Many of the COVID-19 infections are in tourists (who have not gotten lots of UVB), not locals
"....Cusco, 6.7 % of men are obese, compared to Lima, where 24.4 % are.""
Note - The highest altitude state in the US (with the most UVB) also has the lowest obesity
Hypothesis: Colorado has the best UV (and thus best health) in the US has the following chart
Vitamin D Life Items in both categories UV and Virus:
- More UVB, less Coronavirus – including SARS-CoV-2 – Aug 2020
- Less COVID-19 at high altitude due to more Vitamin D or other possible reasons – July 2020
- Far fewer COVID-19 deaths in the summer (Europe, Canada)
- High-altitude Cusco, Peru has far lower rate of COVID-19 than others (high UVB and Vitamin D) - June 2020
- Influenza Virus aerosols killed by 10 minutes of sunlight (far faster if use UV-C) – Nov 2019
- Influenza Virus aerosols killed by 10 minutes of sunlight (faster if use UVB, UVCC– Nov 2019
- Ultraviolet light kills cold and flu viruses, and generates Vitamin D in the skin
