New study shows impact of weather on the spread of COVID-19
A new study published in June 2021 by Yale University shows the impact of weather on the spread of COVID-19. The results show what time of year the virus thrives and which parts of the country are most at risk due to their climate.
The Yale School of Public Health studied the weather and COVID-19 cases from March 2020 to December 2020 in the United States. Their goal was to see the effect of weather factors in the spread of the coronavirus. This study broke new ground and corrects the previous results of other studies from the start of the pandemic.
The study focused on three main weather factors.
Heat, humidity and UV rays, which are mostly from the sun, have been shown to have noticeable impacts on the reproduction rate of the coronavirus. Overall, weather conditions accounted for 17.5% of the virus’s ability to multiply. Yale scientists say the weather is a big factor, but vaccines, masks and distancing contribute more to the speed at which the virus reproduces.
Humidity was the weather condition that had the greatest impact on the reproduction of the virus.
Here is the breakdown:
- Temperature: 3.73%
- UV radiation: 4.44%
- Humidity: 9.35%
This information has led scientists to conclude that the virus replicates faster in areas with cool, dry weather and low sunlight.
The researchers noted that areas such as New England are more at risk than southern areas when assessed based solely on weather conditions. This will be of concern to the people of these states after the wet, sunny and hot summer season ends.
