Epidemiology

Introduction

• Sebastian Rushworth, (November 2021) :

In early 2021, the Delta variant springs in to existence in India, and rapidly races through the population. Population antibody testing reveals that roughly 50% of India’s population become infected over the course of just a few months, with the proportion of the population with antibodies rapidly rising from 20% to 70%, at which point sufficient population immunity sets in for viral spread to drop down to low endemic levels.
