How does testing work?

When to Get Tested

People who are not Up-To-Date on Their COVID-19 Vaccination:

If you are not fully vaccinated or have not gotten a booster despite being eligible, testing is recommended in the following situations:

  • You have COVID-19 symptoms, which could include: fever or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting and diarrhea. We recommend getting tested as soon as possible if you are experiencing COVID-19 symptoms. Click here to view a symptom comparison chart.

  • You were or may have been exposed to someone with COVID-19. Exposure includes being closer than six feet to someone with COVID-19, especially indoors or for more than 15 minutes. Get tested 5 days after exposure, or sooner if you start feeling sick. Visit our For COVID-19 Patients and Contacts page for more information.

  • You are participating in activities that put yourself or others at higher risk for COVID-19 exposure. Get tested before traveling, attending large indoor social or mass gatherings (such as large private events, live performance events, sporting events, or theme parks), competing in high-risk sports, or other events in crowded or poorly-ventilated settings. Click to learn more about testing requirements for mega-events.

  • You are planning to attend or have attended a large and/or indoor gathering. Weddings, large religious events especially with singing, funerals and family gatherings have all been “super spreader” events. ​If you do choose to attend a larger gathering or event and aren't yet vaccinated, we recommend getting tested before the event and 5 days after.

  • You are planning to travel or have traveled, especially for a long distance, on a plane, train or other mode of transportation. Get tested with a viral test 1-3 days before your travel. Get tested with a viral test 3-5 days after travel AND stay home and self-quarantine for a full 7 days after travel. If you don’t get tested after travel, self-quarantine for 10 days. Follow CDC recommendations for domestic travel and international travel.

  • You are regularly in contact with the general public (i.e. you work in health care, retail, food services, transportation or schools). We recommend getting tested at least monthly, even if you have no symptoms or no known exposure to someone who has tested positive for COVID-19. If you work in some high-risk settings, such as healthcare facilities or a detention or group home, you are required to get tested every week. Follow the instructions from your workplace.

  • You are going to a high-risk indoor business, such as a restaurant, bar, or fitness facility. Everyone 12 years and older must show proof of full COVID-19 vaccination, or a negative test result from a test taken in the past three days, 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 here for more information.

  • You are visiting a hospital or nursing home in California. Visitors to hospitals must show proof of vaccination for COVID-19 or a negative COVID-19 test result. Visitors to nursing homes must be fully vaccinated and boosted if eligible AND show a negative COVID-19 test result. Click for more information, including full requirements and a list of exceptions, informational flyer and Q&As.


People who are Up-To-Date on Their COVID-19 Vaccinations

If you have gotten a booster or are not yet eligible for a booster, testing is recommended in the following situations:

  • To end isolation. If you test positive for COVID-19, you can end your isolation period on day 6 if a test taken on or after day 5 is negative. Antigen tests are recommended for COVID-positive people to end isolation. Visit our For COVID-19 Patients and Contacts page for more information.

  • You came into close contact with someone with COVID-19. Close contact means being closer than six feet to someone with COVID-19, especially indoors or for more than 15 minutes. Get tested 5 days after close contact with a person with suspected or confirmed COVID-19. If you start to feel sick, quarantine at home and get tested right away. Visit our For COVID-19 Patients and Contacts page for more information.

  • Travel: Follow CDC recommendations for domestic travel and international travel. All people, whether they’re vaccinated or not, should get tested within 3-5 days of arriving in California.

Why Does Testing Matter?

Widespread testing provides a more accurate picture of how many cases exist in our community and helps us understand how and where the virus is spreading. This helps us make decisions that keep us all safe.


Testing also helps identify people without symptoms who could be spreading COVID-19. For each person we contact, we check symptoms, offer testing and recommend avoiding close contact with other people until it’s safe to do so. Click to learn more about contact tracing.
