San Mateo County is now recommending that everyone, regardless of vaccination status, wear a mask indoors. The joint announcement with eight other Bay Area jurisdictions came on Friday in response to an uptick in COVID-19 cases due to the more transmissible Delta variant.
While COVID-19 vaccinations have proven effective against the variant, the new recommendation advises all residents to mask up indoors to protect those who remain unvaccinated.
âThe epidemic is spreading faster in communities because the virus is more contagious,â Louise Rogers, chief of San Mateo County Health, wrote in a press release. âThe good news is that the vaccines are effective against the Delta variant.â
