If you had COVID, you shouldn’t have to quarantine.

It appears that if you’ve had COVID within 3 months and have recovered, you don’t actually have to quarantine if you’ve been exposed, according to the CDC.

May be an image of text that says 'and who meets the following criteria does NOT need to stay home. Someone who has been fully vaccinated and shows no symptoms of COVID-19. However, fully vaccinated people should get tested 3-5 days after their exposure, even if they don't have symptoms and wear a mask indoors in public for 14 days following exposure or until their test result is negative. Or Someone who has COVID-19 illness within the previous 3 months and Has recovered and Remains without COVID-19 symptoms (for example, cough, shortness of breath)'

And “People who had COVID-19, recovered, and completed 10 days of isolation and then during the 90 days following the end of isolation come into close contact with someone with COVID-19 do not have to quarantine or get tested if they do not have symptoms.”

Of course, the CDC is always changing their rules, but they shouldn’t in this case. Natural immunity is durable and long-lasting and possibly more effective than one or two vaccines.
