Alameda County Health Officer Rescinds Previous Order: Everyone Must Wear Masks Indoors

The Alameda County Health Officer, Dr. Nicholas Moss, has rescinded a previous health order allowing fully vaccinated people to go unmasked in certain settings.  Effective December 30, everyone, regardless of vaccination status, must wear masks in all indoor public settings.  This change will not affect face masking requirements for youth and school settings.

The local daily case rate in Alameda County is 18.7 per 100,000 residents and rising, and community transmission is now categorized as “high” on the CDC’s COVID-19 data tracker. The Omicron variant of the virus that causes COVID-19 is highly transmissible.  Wearing masks in all indoor public settings will help limit the spread of COVID-19 and protect vulnerable residents this winter.  

With the Omicron variant able to spread among fully vaccinated people and those who have already had the coronavirus, Dr. Moss says that masks are "a critical layer of safety for everyone this winter."  Vaccination and booster doses, together with masking, will protect residents and keep hospitals from being overwhelmed with people who are severely ill due to COVID.

Alameda County Public Health Department recommends:

  • Getting vaccinated, and if already vaccinated, getting the vaccine booster shot;
  • Staying home if COVID-positive, symptomatic, or unvaccinated, not boosted, and exposed;
  • Wearing a mask in all indoor public settings; 
  • Getting tested if exposed, symptomatic, or before and after gathering and traveling; 
  • Avoiding large or crowded and poorly ventilated settings.
