Masks still strongly recommended; vaccines and boosters urged to further strengthen defenses
In alignment with the State, the Bay Area counties of Alameda, Contra Costa, Marin, Monterey,
Napa, San Francisco, San Mateo, Santa Cruz, Solano, Sonoma, and the City of Berkeley will lift
universal mask requirements for most indoor public settings beginning Wednesday, February 16.
Unvaccinated individuals over age 2 will continue to be required to wear masks in all
indoor public settings. Businesses, venue operators and hosts may determine their own paths
forward to protect staff and patrons and may choose to require all patrons to wear masks.
The change aligns with the California Department of Public Health’s (CDPH) decision to let
expire the statewide indoor mask requirement, which was instated on December 15 during the
latest COVID-19 surge. Indoor masking is still required by the State for everyone,
regardless of vaccination status, in public transportation; health care settings; congregate
settings like correctional facilities and homeless shelters; long term care facilities;
and in K-12 schools and childcare settings.
Bay Area health officers, in alignment with CDPH, continue to strongly recommend masks be
used as an effective tool to prevent the spread of the virus especially when case rates are high, or
when additional personal protection is needed. Continuing to mask in indoor public settings,
especially crowded or poorly ventilated spaces, remains the safest choice for an individual and
protects those who are medically vulnerable or are not able to get vaccinated, like our youngest
children. As evidence continues to show, vaccinations and boosters remain the best defense
against the virus.
The highly contagious Omicron variant brought on a new stage of the pandemic with a high
number of new infections, but significantly fewer cases of life-threatening illnesses, especially
for those who are vaccinated and boosted. While relaxing indoor masking requirements is part of
a population-level shift toward a “new normal” of living with the disease, the Health Officers
recognize that essential workers and communities of color continue to be highly impacted by
COVID-19 and will need additional support to limit widening health disparities. Changes to
health orders and recommendations may be updated as Health Officers follow the science and
the data to evaluate whether additional protective measures may be needed as the virus evolves
and if future surges occur.
People should continue to choose layered prevention strategies, such as wearing well-fitted
masks (N95 or double layer cloth over surgical are best); staying home and testing when
symptomatic; testing before gatherings; and improving indoor ventilation in situations where
these strategies can add protection for themselves and others. Staying “up to date” on
vaccinations, meaning primary series and boosters when eligible, remains the most important
way to prevent severe illness, hospitalization, and death.
After reaching a pandemic peak of 267 new cases per 100,000 residents per day on January 10,
Alameda County’s COVID-19 case rate declined to 91 on January 31 and has continued to drop
rapidly. Meanwhile, hospitalizations have decreased 30% from their peak and never exceeded
Alameda County health care facilities’ overall capacity during this latest surge because of the
County’s high vaccination (82%) and booster (58%) rates. Alameda County’s universal mask
mandate has been in place since August 2 when cases began climbing from the Delta variant.
A combination of preventative strategies, which included mask use, vaccination, boosters and
testing, along with the community’s cooperation helped get the Bay Area through this latest
surge together as a stronger community.
“Alameda County residents’ actions—getting vaccinated and boosted, staying home when ill,
and wearing masks—have helped us weather the Omicron storm. Masking will continue to be an
important layer of protection as we move forward and learn to live with COVID,” said Dr.
Nicholas Moss, Alameda County Health Officer. “You should feel comfortable continuing to
wear your mask when you need an additional layer of safety, and confident that you are making
the safest choice for yourself and your loved ones.”
By aligning with the state masking rules, the participating Bay Area counties will not need to
meet previously established criteria for lifting local masking orders, which were devised at a
different point in the pandemic.
CDPH continues to require masking in K-12 school settings but has indicated adjustments to the
state’s policies will be shared in the coming weeks. In the meantime, there is work to be done in
closing the remaining gaps in vaccinations and boosters among children, with a particular focus
on equity gaps within the most highly impacted communities.
For early education programs, such as preschool and childcare settings, CDPH continues to
require masking for children older than age two. Vaccinations for children under 5 are currently
undergoing federal review. Workplaces will continue to follow the COVID-19 prevention
standards set by CalOSHA.
Some people may understandably feel anxious about these changes to masking requirements in
the county. People can continue to choose to wear face coverings around others whether it’s
mandated or not and should respect people’s choices around their health. Community members
who are vaccinated and choose not to mask should respect the choices of those who continue to
mask. Officials ask residents and visitors to be kind and respectful as people evaluate their risks
and make choices to protect themselves and those around them.
Note: San Benito County has confirmed it will also join the Bay Area region lifting mask requirements for
a total of 12 jurisdictions.
