Abstract
An understanding of the origin, evolution and biochemistry (molecular biology) of SARS COV-2 is a prerequisite to its control. There is no definitive answer as to the origin of SARS-COV-2. The evolution of SARS-COV-2 can be gleaned from a comparative study of its Infectivity and Virulence in different populations and environments. A method for measuring the Infectivity and Virulence at the population level has been designed. IP 10000 defined as the Number of Individuals Infected with SARS-COV-2 Per 10000 Population and DP 10000 defined as the Number of Deaths Per 10000 Individuals Infected with SARS-COV-2 measure the Infectivity and Virulence of SARS-COV-2 respectively. There is no correlation between IP 10000 (Infectivity) and DP 10000 (Virulence). Based on their associated IP 10000 and DP 10000, one Group in Asia Pacific (Group A), two Groups in Europe (Group B and Group C), and one Group in North America (Group X) can be identified. Group A countries are also associated with high temperature, high humidity and high Far Infrared Irradiation. Group B countries are associated with low Temperature, low Far Infrared Irradiation but high Humidity whereas Group C countries are associated with low Temperature, low Humidity and low Far Infrared Irradiation. Group X countries are associated with low Temperature, relative low Humidity and relatively low Far Infrared Irradiation.
