With case rates increasing 47% since Thanksgiving, the California Department of Public Health will require universal masking to increase protection to individuals, families, and communities during the holidays.

SACRAMENTO –The California Department of Public Health (CDPH) continues to monitor COVID-19 data in order to protect the health and well-being of all Californians. Since Thanksgiving, the statewide seven-day average case rate has increased by almost half (47%) and hospitalizations have increased by 14%. In response to the increase in cases and hospitalizations, and to slow the spread of both Delta and the highly transmissible Omicron variant, CDPH has issued updated guidance to curb the spread of COVID-19 and its variants. 

Beginning December 15, CDPH will require masks to be worn in all indoor public settings irrespective of vaccine status through January 15, 2022, at which point California will make further recommendations as needed in response to the pandemic. 

Additionally, CDPH updated requirements for attending mega events, like concerts and sporting events. Prior to attending an event, attendees will now require either proof of vaccination, a negative antigen COVID-19 test within one day of the event, or a negative PCR test within two days of the event.

CDPH also issued a new travel advisory effective immediately to recommend that all travelers arriving in California test for COVID-19 within three to five days after arrival, regardless of their vaccination status.  

"Our collective actions can save lives this holiday season. We are already seeing a higher level of transmission this winter and it is important to act now to prevent overwhelming our busy hospitals so we can provide quality health care to all Californians. All Californians should get vaccinated and receive their booster. Getting your whole family up to date on vaccination is the most important action you can take to get through the pandemic and to protect yourself from serious impacts from the virus and its variants. Testing and masking remain important tools in slowing the spread," said Dr. Tomás J. Aragón, CDPH Director and State Public Health Officer. "Starting Wednesday, California will require masking in all public indoor places during the holiday season regardless of vaccination status. Attendees of large events will be required to show either proof of vaccination, a negative antigen COVID-19 test within one day of the event, or a negative PCR test within two days of the event. Additionally, California has issued a travel alert to recommend that all travelers get tested within three to five days of their arrival in California. Vaccines and these temporary measures will allow friends and families to safely spend the holidays together and will add critical layers of protection to keep people safe." 

Omicron Variant

The recent emergence of the Omicron variant emphasizes the importance of getting a vaccine, booster, and taking prevention efforts needed to protect against COVID-19. As of December 12, 2021, 24 confirmed cases associated with the Omicron variant have been reported to the state. This number will be updated weekly with the other variants California is currently monitoring on the CDPH Tracking Variants webpage. For more information about the Omicron variant, see the Omicron variant fact sheet.

Stop the Spread: Get Vaccinated for COVID-19

The risk for COVID-19 exposure and infection continues as a number of Californians remain unvaccinated. Real-world evidence continues to show that the vaccine is preventing severe illness, hospitalization, and death. With the combination of colder weather keeping people indoors, the waning of vaccine and natural immunity, and more mingling among non-household members, public health officials urge Californians to get vaccinated and boosted as soon as possible to help prevent a possible winter surge in COVID-19 cases.

It is recommended that every vaccinated adult 18 years or older should get a booster as long as they received their second dose of the Pfizer or Moderna vaccine at least six months ago or they received their Johnson & Johnson vaccine at least two months ago.

Vaccination appointments can be made by visiting myturn.ca.gov or calling 1-833-422-4255. The consent of a parent or legal guardian may be needed for those under age 18 to receive a vaccination.

Your Actions Save Lives

Protect yourself, family, friends and your community by following these prevention measures:

• Celebrate safely: Take commonsense steps this holiday season to protect yourself, your family and your community as you celebrate the holiday season.
• Upgrade your mask: Good fit and filtration continue to be the best way to get the most out of your mask. The best masks for preventing COVID-19 include the N95, KN95 and KF94. If you don't have access to one of these masks, wear a surgical mask or a surgical mask with a cloth mask on top. If you choose a fabric mask, opt for one with three of more cloth layers. No matter what kind of mask you wear, check the fit by avoiding gaps above the nose or on the sides.
• Get vaccinated for COVID-19 and flu: It's your turn now! It's recommended for everyone over six months of age to be vaccinated for the flu. For COVID-19, Californians age 5+ are eligible to make appointments or go to a walk-in site for vaccination. You can get your flu and COVID-19 vaccines on the same day.
• My Vaccine Record is an easy way to show vaccination status at venues or businesses that require proof of vaccination. Visit myvaccinerecord.cdph.ca.gov today to get your vaccine record.
• Stay Home & Get Tested if Sick: If you are experiencing symptoms of COVID-19 (fever, cough, shortness of breath, fatigue, muscle or body aches), or believe you have been exposed,  get tested, call your health care provider, and stay home and away from others. Free, confidential testing is available statewide. Avoid close contact with people who are sick and stay home from work and school if you feel ill.
• Wash hands with soap and water for at least 20 seconds.
• Travel tips: Delay travel (both domestic and international) until you are fully vaccinated. If you must travel before being fully vaccinated, consider getting tested before and after travel. See the CDC's full travel guidance.
• Avoid crowded venues or areas when cases are high.
• Add your phone to the fight:  Sign up for COVID-19 exposure notifications from CA Notify.
• Answer the call or text if a contact tracer from the CA COVID Team or your local health department tries to connect.
• Check with your local health department about local conditions. Local health jurisdictions can implement protocols that are stricter than state guidance.
