In this paper, the stochastic vector-host model has been proposed and analysed using nice properties of piecewise deterministic Markov processes (PDMPs). A threshold for the stochastic model is derived whose sign determines whether the disease will eventually disappear or persist. We show mathematically the existence of scenarios where switching plays a significant role in surprisingly reversing the long-term properties of deterministic systems.

Sample paths of $I_H(t)$ (Example 4.1). In the deterministic systems (LEFT) there is persistence in state 1 and extinction in state 2. In the switched system (RIGHT), the infection persists
Sample paths of $I_H(t)$ (Example 4.2). In both deterministic systems (LEFT), $I_H(t)$ converges exponentially fast to 0. Switching makes the disease persist (RIGHT)
