  The COVID-19 pandemic caused by the coronavirus had a significant effect on
social, economic, and health systems globally. The virus emerged in Wuhan,
China, and spread worldwide resulting in severe disease, death, and social
interference. Countries implemented lockdowns in various regions to limit the
spread of the virus. Some of them were successful and some failed. Here,
several factors played a vital role in their success. But mostly these factors
and their correlations remained unidentified. In this paper, we unlocked those
factors that contributed to the success of lockdown during the COVID-19
pandemic and explored the correlations among them. Moreover, this paper
proposes several strategies to control any pandemic situation in the future.
Here, it explores the relationships among variables, such as population
density, number of infected, death, recovered patients, and the success or
failure of the lockdown in different regions of the world. The findings suggest
a strong correlation among these factors and indicate that the spread of
similar kinds of viruses can be reduced in the future by implementing several
safety measures.
