You wrote on these pages some months back about hydroxychloroquine being used by docs in Korea and Italy, and docs in the US starting to it off label on CV-19 patients. In your personal experience and opinion is it warranted for giving it to those with the virus, same question about prolactic use? I don't want to drag you into a potentially political question, but I believe you had mentioned that you were using it so I wonder what the view of that therapy is from one who probably was actually on the front lines in NYC ER in the past weeks and would have been seeing a lot of patients dying from CV-19.
