That's the guy whose hospital has lost a several patients.
Midland Co has had 927 cases and 17 deaths. Odessa, 2 hospitals have had 1392 cases and 11 deaths.
I'd say that's medically significant. The death count would be even lower for Odessa if BOTH hospitals would have treated early and initially with Hydroxychloroquine. Only one hospital here did.
He speaks from experience in treating the very serious cases of Covid-19. With that said, I see no issues with putting Dr. Bartlett's hypothesis to the scrutiny of scientific testing. If he is right it's a game changer, if he's wrong then we need to keep looking.
