As per the World Health Organization (WHO), till May 16, 2020, about 4.4 million cases of Novel Corona virus (Covid-19) infections have been reported worldwide. As a part of corrective measures to prevent the spreading of this infectious virus, a statistical analysis of transferal behavior of Covid-19 is necessary. In this work, a comparative study of the spreading trends of Covid-19 in India and USA is presented. For investigating the trends of Covid-19 pandemic spread in India and USA, a statistical model based on Least Square Method (LSM) is proposed. The parameters affecting the spread pattern and steeper rise in Covid-19 graph is discussed in detail. From the trend line predictions, using LSM, it is observed that the spread pattern follows a second degree polynomial for India as well as USA. In addition, the numerical results revealed in the present work agree well with the actual spray pattern of the Covid-19 pandemic for both countries. The results also showed that the early stage spread rate of Covid-19 pandemic in India is very less as compared to USA due to the adoption of precautionary measures at the beginning of the pandemic spread.
