If you have symptoms:

Symptoms may 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, or diarrhea.


If you test positive:

Using MIT’s campus testing systemUsing your own test or a test from outside of MIT’s campus testing system:
There’s no need to report your positive test result, as it is already in MIT’s system.Report your positive test result in Covid Pass or on Atlas.

For either testing option above:

  1. Isolate for 5 full days after your positive test result or after the onset of symptoms. Start counting on the day of your positive test or symptom onset.
  2. If you have been fever-free for at least 24 hours and any other, remaining symptoms are mild and improving, you may leave isolation after 5 full days.
  3. Continue to wear a mask around others in all settings for an additional 5 days after leaving isolation.
  4. Do not test with MIT’s testing program for 90 days. This CDC recommendation is due to the high rate of non-infectious viral shedding, which MIT’s highly sensitive PCR testing will pick up. If you become symptomatic between your positive test and the 90-day mark, consult with MIT Medical or your regular healthcare provider.

How do I know when I am free and clear of Covid if I cannot test? CDC guidelines don’t require a test at the end of isolation except for certain populations (e.g., health care workers). If you are free of symptoms, or the symptoms you have are mild and improving, there is no need to test to prove you are “free and clear.” However, you MUST wear a mask at all times when around others for days 6 through 10 after your positive test.


If you have been a close contact of a positive individual:

Who is a “close contact”? Anyone who was with a positive individual for a cumulative 15 minutes or more over the course of 48 hours prior to their symptoms or positive result.

  • Continue to work/attend classes as usual.
  • Wear a mask around others for 10 days.
  • Self-monitor for any symptoms, and test if any symptoms occur.
