More California counties recommend wearing masks inside amid delta variant concerns - KCRA Sacramento

More California counties are recommending that residents wear masks indoors, even if they're fully vaccinated against COVID-19.

Stanislaus County said on Monday that people who are fully vaccinated may want the "extra protection" of wearing a mask indoors.

People who are 65 or older, have risk factors for COVID-19, and any conditions or medications that lower their immune system should also mask up indoors, the county said.

Monterey, Napa, San Benito and Santa Cruz counties recommended on Monday for everyone to wear masks indoors in public places.

Several Bay Area counties on Friday also jointly recommended that vaccinated people mask up indoors again at public buildings, offices or businesses to help limit the spread of the highly infectious delta variant.
