Updated Requirements for Mega Events

CDPH has released updated requirements for attending mega events, such as concerts and sporting events. The new guidance lowers the occupancy threshold of 10,000 attendees to 5,000 for outdoor events, and 1,000 attendees to 500 for indoor events. Venues covered by the requirement must be in full compliance no later than January 15, 2022. Prior to attending an event, attendees are required to provide 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.

Updated Guidance: Visitation at Hospitals and Skilled Nursing Facilities

Today, CDPH updated visitation guidance for hospitals and skilled nursing facilities. See the updated Order of the State Public Health Officer Requirements for Visitors in Acute Health Care and Long-Term Care Settings.

Isolation and Quarantine

CDPH continues to monitor COVID-19 cases and take action to slow transmission in light of the fast-spreading Omicron variant. CDPH updated guidance to align with the recommended isolation and quarantine timeframes from the Centers for Disease Control and Prevention (CDC). In this time of uncertainty due to Omicron, CDPH added additional testing recommendations to exit isolation and quarantine and improved masking measures to protect the health and well-being of all Californians.

Isolation for COVID-19 Positive Individuals

All individuals with COVID-19, regardless of vaccination status, should stay home for at least five days. Isolation can end after day five if symptoms are not present or resolving and if an antigen test collected on day five or later is negative.  

Quarantine for Individuals Exposed to COVID-19

Unvaccinated individuals who are exposed to COVID-19, and vaccinated people who are eligible for a booster but have not yet received a booster who are exposed to COVID-19, should stay home for at least five days and also get an antigen test on day five.

Vaccinated individuals who have received their booster, or are not eligible for a booster, and are exposed to COVID-19 do not have to stay home but should test on day five. 

Omicron Update

Overall, clinical and wastewater data show that Omicron cases are present in most regions of the state, indicating that there is likely community transmission. Mutations consistent with Omicron variant have been detected at increasing proportions in wastewater in multiple regions throughout California where this surveillance is conducted. Data from several sources, including genetic sequencing from COVID-19 patients, wastewater surveillance, and reports from health care partners, indicate that the proportion of cases due to the Omicron variant is increasing rapidly. Additionally, genetic sequencing does not represent real-time data, as sequencing generally occurs several days or more after initial tests are positive for COVID-19. 

The emergence of the Omicron variant emphasizes the importance of taking prevention efforts needed to protect against COVID-19, including getting a vaccine or booster. For information on Omicron and other variants, see the CDPH variant webpage and the Omicron variant fact sheet.

Slow the Spread: Get Vaccinated and Boosted 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 the MyTurn website ( 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. Visit Vaccinate All 58 to learn more about the safe and effective vaccines available for all Californians 5+.

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.

  • Wear your mask: CDPH requires 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. 

  • 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 the Digital COVID-19 Vaccine Record website ( 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. See the CDC's full travel guidance. If you decide to travel, a recent travel advisory recommends that all travelers arriving in California test for COVID-19 within three to five days after arrival, regardless of their vaccination status.

  • 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.
