Fueled by rapid spread of the Delta variant, at least 140 recent coronavirus outbreaks have struck workplaces in Los Angeles County — a 150% increase since the middle of July — officials said Wednesday, July 28. Meanwhile, public health leaders posted another 15 virus-related deaths and 2,454 new cases.

The outbreaks illustrate that the virus is still alive and spreading in the county as well as statewide. California leaders rekindled the state’s indoor-mask guidance Wednesday, echoing the county’s revived mandate of nearly two weeks ago.
