Bayer donates 3M chloroquine phosphate tablets for potential Covid-19 treatment
An alternate zinc ionophore with less side effects is Quercetin [1] [2] which some people here already take for other reasons, myself included.  It is most beneficial if being taken prior to infection to slow the RNA transcoding process by getting more zinc into the cells, assuming one is not deficient in zinc to begin with.  I mention this because by the time someone is talking to a doctor, the virus has likely already replicated in vast amounts.  Chloroquine currently requires a prescription, at least in the U.S.  I am neither a doctor or a scientist, as per my profile.  Very few doctors study molecular biology as a hobby or as part of their career.[Edit] To be clear, I am not a doctor and this is not medical advise.  Please research this topic yourself.  There are many studies on nih.gov on zinc ioniphores.  Here is a video discussing both compounds by a doctor. [3]  They are also not giving medical advise.[1] - https://examine.com/supplements/quercetin/[2] - https://www.ncbi.nlm.nih.gov/pubmed/25050823[3] - https://www.youtube.com/watch?v=vE4_LsftNKM
