Stochastic dynamics of Chikungunya virus infection model incorporating general incidence rate and immune responses.

9 , we can clearly observe that as the noise intensity σ increases, the amplitudes of CHIKV particles, B-cells, and CTLs all exhibit an increasing trend.

The MFPT exhibits a decreasing trend with both decreasing the reversion rate and increasing the noise intensity. 8 Conclusion In this study, we propose a kind of CHIKV infection model incorporating dual immune responses in both deterministic and stochastic frameworks, where the stochastic perturbation is introduced into the general incidence rate by the log-normal OU process.
