Chloroquine is effective in preventing the spread of SARS CoV in cell culture. Favorable inhibition of virus spread was observed when the cells were either treated with chloroquine prior to or after SARS CoV infection
So why the hysterical overreaction to the use of HCQ (Hydroxychloroquine) , in direct opposition to the CDC’s own research?
A suspicious and pessimistic interpretation might suggest that the Wuhan Flu pandemic was a ginned up excuse to damage President Trump’s prospects for reelection, and that the government apparatus dedicated to prevention and control of disease was repurposed years ago as a weapon in the Deep State’s arsenal. So a cheap, relatively safe and possibly effective treatment (and maybe prophylaxis*) was an unacceptable complication in the war against the President, and if thousands of Americans died because of the attacks on HCQ, well… to our enemies that’s acceptable.
*measures designed to preserve health (as of an individual or of society) and prevent the spread of disease.
