I have an acquaintance that looked to be going beyond the brink with Covid-19, barely able to breathe, whose symptoms promptly reversed when the doctor prescribed some sort of “drug cocktail”. Not sure what that cocktail was, but I suspect it might have been the one being touted lately. Anecdotal evidence, I know.
My daughter’s HS classmate and a onetime neighbor is an ER doc in Brooklyn. She came down with a cough. Self Q’ed in her apartment for four days before calling her boss and asking for help as she had a fever and was very short of breath. Her boss arrived, took her in his car while he wore PPE to the hospital. They gave her high volume O2 which helped. They ICUed her and immediately gave her HCQ and ZPack which continued for five days. On day 6 she was released to return home. This was ten days ago. So two weeks ago a Brooklyn hospital used HCQ as a first treatment in ICU.
