Not all medical professionals have the same credentials. Your local doctor had about 3-4 months of courses in epidemiology and virology during their first two years in medical school and since then has focused on treating patients, which rarely involves those subjects even if they practice in specialties that treat those issues.
That might not seem true but here’s the truth, when you are treating a patient it doesn’t matter how they got the disease, they have it and now you need to “fix it” other then making sure you are wearing the proper PPE (so you don’t get it) and warning family members to be evaluated if they get similar symptoms.
Then you have people (some of whom are PhDs) who devote their entire life to studying Public health, epidemiology and virology, those are the experts you need to listen to, your community health care provider knows only enough to be dangerous, to use a military analogy, community doctors are 2nd lieutenants, the experts are generals. The Lieutenants May have a good idea of what’s happening on the front line but are too deep in the nitty gritty to give you a proper opinion on the overarching strategy and if it’s working.
Signed a person on the front lines who knows his opinion on this whole affair isn’t informed enough and thus defers to those experts.
