In Los Angeles, county figures show that Covid-19 infections have increased twentyfold in a month. In San Francisco, they’ve almost tripled in two weeks and, overall, California’s hospitalization numbers have increased by 58%, according to New York Times data.
Despite the fact that California is one of the country’s most vaccinated states, experts blame the highly contagious Delta variant for a new surge that has disrupted businesses’ and politicians’ plans to celebrate the state’s reopening.
“Primarily we’re seeing infections in the unvaccinated,” said George Rutherford, an epidemiologist at the University of California, San Francisco, citing earlier statistics from Los Angeles which found 99.6% of new cases there were in the unvaccinated. “We’re seeing the Delta variant’s extra strength.”
Even with New York Times figures showing nearly 77% of the state’s adults having gotten at least one shot of vaccine, that leaves plenty of unprotected people to transmit the virus, Rutherford said.
