Alameda County Lifts Indoor Mask Mandate as COVID-19 Case Rates Improve - June 24, 2022

Alameda County Public Health Department officials announced today that the most recent indoor mask mandate is being rescinded, effective 12:01 a.m., on June 25, 2022.  Masks will continue to be required, however, in public health settings; congregate settings such as homeless shelters and correctional facilities; and long-term care facilities.     

Daily reported COVID-19 cases have peaked and continue to decline, and case rates are improving across each of the County’s largest racial and ethnic groups, including Hispanic/Latino residents, who were disproportionately affected. 

Businesses, venue operators, and hosts may choose to continue requiring patrons and workers to wear masks to lower COVID-19 risk in their settings. 

Alameda County is also aligning with the State’s quarantine guidance and definition of close contact, effective 12:01 a.m., on Wednesday, June 29, 2022. People who are close contacts but don’t have symptoms should test within 3-5 days after last exposure and wear a well-fitting mask around others for a total of 10 days, especially in indoor settings and when near those at higher risk for severe COVID-19 disease. Anyone who develops symptoms should test immediately and stay home. Anyone who tests positive must follow isolation requirements. 

Health officials also stated, "Vaccination continues to provide the best long-term protection against serious COVID-19 disease. Everyone six months and older is now eligible for safe, effective COVID-19 vaccines."

Alameda County to Require Masking Again in Most Public Places - June 2, 2022

Due to a recent increase in COVID-19 hospitalizations, Alameda County public health officials have announced that masks will be required in most public settings beginning Friday, June 3. While masking will not be required through the end of the 2021-22 school year, masking will be required in all other children and youth indoor settings, including childcare, summer school, and youth programs, as is feasible.  

Alameda County reports that daily COVID-19 cases have exceeded the peak of last summer's Delta wave and are approaching levels seen during the Winter 2020-21 wave. Hospitalizations are also on the rise.  Alameda County Public Health Officer Dr. Nicholas Moss said, "Putting our masks back on gives us the best opportunity to limit the impact of a prolonged wave on our communities." Children under the age of two should not mask.

In addition to masking, residents are reminded to continue to take other precautions to limit the spread of COVID-19.  Stay home if sick or positive; test if symptomatic or exposed; and keep gatherings small and outdoors, if possible.  Increase ventilation if gathering indoors.

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.

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 Announces Plans for Initial COVID-19 Vaccine Distribution - December 14, 2020

Alameda County Public Health Department has announced that it expects to receive its initial supply of the Pfizer COVID-19 vaccine as early as December 15.  The first shipment, containing 12,675 doses, will be distributed to frontline hospital workers and 9-1-1 first responders, as they are at the highest risk of exposure to COVID-19.  Residents and staff at long-term care facilities will be next to receive the vaccine.  Additional doses of the vaccine are expected in the coming weeks.

Phase Two of vaccine distribution would go to essential and critical infrastructure workers; older adults; people with underlying health conditions; and those in jail or prison or living in other group settings. Phase Three will be distributed to children, young adults, and people working in lower risk settings.  Phase Four will include those not in the first three phases. 

The County's vaccine planning includes community education and engagement; health care systems coordination; and immunization logistics for the coordination of distribution.

Outdoor Playgrounds Now Open Again for Use - December 9, 2020

The State of California has reversed its health order regarding the use of outdoor playgrounds. While indoor playgrounds and recreation sites remain closed, outdoor playgrounds will be re-opened, but visitors must comply with certain requirements:

  • Face masks worn over the mouth and nose are required for everyone two years of age or older, with caregiver supervision at all times to ensure face mask use.
  • Do not use the playground when different households are unable to maintain a physical distance of six feet or when the capacity limit has been reached.
  • Caregivers must monitor to keep adults and children from different households at least six feet apart.
  • Families should consider visiting playgrounds on different times or days to avoid wait times and potentially crowded areas.
  • No eating or drinking is allowed in playground area, in order to ensure face masks are worn at all times.
  • Wash or sanitize hands before and after using the playground.
  • Elderly persons or those with underlying medical conditions should avoid playgrounds when others are present.
  • Limit visit to 30 minutes per day when others are present.

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
