More Than 80% of Alameda County Residents are Now Fully Vaccinated - issued January 13, 2022

Alameda County Public Health Department announced that more than 1.3 million Alameda County residents are fully vaccinated against COVID-19.  At this milestone, 80.2 percent of all residents are fully vaccinated; over 86.5 percent have had at least one dose; and 49.2 percent of all eligible have received a booster. Seventy-one percent of Hispanic/Latino/a/x and 69.3 percent of Black/African American Alameda County residents have received at least one dose of a COVID-19 vaccine, and residents are strongly encouraged to get their second doses and boosters for best protection against serious illness or hospitalization.  Alameda County prioritized resources to the communities where these disparities were occurring and resulting in disproportionate impacts. This strategy is reflected in community testing; case investigation and contact tracing; resources to support isolation and quarantine; vaccination; and now supporting community coalitions.  Residents are asked to remain vigilant and take steps to lower the risk of transmitting COVID-19 including:

• Keep gatherings small, short and, if possible, outdoors. 

• When gathering inside, ventilate well. Open doors and windows, run HVAC systems and install highquality air filters.  

• Everyone must wear a mask in indoor public settings.  Consider wearing a mask in indoor private settings if gathering with medically vulnerable friends and family or if someone’s vaccination status is unknown. 

• If possible, get tested to know your COVID-19 status before gathering with friends and family.  Plan to test 3-5 days after gathering or traveling too.  

• Stay home if sick or tested positive, even if an at-home test is used. 

Weekly COVID Testing Site at Dublin Senior Center Now Requiring Appointments - issued January 6, 2022

Due to the recent high demand for COVID-19 testing, the Curative mobile testing site, which is open Wednesdays, 8:00 a.m. to 1:30 p.m., at the Dublin Senior Center, is now requiring appointments.  Previously, the testing site handled approximately 35-40 tests per week.  In recent weeks, upwards of 200 people have requested tests each day, and staff is unable to handle this volume.  Those seeking a COVID test can visit to book an appointment.  If it is difficult to find an appointment through Curative, some additional options include: and

Alameda County Health Officer Rescinds Previous Order: Everyone Must Wear Masks Indoors - issued December 29, 2021

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.

Alameda County's Local Face Covering Order Remains in Effect - issued December 15, 2021

Per the State of California's recent health order regarding face masks, Alameda County Public Health Department reports that its face covering order remains in effect.  Residents will not experience any differences in policy. Everyone aged two and older, regardless of vaccination status, is required to wear a mask in indoor public settings, with a limited exemption for certain controlled settings with a small, stable group of fully vaccinated people.  With vaccinations and boosters, masks are one of the best tools available to prevent spreading COVID-19 to family, friends, and community members.

Alameda County Health Officials Strongly Recommend COVID Vaccine Boosters for All Adults - issued November 18, 2021

The Centers for Disease Control and Prevention (CDC) strongly recommended today COVID-19 boosters for all adults who have been fully vaccinated with the COVID-19 Pfizer or Moderna vaccines at least six months ago. People can choose a different COVID-19 vaccine than their original series as a booster.  The CDC previously recommended a booster for all adults who received the Johnson & Johnson vaccine at least two months ago.

As there is emerging evidence that immunity from the COVID-19 vaccine may wane over time, it is recommended that adults should get their booster now, if eligible.  The Alameda County Public Health Officer, Dr. Nicholas Moss, indicated that a rise in COVID-19 cases is expected "as people gather with friends and family indoors and travel for the holidays." 

The Pfizer and Johnson & Johnson booster doses are the same dosage as the original vaccine received in the series, while the Moderna booster dose is half the dosage of the original vaccine series.  A person can receive their booster from any location, not necessarily where they received their initial vaccine series.  Booster appointments are also available through

Alameda County to Ease Masking Requirements for Fully Vaccinated People in Limited Indoor Settings - issued October 28, 2021

Beginning November 1, the County of Alameda will begin to ease masking requirements in certain indoor settings where everyone is fully vaccinated.  Eligible settings are in controlled spaces not open to the general public, including offices; gyms and fitness centers; employee commuter vehicles; and organized indoor gatherings where a group meets on a regular basis, such as religious gatherings.

Under the Health Officer Order, participating businesses, organizations, or hosts must verify that all patrons, employees, and attendees are fully vaccinated before allowing people to go unmasked inside their facilities.  Additionally, there can be no more than 100 people present at these facilities, and those present cannot have COVID-19 symptoms.  Employers or hosts must be shown proof of one's vaccination status, and identities must be confirmed with government-issued identifications, such as a driver's license or passport.

Indoor masking requirements will remain in effect in other public settings, such as bars, restaurants, and retail establishments, and in indoor K-12 school settings.  Businesses and workplaces can continue to require indoor masking of everyone in these non-public places if they choose, and employees and patrons can choose to wear a mask indoors if they prefer. 

The State of California continues to require face coverings for all unvaccinated persons in indoor public settings, and for everyone, regardless of vaccination status, in health care facilities, on public transit, and in adult and senior care facilties.

CDC Recommends COVID-19 Vaccine Boosters for Older Adults and Certain Groups - issued October 22, 2021

The Centers for Disease Control (CDC) is now recommending that adults over the age of 65 and other groups who received initial doses of the COVID-19 vaccine should get a booster shot.  

