HCQ for COVID-19

1st treatment shown to reduce risk in March 2020

^*, now known with p < 0.00000000001 from 422 studies, recognized in 42 countries.

Lower risk for mortality, hospitalization, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine complementary and synergistic treatments. ^* >10% efficacy in meta analysis with ≥3 clinical studies.

4,100+ studies for 60+ treatments. c19hcq.org

Retrospective 863 COVID-19 patients in Burkina Faso, showing lower mortality, lower progression for outpatients, and faster viral clearance with HCQ/CQ treatment. Only the lower mortality was statistically significant. NCT04445441 (history).
