Mathematical Modeling and Analysis of TB and COVID-19 Coinfection

Abstract: Tuberculosis (TB) and coronavirus (COVID-19) are both infectious diseases that globally continue affecting millions of people every year. They have similar symptoms such as cough, fever, and difficulty breathing but differ in incubation periods. This paper introduces a mathematical model for the transmission dynamics of TB and COVID-19 coinfection using a system of nonlinear ordinary differential equations. The well-posedness of the proposed coinfection model is then analytically studied by showing properties … Show more

“… We assume that people with COVID-19 are susceptible to infection with TB and vice versa based on several case reports on the co-infection of the two diseases [25] , [35] . Co-infected people cannot recover simultaneously from both infections; they can only recover from one disease at a time [41] , [42] . For instance, the recovery rate of co-infected latent TB and COVID-19 individuals is given as such that when the person recovers from tuberculosis, they move to the infected COVID-19 population at the rate .…”

“…For example, see [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] and the references therein. To better understand the dynamics of co-infection diseases, some studies have been developed (see [21] , [35] , [36] , [4] , [37] ). However, more work is still needed to understand the co-infection of the recently discovered pandemic disease COVID-19 with other diseases.…”
