The COVID-19 vaccines remain effective in preventing serious disease, hospitalization, and death from the SARS-CoV-2 virus. Unvaccinated persons are more likely to get infected and spread the virus which is transmitted through the air and concentrates indoors. To ensure that we collectively protect the health and well-being of all Californians; keep schools open for in-person instruction; and allow California’s economy to remain open and thrive, the California Department of Public Health (CDPH) is requiring masks to be worn in all indoor public settings, irrespective of vaccine status from December 15, 2021, through February 15, 2022.
Masks are required for all individuals in all indoor public settings, regardless of vaccination status from December 15, 2021, through February 15, 2022 (surgical masks or higher-level respirators are recommended).
See State Health Officer Order, issued on July 26, 2021, for a full list of high-risk congregate and other healthcare settings where surgical masks are required for unvaccinated workers and recommendations for respirator use for unvaccinated workers in healthcare and long-term care facilities in situations or settings not covered by Cal OSHA ETS or ATD.
For additional information on types of masks, the most effective masks, and ensuring a well-fitted mask, individuals should refer to CDPH Get the Most out of Masking and see CDPH Masking Guidance Frequently Asked Questions for more information.
