Prevent a Winter COVID-19 Surge

Between Thanksgiving and mid-December, the statewide seven day average case rate increased by almost half (47%) and hospitalizations 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 issued updated guidance to curb the spread of COVID-19 and its variants.

As of 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.
