9/23/22—As the COVID-19 case rate in Los Angeles County has dropped in community-level transmission, the Los Angeles County Department of Public Health has revised guidelines on mask requirements and recommendations.
Masks are required in health care settings (including the Engemann and Eric Cohen student health centers, COVID-19 testing sites, the USC Herman Ostrow School of Dentistry, USC Pharmacies, and other patient care settings on campus). They are also required for individuals who have COVID-19 (through day 10), or have had close contact with someone who has COVID-19 (for 10 days following exposure).
Masks are strongly recommended on all forms of public transit, including trains, buses, shuttle buses, and ride-shares.
Masks are an individual preference in all other indoor public settings.
