The prime focus of this study was to check the rate of mortality and extent of illness in relation to body mass index (BMI).Out of a total of 127 mortalities, 25.2% of deaths had normal weight ranges, whereas 33.9% of deaths were overweight and 40.9% were at obesity of different levels (p-value < 0.001), which shows the strong correlation between obesity and chances of mortality. Logically, in light of all the above mentioned facts, it can be concluded that the outcomes of this pandemic would have proven more dreadful and life threaten in societies where people have any of the above mentioned factors, specifically, increased BMI.
