when you are exposed, i do think you can end quarantine early. i do agree the cdc did the right thing on that policy, you are vaccinated and you don't have to haul away in your house and waiting to test. if you tested positive or your symptomatic and you just wait. we have seen patients who have been testing positive, not just day ten, they have been testing positive for 12 days. that's not the norms. it's possible. we know there are people who are still infectious. without testing and without a distinction for vaccinated individuals and without some criteria to say what does it mean that your symptoms are resolving or what are your symptoms you should be looking for. these all mimics of common cold. true cold has no ability to get a test or not tested and for them to be locked in this confusing advisory from the cdc for weeks even.
