The numbers are staggering. California reported 52,000 new cases on Thursday, about the same number the entire country was averaging in mid-October. More than 16,000 people statewide have been hospitalized with the coronavirus or suspected cases of it, with more than 3,000 of them in the ICU. There were 393 deaths recorded Wednesday, setting a new single-day record in the state. Some local officials have taken today’s numbers as a cue to tighten their own restrictions. “COVID-19 cases are surging in San Francisco and across the country,” San Francisco Mayor London Breed said in a statement discouraging travel and implementing 10-day quarantines for anyone entering the region. “Hospitals in the Bay Area are close to being overwhelmed. We must do whatever we can to contain the virus and stop its circulation in our community. Now is not the time to travel and risk being exposed or exposing others.”
