Rapid fall in Active cases of COVID-19 in Indian Territory of Lakshadweep Further Confirmed the Existence of A Long Term Non-Specific Immunity in the Population that protected against Severe COVID-19 with decreased Mortality

Abstract

The SARS-CoV-2 virus, the causative agent of COVID-19, has become a formidable enemy to mankind for its ability to quickly mutate & evade the immune system of the host. We have reported earlier that the territory of Lakshadweep in India reported the first case of COVID-19 in January, 2021 long after its invasion in the other states of the country. And following its first appearance, there was gradual spread of the disease in the population which was waning by the end of March, 2021. The waning of COVID-19 was attributed to prior immunization of the population with MMR (Mumps Measles Rubella) vaccine. In this article we have continued the study until July 31, 2021 and a significant observation was that after a pause in the number of COVID-19 cases, there was an increase in number of confirmed & active cases of COVID-19. However, an abrupt fall in the number of active cases of COVID-19 followed and by six months there were insignificant number of active cases of COVID-19. Significance of these observations has been discussed in this article.
