Impulsive Vaccination SEIR Model with Nonlinear Incidence Rate and Time Delay
This paper aims to discuss the delay epidemic model with vertical transmission, constant input, and nonlinear incidence. Some sufficient conditions are given to guarantee the existence and global attractiveness of the infection-free periodic solution and the uniform persistence of the addressed mode...
