A perspective on India’s fight against COVID – 19

To understand the specific nature of the Covid-19 epidemic in India, this article looks at the disease through three elements of epidemiology – agent, host and environment. The agent is reported as two strains of SARS-CoV-2, in which one is more aggressive and spreads quickly. In terms of hosts, the article explores the variations in susceptibility within the Indian population, as well as the range of presentations in different hosts, from asymptomatic to severe. In terms of environment, the article analyses the question of weather may act as a protective factor against disease mortality in the country.
