Abstract

The aim of the paper is to mathematically analyze and describe the outbreak of COVID-19 (SARS-CoV-2) using compartmental models in epidemiology and understand the significance of ethical practices to break the chain of infection. A SEQIJR model of epidemic disease transmission which includes compartments each one for susceptible people (S), quarantine (Q) of exposed people (E), isolation (J) of infectious people (I), and a recovered population (R) is studied. The number of COVID-19 positive cases is rising at a significant rate across the globe. The coronavirus generally spread in two different ways. First, if a person inhale droplet from a person with COVID-19 positive who coughs out or exhales droplets or sneezes. Second, if a person comes in contact with the surface, which was contaminated by droplets or discharge from the nose, and then by touching his nose, mouth, and eyes. The spread of coronavirus can be stopped by interrupting the links of the chain of infection. But this interruption will also lead to multiple effects in terms of economic crisis as well. So, there is a great need to follow ethical practices while breaking the chain of infection.
