Amid new LA County mask mandate, concerning COVID trend shows no sign of abating
The new face mask mandate went into effect in Los Angeles County at 11:59 p.m. Saturday. It requires everyone to wear masks in indoor public spaces regardless of their vaccination status.
"Given the increased intermingling among unmasked people where vaccination status is unknown, the millions of people still unvaccinated, and the increased circulation of the highly transmissible Delta variant, we are seeing a rapid increase in COVID-19 infection,'' County Public Health Director Barbara Ferrer said.
