The board’s chairman said Thursday that San Mateo County employees and people visiting county buildings will have to wear face masks, whether or not they begin with vaccinations.
Although San Mateo County has a remarkable vaccination rate — more than 88% of those 12 and eligible for the shots have been vaccinated — supervisor David Canepa said “the virus knows no county boundaries.” And COVID-19 infections and hospitalizations are on the rise, he said, mainly among unvaccinated people.
“The bottom line is — we’ve been saying this for months — that people need to be vaccinated, it’s more important than ever,” said Canepa, the board’s chairman. “It is because of the unvaccinated that we find ourselves in this situation, so everyone should get vaccinated.”
The county’s 7-day average rate of daily new cases per 100,000 people fell from 1.1 at the end of May to 6.6 as of Thursday, according to state figures. The 14-day average of hospitalized patients, which fell to 12.7 on July 15, is now 16.3.
Much of that increase is believed to be driven by the highly permeable delta version of the virus, which ravaged India in the spring and has since spread globally and across the US, where the US Centers for Disease Control and Prevention Director Dr. Rochelle Valensky said this week that it accounted for 83% of cases.
