ROLE OF REINFECTION IN TRANSMISSION DYNAMICS OF COVID-19: A SEMI-ANALYTICAL APPROACH USING DIFFERENTIAL TRANSFORM METHOD

| description | Reinfection of a recovered individual either as a result of relapse or new contact no doubt poses
a major threat to the eradication of an infection within the host community. In this work, the
role of re-infection in the transmission dynamics of COVID-19 was considered and analysed
using the semi-analytical tool Differential Transform Method (DTM). COVID-19 (also known
as Coronavirus) has shut down the economy of the world since it became a global pandemic.
A mathematical model was constructed with consideration of multiple pathways of infection
transmission, the treatment strategies and policies adopted (social distancing, wearing of face
mask and so on) to limit the spread of the infection globally. The non-linear system of equations
governing the model was solved using DTM and the resulting series solution was compared
with the standard numeric Runge-Kutta order 4 (RK4). It was discovered that re-integration of
a recovered individual into the susceptible community without observing the prevention
guidelines such as social distancing, washing of hands and proper sanitizing could increase
the spread of the infection since the recovered individuals are not guaranteed of immunity
against the infection after recovery. The study concluded that families of recovered patients
must ensure adequate preventive measure while integrating their recovered loved ones back to
their midst. |
