I got a text response from the ID specialist I mentioned to you earlier...hopefully, I convey it effectively...any mistake is mine...
1) Criteria for Normalcy...this will basically depend on the num er of infected in a given community and the %positive tests. If the number gets so low that public health resources can trace everyone and have excellent quality testing, then most can go back to normal...however, no one has yet given a clear indication of what those criteria are going to be...but it will be awhile - like a long time...probably not until another year from now.
2) If someone is vaccinated they can still get it at least 10% of the time, if we can believe the Pfizer data. Therefore, it's not likely from a Public Heath standpoint that specific individuals will be able to go without a mask. (now that sucks for sure, so be prepared for substantial "blowback")...I'm probably missing something here, so keep asking the question, while being prep'd for a less-than-satisfactory response.
3) Due to HIPAA rules it is unlikely that businesses will be able demand personal health data.
Hope this helps...let me know your thoughts
