If you have recently tested positive for Covid, you need to isolate based on your state guidelines. It is recommended that if you test positive, you should isolate for 5 days after your positive test. If you live in a home with other people and they test positive after you, your 5 days start all over again. It is recommended that you do not go into any public institution like a grocery store, gas station, restaurant, etc. It is also recommended to notify any person you have been in contact with that you have tested positive. You are considered contagious 2 days (or 48 hours) before symptoms start, so any contact you have had within the 2-day period before you had symptoms.
