SACRAMENTO, Calif. (KTXL) — The Sacramento County Public Health Officer has issued a new health order requiring masks to be worn indoors regardless of vaccination status. 

County health officials said the change in requirements comes after “continued day-over-day rate increases of the highly infectious delta variant.”

The order takes effect Friday.

June 24, Sacramento County’s daily COVID-19 case rate was 5.2, officials said. July 20, that number rose to 18.3.

Masks are required in all indoor public settings including venues, gatherings, workplaces, offices, retail stores, restaurants, bars, theaters, entertainment centers and state and local government offices. 

Only 49% of Sacramento County’s population is fully vaccinated against COVID-19.
