Background: With 416,686 confirmed cases and 18,589 deaths over three months, COVID 19 is one of most menacing pandemic of recent times. The causative agent, SARS–CoV–2 causes moderate to severe lower respiratory tract infection depending on the age, comorbidity and geographical location. Purpose: This study was done to compare and analyze the effect of average daily temperatures on the severity of the disease in terms of daily new deaths in worst hit regions. The study was also aimed to find out if there was any preferred temperature for epidemic to escalate. Method: The severity of disease was assessed in terms of daily new deaths which was charted against variation of average temperature of same day. Result: It was recorded that there was sharp descent in average daily temperature almost every time before rise and during peak of the deaths. It was also found that elevation in temperature curve was followed by decrease in daily deaths, suggestive of decrease virulence of virus at higher temperatures. Conclusion: Based on data evaluation, there was variation in daily deaths counts with change in average daily temperature which is suggestive of higher virulence of SARS CoV –2 at lower temperatures and vice versa.
