32nd treatment shown to reduce risk in December 2021
 
*, now known with p = 0.000052 from 5 studies.
Lower risk for mortality, hospitalization, recovery, and cases.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Higher Solar Irradiance Is Associated With a Lower Incidence of Coronavirus Disease 2019
Mar Guasp, Carlos Laredo, Xabier Urra
Clinical Infectious Diseases, doi:10.1093/cid/ciaa575
We studied the relationship between the incidence of coronavirus disease 2019 (COVID-19), demographical, and climatological measurements in different regions across the world. Lower solar irradiance and higher population density were independent predictors of greater COVID-19 outbreaks. Further studies on the potential protective effect of sunlight over COVID-19 are warranted.
