A NARRATIVE REVIEW -HERD IMMUNITY A HIDDEN SOLUTION OF COVID-19

Author(s): Sanidhya Sethia*, Aparna Singh

Abstract

The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) that causes Coronavirus disease 2019 (COVID-19) is currently the largest infectious disease pandemic of the 21st century. Its remarkable effects on politics, public health, medicine and research have raised many issues and revived several fundamental ideas in the ??e?d? of infectious diseases and immunology. Previous researchers have made an effort to forecast the total number of Coronavirus disease 2019 (COVID-19) cases in China. Since then, though, the virus has quickly changed into a global pandemic that affects numerous nations worldwide. Serious discussions have taken place regarding how to respond to the spread of this disease, especially by European nations. Possible responses have ranged from closing institute, universities and schools to lockdowns in major cities and nations. Another option would be to let the COVID-19 virus (SARS-CoV-2) propagate so that i will boost population herd immunity while simultaneously protecting the most vulnerable populations, which include the elderly and people with many comorbidities. Herd immunity is an important concept in epidemic regulation. It states that only a fraction of a population needs to be immune to an infectious agent (via vaccination or natural infection) for it to stop transmission of virus and decrease their ability to cause large incidences of disease. An important question to answer in the existing COVID-19 pandemic is when, how and at what cost community immunity or herd immunity can be achieved. Here, we go through the fundamental ideas of herd immunity and talk about how they apply to COVID-19.
