HCQ for COVID-19
1st treatment shown to reduce risk in
March 2020, now with p < 0.0000000001 from 426 studies, used in 59 countries.
No treatment is 100% effective.
Protocols combine treatments.
Prospective study of 1,331 healthcare workers in India showing SARS-CoV-2 reinfection incidence of 9.7 per 1,000 individuals (2.97 per 100,000 person-days) during the Omicron-dominant period. 52 participants used HCQ or ivermectin prophylaxis however authors do not report results for treated/untreated patients.
Study covers ivermectin and HCQ.
