problems ()–() are studied in Choudhary et al [
14] and the existence of classical and weak solutions are proved for bounded and unbounded kernels, respectively. We investigated the mild and classical solutions, see Kumar et al [
15], of a partial integro‐differential equation () together with chaperone under assumption () and
, respectively. In earlier studies [
1, 6], the stability of equilibria for disease‐free and disease state are examined by converting the equations into a system of ODEs.…”
