Abstract
With the current struggles of the world nowadays with several epidemics, modeling the dynamics of diseaseoutbreaks has become much more important than any time before. In this context, the present paper aimsat studying a stochastic hepatitis B virus epidemic model with treatment cure rate. Our model consists ofthree epidemic compartments describing the interaction between the susceptible, the infected and the recovered individuals; an SIR model where the infected individuals transmit the infection to the susceptible ones with a transmission rate perturbed by white noise. Our paper begins by establishing that our hepatitis B stochastic model has unique global solution. It moves then to giving sufficient conditions for the stochastic extinction and persistence of the hepatitis B disease. Finally, our paper provides some numerical results to support the analytical study, showing numerically that the treatment cure rate facilitates the extinction of the hepatitis B disease among the population.
