Los Angeles County is now recording more than 10,000 coronavirus cases a week — a pace not seen since March — an alarming sign of the dangers the Delta variant poses to people who have not been vaccinated and heightening pressure on health officials to reverse the trend.
A Los Angeles Times data analysis found L.A. County was recording 101 weekly coronavirus cases for every 100,000 residents, up from 12 for the seven-day period that ended June 15. That means the county has surpassed the threshold to have “high” community transmission of the disease, the worst tier as defined by the U.S. Centers for Disease Control and Prevention. A region must hit 100 or more weekly cases per 100,000 residents to enter the worst tier.
Two months after the Centers for Disease Control and Prevention said vaccinated individuals didn’t need to wear masks in most settings, a growing number of experts are warning it’s time to put them back on.
First, there was Los Angeles County, where the rising menace posed by the delta variant of the coronavirus prompted health officials to reimpose a mask mandate. Then, Bay Area health officers on Friday recommended that residents of seven counties and the city of Berkeley, Calif., resume wearing masks indoors. Mask mandates are being discussed, too, in coronavirus hot spots such as Arkansas and Missouri, where cases have sharply increased in recent weeks and many residents remain unvaccinated.
