State officials have announced the return of a statewide indoor mask mandate for all California residents beginning tomorrow, December 15. The mandate comes following a sharp increase in COVID-19 infection rates since Thanksgiving and will remain in place until January 15. The state will also require unvaccinated people attending “mega-events” of over 1,00 people to show proof of a negative coronavirus test result from within a day, if it’s an antigen test, and within two days for a P.C.R. test, and formally recommended that travelers returning to California get tested within a few days of their arrival.
