Viral infection is a race between the reproduction rate of the virus, versus the bodys ramping up of antibody production. If you can disrupt the viruss reproduction rate in the early stage (through hydroxychloroquine plus zinc plus azithromycin), then you give the immune system extra time to ramp up.
Bingo!

I am guessing there are a whole lot of front line docs taking plaquenil according to the royal college of India protocol.
