So far many countries started using chloroquine to treat hospitalized only Covid-19 victims with very promising results. However, many doctors claimed that it should be used earlier (in case of even asymptomatic people having been exposed to infected peoples) in order to reduce the damages to organs because many peoples hospitalized are already in critical cases. India move in that direction.
AFAIK, this is prescription medication, so not much help while you wait for your turn. Online pharmacy price is hundreds of dollars, and could be counterfeit.
If prophylactic use of Chloroquine works than containment measures could be given up as severe cases needing hospitalization should disappear. However it will take time to find out if it works that well.
In the meantime, QUERCETIN (out of stock unfortunately) work as well as Chloroquine but you need 3 to 5 grams per day.
I suspect the Chelator GARLIC (raw) should work also as an IONOPHORE for ZINC.
