In fact, the COVID-19 epidemic model is unavoidably subjected to the environmental noise, which made the parameters involved in the system often fluctuate randomly around some average values as the surrounding environment fluctuation. In this paper, we propose a stochastic COVID-19 model adopting a generalized incidence function [25, 26] as follows: Note that the COVID-19 epidemic models may be perturbed by telegraph noise which can causes the system to switch from one environmental regime to another [22] . To study the dynamical behaviour of an epidemic model, we firstly need to consider whether the solution is global and positive. This paper investigates a stochastic epidemic model describing COVID-19 dynamics affected 125 by mixture of environmental perturbations modeled by white and telegraph noises.	./cache/cord-349841-eigcqb1b.txt	./txt/cord-349841-eigcqb1b.txt
