Infected or Exposed to COVID-19?

Regardless of vaccination status, you should isolate from others when you have COVID-19 or if you have symptoms and think you might COVID-19, but do not yet have test results. 

If your results are negative, you can end your isolation. If your results are positive, follow recommendations below.


How Isolation is Calculated

When you can leave Isolation

If you had no symptoms

Day 0 is the day you were tested (not the day you received your positive test result).

Day 1 is the first full day following the day you were tested.

If you develop symptoms within 10 days of when you were tested, the clock restarts at day 0 on the day of symptom onset.

If you have no symptoms - you may end after day 5 (on day 6). 

Wear a well fitted mask around others for Days 6-10. If you are unable or unwilling to wear a mask on Days 6-10, you can use the CDC’s test based strategy that includes two negative tests 48 hours apart.

If you had symptoms

Day 0 is the day of when symptoms started, regardless of when you tested positive

Day 1 is the first full day after the day your symptoms started

If you have symptoms - you may end after day 5 (on day 6) if:

  • You are fever-free for 24 hours (without the use of fever-reducing medication)
  • Your symptoms are improving
  • You wear a well fitted mask around others for Days 6-10. If you are unable or unwilling to wear a mask on Days 6-10, you can use the CDC’s test based strategy that includes two negative tests 48 hours apart. 

If you still have fever or your other symptoms have not improved, continue to isolate until they improve.

If you had moderate illness  (if you experienced shortness of breath or had difficulty breathing), or severe illness   (you were hospitalized) due to COVID-19, or you have a weakened immune system, you need to isolate through day 10.

If you had severe illness  or have a weakened immune system, consult your doctor before ending isolation. Ending isolation without a viral test may not be an option for you.

If you are unsure if your symptoms are moderate or severe or if you have a weakened immune system, talk to a healthcare provider for further guidance.

Note: This is intended for members of the general public. It does NOT apply to healthcare facilities or high-risk congregate settings.

Isolation Guidance

If you test positive for COVID-19, you should stay home for at least 5 days and wear a mask for 10 days after testing positive with COVID-19. 

If you are at higher risk of getting very sick, contact your healthcare provider to see if you are eligible for treatmentEarly treatment can prevent you from getting sicker.

If you were exposed to the virus that causes COVID-19, regardless of your vaccination status or if you have had a previous infection, here are the steps that you should take:

Take Precautions

Watch for symptoms. If you develop symptoms, isolate immediately and get tested.

Wearing a mask for 10 days after exposure may help reduce the risk of spreading COVID-19 to others. You may choose to wear a mask around other people, particularly those who are more likely to get very sick from COVID-19. Consider wearing a mask when around others inside in your home or indoors in public through the end of day 10.

  • Day 0 is the day of your last exposure to someone with COVID-19.
  • Day 1 is the first full day after your last exposure.

Get Tested

If you choose to, get tested on day 6 after your last exposure.

If you already had COVID-19 within the past 90 days, see specific testing recommendations.

Note: This is intended for members of the general public. It does NOT apply to healthcare facilities or high-risk congregate settings.

Exposure risks

Learning about how COVID-19 spreads and the factors that can increase or decrease that risk can help you make informed choices. These factors include:

  • Length of time: how longer were you around the infected person?
  • Coughing or heavy breathing: was the infected person coughing, singing, shouting, or breathing heavily?
  • Symptoms: Did the infected person have symptoms at the time?
  • Masks: Were you or the infected person or both wearing a respirator (for example, N95) or high-quality mask?
  • Ventilation and filtration: How well-ventilated was the space?
  • Distance: How close was the infected person to you?

While Waiting for Test Results

You should stay home and away from others while you are waiting for your test results. This helps protect your friends, family and others from possibly getting COVID-19 from you.

Airplane iconGuidance for travelers

COVID-19 is still spreading within Virginia, across the United States, and in other countries. 

Make sure you are up to date with your COVID-19 vaccines before travel.

Check your destination’s COVID-19 situation before traveling. State, tribal, local, territorial, and other countries' governments may have travel restrictions and requirements in place. Prepare to be flexible during your trip as restrictions and policies may change during your travel.

Wearing a mask over your nose and mouth is recommended in indoor areas of public transportation (including airplanes) and indoors in U.S. transportation hubs (including airports).
