As I mentioned to Curly in an earlier post, we have two MDs in our extended family with one being an ID specialist on the faculty of a med school and the other being a Critical Care/Pulmonary (ICU) Doc...the following are my interpretations, not their words (caveat delivered)...
>As regards masks...the kind they use (N95) are very carefully 'fitted' in order deliver a high level of protection...this is very unlikely to be the case w/in the general public...not to say they shouldn't be used if available. The operative word for mask use should be "mitigation" rather than "prevention", so surgical masks - or cloth masks, if other options aren't available - should be employed to reduce the viral load expelled by the wearers. 'Viral Load' is not fully understood, but enough so to warrant the use of masks.
>w/r/t the "Hydroxy" question...that topic has been well discussed and to the best of my knowledge it is not part of the recommended protocol in ICUs...don't believe President Trump received it at Walter Reed either.
>Regarding the Barrington Declaration, I've included a link with responses to it. Beyond that, my earlier response to Curly addressed that issue (Herd Immunity)...you can do a quick search of my posts (I'm a newbie, so not too onerous). Given the sharply rising COVID case loads in nearly all states, this gives my MD friends the most anxiety (i.e total overload of the HC system).
>Finally, as regards requiring proof of immunization, HIPAA rules would get in the way.
Hope this helps...and again, thanks for going 'above and beyond' with the vaccine trial.
