Lockdown Phases and Changing Clusters of Indian States with Respect to Number of Cases of COVID-19

ABSTRACT

The novel coronavirus (COVID-19) incidence in India is currently experiencing exponential rise with apparent spatial variation in growth rate and doubling time. We classify the states into five clusters with low- to high-risk category and identify how the different states moved from one cluster to the other since the onset of the first case on January 30th, 2020, till the end of November 30th, 2020. Result clearly shows the impact of the lockdown and the unlock phases in the changing formation of the clusters. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
