HCQ for COVID-19

1st treatment shown to reduce risk in March 2020, now with p < 0.00000000001 from 423 studies, used in 59 countries.

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

No treatment is 100% effective. Protocols combine treatments.

5,700+ studies for 141 treatments. c19hcq.org

Prospective study of HCQ prophylaxis in the USA, with 56 HCQ patients and 24 control patients, showing no significant differences. NCT04354870 (history)

Standard of Care (SOC) for COVID-19 in the study country, the USA, is very poor with very low average efficacy for approved treatments1. Only expensive, high-profit treatments were approved. Low-cost treatments were excluded, reducing the probability of treatment—especially early—due to access and cost barriers, and eliminating complementary and synergistic benefits seen with many low-cost treatments.
