Here’s why the mask mandate isn’t coming back: Marin County’s COVID-19 case rates are now the highest in the Bay Area.
Bob Wachter, chair of the department of medicine at UCSF, tweeted on Tuesday that even as he hoped that the omicron variant will be less severe than the delta strain of the coronavirus — as preliminary data may indicate — “if Omicron is somewhat less severe but far more transmissible, that’ll still be nasty.” Wachter also noted that the delta variant “remains the major threat & it’s killing >1000 in U.S./day.”
