This is totally incorrect. First, the MOA of hydroxychloroquinoline (HCQ) in malaria is completely incorrect. It works through lysosomal function regarding the presentation of antigens to the immune system. Secondly, Covid-19 is not a DNA virus but an RNA virus, DNA is not involved nor is an interaction with hemoglobin involved in the anti-malaria activity of HCQ. There is nothing in the scientific/medical lit as of today about any interaction with hemoglobin and covid-19, nor any reason to think HCQ would interfere in such process.
