by CDC, a statement issued by the White House stated that President Joe Biden and White House officials will resume wearing masks indoors when traveling to parts of the nation with high Covid transmission rates.
