Self-Isolation Instructions for Confirmed COVID-19 Cases

People with a positive COVID-19 test result need to isolate. After you test positive, you will receive a virtual automated survey from Contra Costa Health Services asking for information, such as places you’ve been or people you’ve spent time with. The survey will offer you an option to enroll in a text message virtual assistant program that will check on you and provide resources during your isolation. In some cases, you may be contacted by our contact tracing team if you were at school, work or in a congregate-care facility while infectious.

Unvaccinated: People who are not fully vaccinated and who have been identified as being in close contact with, or think they may have been in close contact with someone that has COVID-19, need to quarantine. Get tested right away and again 5-7 days later, or sooner if you start to feel sick.

 

Fully vaccinated: You should get tested 5-7 days after exposure to someone who has or might have COVID-19. If you are fully vaccinated, you do not need to quarantine unless you develop symptoms of COVID-19. Quarantine Guidance for Vaccinated Persons​.
