Abstract

COVID-19 a pandemic due to novel corona virus emerged from Wuhan, China in December 2019 and now the whole world facing its threat. This is a disaster pandemic for  almost every nation on the earth. Such novel corona virus impacts on every country in  the world irrespective of race, ethnicity, environment and economic status. In this study, an attempt has been made to use statistical process control technique to understand spread of COVID-19 in some major states of India as well as India. Warning limits and control limits has been estimated and discussed for average weekly growth index of COVID-19 pandemic. Study indicates that there is no hope for controlling the  pandemic in near future because the average weekly growth index of COVID-19 pandemic is far from zero.
