The present study is a comparison between the reported number of cases in two districts i.e. Sheohar and Begusarai of Bihar state in India. While Sheohar had the minimum number of reported cases the other, Begusarai reported maximum number of cases during a peak of the pandemic (15th to 17th April 2020) simultaneously. The present paper aims to examine the changes in NO2 in the atmosphere over these districts during the above mentioned dates. The Covid19 data was available through the ISRO portal “Bhuvan” and the national portal of India for Covid-19, i.e. covid 19 india.org. In addition, the data form the COVID-19 test centers of Begusarai was also collected and was used for Hypothesis testing with Chi Square. QGIS 3.12.3 software has been used for processing satellite data for atmospheric NO2 and map generation [1]. MS excel has been used for calculation of Chi-square values. The observation from the data shows that the atmospheric concentration of NO2 was indeed lower in the Sheohar district. The Chisquare results for the collected data indicated that the Covid-19 was equally probable over all age groups, and ethnical groups and gender.
