Just as it’s crept into schools, hospitals and offices, omicron has made its way into California’s nursing homes and assisted living facilities, prompting staff shortages that are threatening normal operations and forcing families to contend, once again, with visitor restrictions.

Leading up to Christmas, a few hundred health care workers at skilled nursing facilities across the state had COVID-19. But in the days after the holiday, the number shot up, to more than 5,650 active cases this week. Infections among residents, one of the most highly inoculated groups in the state, have also started to rise. So far, thanks in large part to the vaccines, deaths have remained relatively flat.
