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 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. We recommend getting tested before traveling and 3 to 5 days afterward.
     

  • You are a public-facing essential worker. Essential workers are encouraged to get tested at least monthly, even if they 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 should still get tested if 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.
     

  • Exposure to someone with COVID-19:

    • If you’ve been around someone who has COVID-19, you do not need to stay away from others or get tested unless you have symptoms.

    • However, 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.
       

  • Domestic travel: If you’re traveling within in the United States, you do not need to get tested before or after travel.
     

  • 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.

    • You should still get tested 3-5 days after international travel.

    • You do NOT need to self-quarantine after arriving in the United States.

 

 

 

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.

​​

  • 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.
