An SVEIAR mumps infection model with vaccination and latent infection
According to the known mechanism of mumps transmission, a SVEIAR mumps infectious disease model with vaccination and incubation period was established by using the qualitative and stability theory of ordinary differential equation, and the basic regeneration number of the model was obtained. The existence of the equilibrium points is given and it is found that the disease-free equilibrium point is globally asymptotically stable when
. The case data of mumps patients in Jiangsu Province is collected to simulate the epidemic trend of mumps in the next few years. Finally, the sensitivity analysis of parameters shows that the incidence of mumps will continue to increase in recent years. Improving public awareness preventing mumps, developing effective vaccination strategies and strengthening physical exercise can improve the body quality and immune function, so as to prevent the occurrence of mumps, and then control the spread of mumps.
