So many people are getting it, including a lot for the first time who are super careful and wear masks (that i know irl and online). I presumably have it, all the symptoms but haven't tested positive despite being on day 6

The nasal sprays are a great idea, thanks for that! Out of curiosity, how often do you use them? Once daily?
They say every four to six hours. I use them before and after any potential exposure, or in the morning, at lunch and after work.
