Temperature, humidity, and other environmental factors can influence the spread of diseases. To investigate the impact of environmental perturbations and state changes on pertussis, this study established a random pertussis model with immunity and Markov switching. This stochastic model presented a global positive solution. Subsequently, using Itô’s lemma and Lyapunov function, we concluded that the disease will become extinct. Then, a critical value Re0 was introduced. It was established that the stochastic model with Markov switching has an ergodic stationary distribution when Re0 > 1, which implies that this infectious disease will persist and remain prevalent. Some examples are presented to further substantiate our theoretical conclusions.
