UV radiation from the sun increases ‘by a factor of 10’ by summer and could be key in slowing COVID-19

Efforts to combat the growth of SARS-CoV-2, which is the virus that causes COVID-19, are ubiquitous: quarantines, social distancing and the countless activities that have been suspended or canceled to help limit COVID-19’s spread throughout the world.

Now increased sunshine could help in the Northern Hemisphere. Data compiled by AccuWeather of the ultraviolet energy received from the sun from Jan. 1, 2019, to the present is a reminder that substantial increases of UV rays have begun and will continue for the next several months.

Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter (greater than 1 million Kelvin, or 1,799,540 F). (NASA/Goddard/SDO AIA Team)

 

AccuWeather examined the daily UV Index from seven major cities worldwide from Jan. 1, 2019, through mid-March 2020 compared to the 10-year average of the daily UV Index for those cities. (The 10-year averages accounted for ozone and other gases in the atmospheric column.)

If the coronavirus behaves like most other viruses, then as the sun grows stronger day by day as we head towards the summer solstice, the stronger sun and increased hours of sunshine may start to take their toll on the virus, thereby helping to slow its spread, particularly as the sun gets stronger in April and May,” said AccuWeather Founder and CEO Dr. Joel N. Myers. “The point of most rapid increase in sun intensity, as well as duration of the day, is right now,” he added, referring to the days around the vernal equinox, which occurs March 19.
