The CDC and DPH guidance for respiratory virus:
Massachusetts Department of Health Information
When you have ANY respiratory virus (FLU, COVID-19, RSV) - stay home and away from others if you have respiratory virus symptoms. These symptoms can include fever, chills, fatigue, cough, runny nose, and headache, among others.
Return to normal activities when, for at least 24 hours, both are true:
- Your symptoms are getting better overall, and
- You have not had a fever (and are not using fever-reducing medication)
When you go back to your normal activities, take added precaution over
the next 5 days, such as taking additional steps for cleaner air, hygiene, masks, physical distancing, and/or testing when you will be around other people indoors.
Keep in mind that you may still be able to spread the virus that made you
sick, even if you are feeling better. You are likely to be less contagious at
this time, depending on factors like how long you were sick or how sick you
were.
