I don't know (and doubt) this has been said already by anyone else, but...
Re: Hydroxychloroquine. I read something that said that the virus affects how oxygen is absorbed by the blood. If you take pneumonia for example, it typically affects one lung and not both simultaneously as this virus appears to do. Whatever way the Hydroxy works on Malaria is similar to how it helps with COVID-19.
There was also a video I watched that explained how certain protein sequences in the Corona Virus DNA structure couldn't have come about naturally, which strongly suggests it was created in a lab.
