Who Should Get Tested?

People that Have Not Been Fully Vaccinated

If you have not been fully vaccinated, you should get tested if:

  • 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. Click here to view a symptom comparison chart.

  • You are participating in activities that put yourself or others at higher risk for COVID-19 exposure. Non-vaccinated people should 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.

  • You may have been exposed to COVID-19, even if they have no symptoms. Exposure includes being closer than six feet to someone with COVID-19, especially indoors or for more than 15 minutes. Living in the same household or working closely with someone with COVID-19 can increase the risk of getting COVID-19.​

  • 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 3 to 5 days afterward.

  • 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. Click here for more information from the CDC.

  • 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.

Fully Vaccinated People

If you have been fully vaccinated (two weeks after receiving a single-dose vaccine or two weeks after receiving the second dose in a two-dose series):

  • You have COVID-19 symptoms. Symptoms 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. Click here to view a symptom comparison chart.

  • You live or work in a group setting and are exposed to someone with COVID-19. If you live or work in a group setting (like a correctional or detention facility or group home) and are around someone who has COVID-19, you should still stay away from others for 14 days and get tested, even if you don’t have symptoms.

  • International travel: You do NOT need to get tested before leaving the United States unless your destination requires it. You still need to show a negative test result or documentation of recovery from COVID-19 before boarding a flight to the United States, but you do not need to self-quarantine after arriving in the United States. However, you should self-monitor for COVD-19 symptoms and isolate and get tested if you develop symptoms.





When Should You Get Tested?

  • You should also get tested if you have come into close contact with someone who had COVID-19 or you think you have been exposed. A test about three to five days after exposure will identify most COVID-19 infections. However, a negative test at five days does not mean you cannot become infectious later. You can develop symptoms anytime from two to 14 days after being exposed to the virus and may be infections before developing symptoms. Some people never develop symptoms.

  • If you think you have been exposed, you should continue to quarantine at home after you get tested. Get tested again in about five days to be sure you don’t unknowingly spread the virus.

  • We encourage everyone who is not fully vaccinated to consider regular testing. People can still spread the virus even if they do not have symptoms, so the earlier we can detect COVID-19 and those infected can begin to quarantine, the more we can prevent the spread of COVID-19 in our communities.

  • Take steps to help prevent spread, including staying home, practicing physical distancing, wearing a cloth face covering, washing hands frequently, and regularly cleaning high-touch surfaces.


  • Quarantine at home for 10 days if you had close contact with someone with COVID-19, even if you have no symptoms.

  • Get medical help right away if you start feeling sicker, especially if you have trouble breathing, persistent chest pain, begin to feel confused, cannot stay awake, or develop bluish lips or face.


  • Call your health provider if your symptoms do not get better in a few days. Tell them you got tested for COVID-19.  If you do not have a healthcare provider, call the Contra Costa Health Advice Nurse at 1-877-661-6230, option 1.


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.
