Risk Factors of SARS-CoV-2 Infections: A Global Epidemiological Study
ABSTRACT
Since the first governmental recognitions of the pandemic characteristic of the SARS-Cov-2 infections, public health agencies have warned about the dangers of the virus to persons with a variety of underlying physical conditions, many of which are more commonly found in persons older than 50 years old. To investigate the statistical, rather than physiological basis of such warnings, this study examines correlations on a nation-by-nation basis between the statistical data concerning covid-19 fatalities among the populations of the ninety-nine countries with the greatest number of SARS-Cov-2 infections plus the statistics of potential co-morbidities that may influence the severity of the infections. It examines reasons that may underlie of the degree to which advanced age increases the risk of mortality of an infection and contrasts the risk factors of SARS-Cov-2 infections with those of influenzas and their associated pneumonias.
