This past Friday, the Health Officers from Alameda County and several other Bay Area counties issued a recommendation for ALL residents - including those who are fully vaccinated - to wear masks in indoor public settings. This recommendation comes as case rates in Alameda County are rising and the highly infectious Delta variant of the virus is circulating across the state and country.

This recommended safety measure is consistent with Alameda County's current guidance regarding workplace COVID-19 safety protocols as detailed in the countywide announcement issued on June 11, 2021. Universal masking indoors helps us comply with State requirements for workplaces and ensure that all unvaccinated employees are masked indoors, and also serves as an extra precautionary measure for all employees and visitors.

Vaccinating as many people as possible, as quickly as possible, is the best defense against severe COVID-19 infection and fully-vaccinated people are well-protected against infections and serious illness due to known variants. After vaccination, masking is the next most powerful tool available to protect ourselves and each other.

If you are already vaccinated, thank you. If you are interested in learning more about the COVID-19 vaccines or where you can find a vaccination site, please visit As health officials continue to monitor data and disease trends over the coming weeks, please remember to mask-up at work and to wear a mask when you are out in your community.

We appreciate each and every one of our valued County employees for working safely and productively in the midst of the many challenging conditions presented by the global pandemic. Thank you all for your ongoing efforts to help prevent the spread of COVID-19 and help save lives.
