CDC has known since 2005 that (hydroxy)chloroquine kills the SARS virus. (SARS-COV-2 = Covid-19)
There is no money in it as it is a safe generic drug available since 1950 which costs 10c a dose.
A cure with it takes 6 days on average so less than $1
NIH knew too.
Both CDC and NIH published the same findings on the same day… almost 15 years ago.
