CDC Quarantine and Isolation Calculator is a tool to help people who have been in close contact with someone with COVID-19 or have COVID-19 to determine if they need to isolate, quarantine, or take other steps to prevent spreading COVID-19.
To use the tool:
- People with COVID-19 who do not have symptoms need to know the date they were tested for COVID-19
- People with COVID-19 who have symptoms need to know the date their symptoms began
- Close contacts need to know the date they last came into close contact with someone with COVID-19
Answers to frequently asked questions about the Quarantine and Isolation Calculator are available for those who want to learn more about the tool.
Recommendations for People with COVID-19
Have you tested positive for COVID-19 or have mild symptoms and are waiting for test results?
Here’s What To Do:
Isolate. Stay at home for at least 5 days.*
To keep others safe in your home, wear a mask, stay in a separate room and use a separate bathroom if you can.
Do not travel for 10 days.
If you can’t wear a mask, stay home and away from other people for 10 days.
To calculate the recommended time frames, day 0 is the day you were tested if you don’t have symptoms, or the date your symptoms started.
Contact your healthcare provider to discuss your test results and available treatment options. Watch for symptoms, especially fever. If you have an emergency warning sign, such as trouble breathing or persistent chest pain or pressure, seek emergency medical care immediately.
Day 6: Do a self-check. How are you feeling?
You could have loss of taste or smell for weeks or months after you feel better. These symptoms should not delay the end of isolation.
No symptoms or symptoms improving.
No fever without fever-reducing medication for 24 hours: You can leave isolation. Keep wearing a mask around other people at home and in public for 5 more days (days 6-10).
Symptoms not improving and/or still have fever: Continue to stay home until 24 hours after your fever stops without using fever-reducing medication and your symptoms have improved.
After you feel completely better, keep wearing a mask around other people at home and in public through day 10.
*If you are moderately or severely ill (including being hospitalized or requiring intensive care or ventilation support) or immunocompromised, please talk to your healthcare provider about when you can end isolation.
