First thing I noticed was that he was a Dr of Osteopathy which down here means he took the medical exam but is not a medical doctor by education...
With regard to the death certificate, it has been suggested down here that coronavirus is the cause of death if they tested for it no matter what the underlying causes may have been. The next county to me is Tom Green with a population of 118,000. So far they have tested positive for 41 cases and have had one death-a man up in his 70's. It was mentioned that he had underlying causes in the paper. One of my nurse friends from the hospital said he was on chemo.
What looks strange is that up in NY, they were told to put Covid-19 on any death certificate whether tested or not if there was not a clear cause of death. NY just added 3700 deaths as a result which had been neither reported or tested.
For the most part of the country, the infection rate is way less than 1% at this point. I am guessing that it is actually much higher than that but that most just shake it off, or never have shown symptoms.
It is clear that it is a political action to try to get rid of Trump when all else has failed. Hard to know how severe the average infection actually is.
