Guidance for suspected or confirmed cases - 10/21/2021
Positive Case Reporting
Reporte de casos positivos
CCHS strongly recommends employers allow those who have tested positive for COVID-19 to return to work 10 days after symptom onset. If the employee did not have symptoms, we advise return to work 10 days after their first positive test. We do not advise requiring a negative test to return to work after quarantine has been completed. We also do not provide clearance letters for people to return to work. Notes from doctors or medical providers are also not advised.
All people in Contra Costa County must wear a mask indoors, regardless of vaccination status. Masks are not required in some indoor settings where everyone is fully vaccinated and other safety measures are followed. Click here for more details.
Proof of Vaccination or Negative Test for High-Risk Indoor Businesses:
Everyone 12 years and older must show proof of full COVID-19 vaccination, or a negative test result, before going to high-risk indoor businesses such as restaurants, bars, and gyms in Contra Costa County. Workers at these businesses must be fully vaccinated or test weekly. Click to read more and for tools for businesses.
Physical Distancing and Capacity Limits:
There are no physical distancing or capacity limits for businesses and activities. Most businesses are required to maintain compliance with California’s COVID-19 Prevention Emergency Temporary Standards (ETS), which include current public health guidelines. Certain workplaces, like hospitals and correctional facilities, are required to comply with the Aerosol Transmissible Diseases (ATD) standard instead of the ETS. Find more details in the frequently asked questions about the COVID-19 Prevention ETS.
Nothing prevents employers from implementing additional protective measures than are required by Cal/OSHA. Contra Costa County’s Health Officer also strongly recommends that businesses consider further protective measures, especially with cases rising again because of the Delta variant:
Require employees who come into the workplace to be vaccinated. Employers are legally allowed to require vaccination as a condition of employment, with very limited exceptions for medical exemptions or strongly held religious beliefs.
Requiring documentation of COVID-19 vaccination rather than self-attestation.
Require frequent testing for employees who are unvaccinated.
