Environmental Influences on SARS-CoV-2: Temperature, Humidity, and Far-Infrared Radiation

Abstract

Countries under study here can be grouped into three Groups. Group A countries including, Hong Kong, Taiwan, Singapore, Malaysia, India, Bangladesh and Thailand and others to be classified experienced high Temperature, high Humidity and high Far Infrared Irradiation during the months of December 2019, January 2020, February 2020, March 2020 and April 2020, and have low IP 10000 (Infectivity) and low DP 10000 (Virulence) for SARS-COV-2. Group B countries, including Finland and Germany, and others to be classified experienced low Temperature, relatively high Humidity and relatively low Far Infrared Irradiation during those months, and have intermediate IP 10000 (Infectivity) and intermediate DP 10000 (Virulence) for SARS-COV-2. Group C countries, including Netherlands, United Kingdom, Belgium, France, Italy, Spain and Sweden and others to be classified experienced low Temperature, relatively low Humidity and low Far Infrared Irradiation, and are associated with very high IP 10000 (Infectivity) and very high DP 10000 (Virulence) for SARS-COV-2. There were reverse correlations between IP 10000 (Infectivity) and DP 10000 (Virulence), and Temperature, Humidity and Virulence. There was no correlation between Infectivity and Virulence. It is submitted that IP 10000 (Infectivity) and DP 10000 (Virulence) for SARS-COV-2 in different countries are determined in large part by environmental factors, including Temperature, Humidity and Far Infrared Irradiation, and that high Temperature, high Humidity and high Far Infrared Irradiation during the months of December 2019, January 2020, February 2020, March 2020 and April 2020 are associated with low IP 10000 (Infectivity) and low DP 10000 (Virulence) It is also submitted that elevated Temperature, high Humidity and high Far Infrared Irradiation will significantly lower the Viability, Infectivity and Virulence of SARS-COV-2.
