Abstract

The number of coronavirus patients and the increasing inversion altitude follow a downward curve. Pollutants are dispersed throughout a greater thickness of the atmosphere as temperature inversion altitude rises, resulting in a decrease in their concentration at the earth's surface. Simultaneously, the quantity of patients with Coronavirus lessens. A decreasing and increasing relationship was found between the severity of pollutants and the number of coronavirus patients, despite a low significance level during each period. The correlation coefficient was negative for one day and nine to fourteen days. Therefore, the effects of the severity of pollutants and Covid-19 are not observed for periods of one, nine, or fourteen days. On the other hand, a positive correlation coefficient was found between 2 and 8 days. Therefore, there is a correlation between the virus infection and the onset of disease symptoms that ranges from two to eight days, with the three-day period showing the greatest correlation. It can be deduced from the relationship between the severity of pollutants, the number of patients, and the inversion altitude that occurs between 2 and 5 days that this virus is most prevalent in the Iranian metropolis of Tehran.
