Conflicting and confusing guidance from the CDC, NIH, FDA, etc is not even remotely new. National guidelines/guidance and has always been designed to inform Doctors and healthcare professionals. It is for experts and professionals.
What is new in 2020+ is that we the people stopped listening to medical experts 1x1. This is dumb.
Why do we now choose to rely almost solely on guidance from politicians and administrative bureaucrats filtered through the insane lenses of the media? This will always be a bad idea.
Only professionals are truly qualified to judge the competency of the public health orgs and their guidelines.
Call your MD and ask real questions. Take charge of your own health. Ignore the talking heads.
