After a precipitous drop over the past two months, California’s COVID-19 trends have hit a plateau. Cases have fallen only 5% in the past week and the test positive rate inched down a tenth of a percentage point. In a worrisome sign, cases in Europe are starting to climb again as winter approaches. Even so, rules and tracking in the U.S. continue to be eased: The CDC said Thursday that it will stop reporting case and death data on a daily basis and has quietly dropped its masking recommendation for school nurses’ offices. On a brighter note, Moderna released safety data for its bivalent booster and a small NIH-backed study suggests that antiviral medication Paxlovid does not cause COVID-19 rebound.