As recent evidence suggests that immunity from the COVID-19 vaccination may wane over time, booster doses are recommended for older adults and younger people with underlying conditions or certain risk factors who received the Pfizer or Moderna vaccine more than six months ago, and anyone who received the one-shot Johnson & Johnson vaccine at least two months ago.  Health officials are now permitting the "mixing and matching" of vaccines, so recipients may choose a different COVID-19 vaccine than their original shot.

A single COVID-19 vaccine booster shot is now recommended if you completed a Pfizer or Moderna (mRNA) vaccination series six or more months ago and you are:

  • Aged 65 or older or
  • A long-term care resident that is aged 18 or older, or
  • Aged 50-64 and have an underlying medical condition, or 
  • Aged 50-64 and at an increased risk due to poverty or lack of healthcare access

Boosters should also be considered if you are:

  • Aged 18-49 and have an underlying medical condition or are at risk due to poverty or lack of healthcare access or 
  • Aged 18-49 and work or live in a high-risk setting, such as a shelter

The booster dose for the Moderna vaccine is one-half the dose used for the initial series.  Booster doses are also recommended for anyone aged 18 and older who received the one-shot Johnson & Johnson vaccine.

Any eligible person seeking a booster shot should consult with their medical provider or access the booster through a chain pharmacy.  Visit for more information.

Bay Area Health Officers Issue Criteria for Lifting COVID-19 Indoor Masking Requirements - issued October 7, 2021

Bay Area health officers announced today that indoor masking requirements in public spaces may soon be lifted if certain criteria within jurisdictions are met.  (The City of Dublin's jurisdiction is Alameda County.)

  • The jurisdiction (Alameda County) reaches the moderate (yellow) tier, according to the Centers for Disease Control and Prevention, and remains at that level for three weeks;
  • Hospitalizations due to COVID-19 remain low and stable;
  • Eighty percent of the jurisdiction's (Alameda County's) total population is fully vaccinated with two doses of Pfizer or Moderna or one dose of Johnson & Johnson; OR eight weeks have passed since a COVID-19 vaccine has been authorized for emergency use by federal and state authorities for five- to 11-year-olds.

Approval of the vaccine for five- to 11-year-olds is anticipated sometime between Halloween and Thanksgiving. Under this framework, it is possible that the indoor mask mandate will remain in place through the end of the year.

Bay Area Jurisdictions Extend Stay-at-Home Order Through January 7, 2021 - issued December 16, 2020

Due to I.C.U. capacity falling below the 15-percent threshold in the Bay Area Region, Alameda County and seven other Bay Area jurisdictions have extended the most recent Stay-at-Home Order through January 7, 2021.  However, because the County's restrictions already align with the State of California's restrictions, no additional changes have been made to the Order.

If, after three weeks, the ICU capacity meets or exceeds the 15-percent threshold, the Order could be lifted.  Alameda County reports that the week ending on December 12 was the worst week of the pandemic so far in the County, with 5,000 new COVID cases reported.  All residents are asked to stay at home as much as possible, avoid all gatherings, and wear a mask when it becomes necessary to leave home.

Alameda County to Adopt State's Regional Stay-at-Home Restrictions Beginning Monday, December 7 - issued December 4

Alameda County Public Health announced today that the County, along with other Bay Area jurisdictions, will adopt the State of California's Regional Stay-at-Home framework, beginning Monday, December 7, at 12:01 a.m., through Monday, January 4, 2021.  During this time, all private gatherings and non-essential travel are prohibited.

The area Public Health Officers believe that this early action is needed because the number of new cases is rising rapidly in the region, and more cases are expected as a result of Thanksgiving gatherings.  Hospitalizations are already matching the peak seen during the summer and there is a high risk of exhausting the system's capacity.  This is a regional issue because hospitals provide overflow capacity for neighboring jurisdictions, and our neighboring counties have seen rapid increases in the past two weeks.

During this time, all private gatherings and non-essential travel are prohibited and the following activities are restricted:

  • K-12 Schools - Only schools that are currently offering in-person learning may continue to be open.
  • Non-urgent Medical and Dental Care - Open, with modifications.
  • Childcare and Pre-K - Open, with modifications.
  • Stand-alone Grocery Stores - Permitted indoors at 35% capacity with entrance metering.  Eating and drinking are prohibited in stores, and masks are required to be worn.  Special hours must be made available for seniors and those with chronic conditions or compromised immune systems.
  • Retail and Shopping Centers - Permitted indoors at 20% capacity with entrance metering.  Eating and drinking are prohibited in stores, and masks are required to be worn.  Special hours must be made available for seniors and those with chronic conditions or compromised immune systems.
  • Restaurants - Take-out and delivery, only.
  • Hotels and Lodging - Open for critical infrastructure support, only.
  • Offices - Remote work, only, except for critical infrastructure sectors where remote working is not possible.
  • Indoor Playgrounds - Closed.   Order amended on December 9 to allow for outdoor playgrounds to be open.
  • Indoor Recreational Facilities - Closed, except for indoor pools which teach drowning prevention classes, including swim lessons with certified instructors. 
  • Hair Salons/Barbershops - Closed
  • Personal Care Services - Closed
  • Limited Services - Closed, unless identified as Critical Infrastructure per State of California.  Those deemed non-essential, including shoe repair, pet groomers, and dog walkers, can be open with curbside pickup and drop-off only.
  • Museums, Zoos, and Aquariums - Closed
  • Wineries - Closed
  • Bars, Breweries, and Distilleries - Closed
  • Family Entertainment Facilities - Closed
  • Amusement Parks - Closed
  • Cardrooms and Satellite Wagering - Closed
