LOS ANGELES (AP) — New omicron variants are again driving hospital admissions and deaths higher in recent weeks, causing states and cities to rethink their responses to COVID-19 and the White House to step up efforts to alert the public. Some experts say the warnings are too little, too late. The highly transmissible variants have shown a remarkable ability to get around the protection offered by vaccination. Health officials say Los Angeles County, home to 10 million residents, is facing a return to a broad indoor mask mandate later this month if current trends in hospital admissions continue.
