Dr. Muntu Davis, public health officer for Los Angeles County, called the return to masks “an all-hands-on-deck moment.” Since California reopened on June 15, the Delta variant of COVID-10 has sparked a marked increase, mostly among unvaccinated people. The county has been recording over 1,000 new cases each day for a week. People will still be able to go maskless while eating or drinking in restaurants. The change does not affect Orange County, but local rates of confirmed new infections in the OC have risen in recent weeks, from around 50 a day to triple that. Additionally, the University of California announced on Thursday that students, staff and faculty must get vaccinated before returning in the fall. According to the Los Angeles Times, new cases of coronavirus in California are up 175 percent over the past 14 days, and deaths by 32 percent.
