Some Southern California casinos are changing their mask policies to combat a rising COVID-19 infection rate.

Pechanga Resort Casino in the Temecula area is urging that guests who are vaccinated against the novel coronavirus wear face coverings while indoors and requires unvaccinated guests to wear them as of Friday, July 30.

San Manuel Casino in Highland is adopting the same guidance, which goes into effect at 8 a.m. Saturday, July 31, according to a post on its website.
