Existence and uniqueness of solutions, stability of the model and basic reproduction number were derived. In this article, the vulnerability of COVID-19 in Tirupathur district, Tamilnadu, India is discussed to exhibit the flow of variables of the model using numerical simulations. Also, analysis of recovered is explored for Siddha and allopathy treatments.</p>}, number={2}, journal={Journal of Informatics and Mathematical Sciences}, author={Lakshmi, V.S.V.
