RE-INFECTION CAN HAPPEN TO ANYONE: 26-year old world class cyclist Gaviria caught #COVID19 in Feb—hospitalized for 2 weeks. Prevailing wisdom suggested he’d at least be immune for foreseeable future.

It is finally happening. After the expected lag of 3-4 weeks, deaths from COVID in the US are finally coming down. This is fantastic, and I am confident that with
