While the authors are clearly aware of the differences between UVB (which produces Vitamin D) and UV (UVA+ UVB) they only use UV data.
UVB has much stronger variations in intensity with season than UV.
If they were to have used UVB (Vitamin D) data, we suspect that the assocation with COVID-19 would be even stronger
Items in both categories Virus and UV are listed here:
- COVID and other Virus fought by UV - many studies
- Model discovered: More UV, less COVID (many excellent charts) – Sept 2022
- COVID hospital deaths reduced 2X by 8 days of UVB – pilot RCT May 2022
- UV and COVID: Prevention and perhaps treatment
- 11 percent fewer COVID-19 deaths if lockdowns had allowed sunshine – Nov 2021
- COVID-19 deaths - 30 percent fewer if high UVA (US, etc) – Aug 2021
- 4th highest county in the US has a very low COVID-19 rate (high UV, high vitamin D)
- COVID-19 onset strongly associated with latitude in Europe (Vitamin D)– Jan 21, 2021
- UV provides the best explanation of COVID-19 variation in Italy (74 pcnt) – Nov 2020
- 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
UV and D starts with
- Overview UV and vitamin D
- Vitamin D bulb for use in the home - or perhaps office,
- Sun and UV
- Sun and Vitamin D category has
320 items - UV and Vitamin D calculators, Vitamin D from low-cost UVB lamps
- UVB added in classroom reduced cavities, increased height, increased academics. etc
- Vitamin D from the sun without the heat (silver-coated plexiglass)
- COVID and other Virus fought by UV - many studies 16+
- 3.3 X more likely to be Vitamin D deficient if wear long-sleeves – Oct 2022
- Non-oral Vitamin D should be a better form for MS, food allergy, PTSD, etc. – many studies UV, etc.
Much more variation in UVB than UVA with season Brazil 2009
Vitamin D varies with latitude has the following UV chart for Chile

NHR = Nursing Home ResidentsCOVID-19 deaths vs UV
A significantly stronger impact in mortality and morbidity by COVID-19 has been observed in the northern Italian regions compared to the southern ones. The reasons of this geographical pattern might involve several concurrent factors. The main objective of this work is to investigate whether any correlations exist between the spatial distribution of COVID-19 cases and deaths in the different Italian regions and the amount of solar ultraviolet (UV) radiation at the Earth's surface. To this purpose, in this environmental ecological study a mixed-effect exponential regression was built to explain the incidence of COVID-19 based on the environmental conditions, and demographic and pathophysiologic factors. Observations and estimates of the cumulative solar UV exposure have been included to quantify the amount of radiation available e.g., for pre-vitamin D3 synthesis or SARS-CoV-2 inactivation by sunlight. The analysis shows a significant correlation (p-value <5 × 10-2) between the response variables (death percentage, incidence of infections and positive tests) and biologically effective solar UV radiation, residents in nursing homes per inhabitant (NHR), air temperature, death percentage due to the most frequent comorbidities. Among all factors, the amount of solar UV radiation is the variable contributing the most to the observed correlation, explaining up to 83.2% of the variance of the COVID-19 affected cases per population. While the statistical outcomes of the study do not directly entail a specific cause-effect relationship, our results are consistent with the hypothesis that solar UV radiation impacted on the development of the infection and on its complications, e.g. through the effect of vitamin D on the immune system or virus inactivation by sunlight. The analytical framework used in this study, based on commonly available data, can be easily replicated in other countries and geographical domains to identify possible correlations between exposure to solar UV radiation and the spread of the pandemic.
