Abstract

We assumed a homogeneously mixed population and that the disease does not only spread by direct contact with an infected individual but also by touching infected surfaces (environment). We then propose an SQEIRVS model and validate correlation between upsurge in transmission and touching surfaces contaminated by droplets from COVID-19 infected individual. We performed the appropriate analyses for positivity and boundedness, reproduction number, and stability. The problem was modelled numerically. Furthermore, we identified the criteria required for the stability of both DFE and endemic equilibrium. Asymptotically, the DFE is stable. Additionally, the endemic equilibrium is stable. The numerical results showed that treatment and immunization are effective in reducing the spread of the infections.
