“…Based on different considerations, a significant number of mathematical models for COVID-19 transmission dynamics have become omnipresent. A series of mathematical models have been analyzed to delineate the transmission dynamic pattern of infectious diseases [3] , [39] , [40] , [41] . We considered the total population size among nine mutually exclusive compartments: susceptible individuals, S(t), are uninfected people with the disease but a chance to be infected; the first dose vaccinated individuals, V 1 (t), though still have to chance to be infected; second doses vaccinated individuals, V 2 (t), those who have completed the both dose vaccination within on time; exposed individuals, E(t), are those who are affected with a disease but have not yet developed respiratory illness; mild individuals, M(t), are indicated those who are asymptomatic; critical individuals, C(t), are express the COVID-19 symptoms clearly; non-hospitalized individuals, NH(t), are not in serious health crisis; hospitalized individuals, H(t), are those who are in critical health and respiratory crisis; and recovered individuals, R(t), are recovered against the disease who were infected.…”
