From Virology Journal 2005: Chloroquine is a potent inhibitor of SARS coronavirus infection and spread




Severe acute respiratory syndrome (SARS) is caused by a newly discovered coronavirus (SARS-CoV). No effective prophylactic or post-exposure therapy is currently available.


We report, however, that chloroquine has strong antiviral effects on SARS-CoV infection of primate cells. These inhibitory effects are observed when the cells are treated with the drug either before or after exposure to the virus, suggesting both prophylactic and therapeutic advantage. In addition to the well-known functions of chloroquine such as elevations of endosomal pH, the drug appears to interfere with terminal glycosylation of the cellular receptor, angiotensin-converting enzyme 2. This may negatively influence the virus-receptor binding and abrogate the infection, with further ramifications by the elevation of vesicular pH, resulting in the inhibition of infection and spread of SARS CoV at clinically admissible concentrations.


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. In addition, the indirect immunofluorescence assay described herein represents a simple and rapid method for screening SARS-CoV antiviral compounds.



All I can say is that we have been lied to by the CDC (Dr. Redfield), NIAID and governments at all levels concerning the pandemic. The above article from 2005 is from a well respected journal which gives us a clear pathway to address COVID-19. If everyone would have been given a 30-60 supply of chlorquine in conjunction with zinc, we would have built up herd immunity, saved the economy and not be on the verge of civil war.

We now need to ask why we can’t do this same measure today.
