报告摘要:We propose a spatial model for vector-borne diseases incorporating cognition-driven host mobility via Fokker–Planck type diffusion. Susceptible hosts disperse more in high-risk areas, while infected hosts reduce movement near high-recovery regions. The basic reproduction number \(\Re_0\) is derived and serves as a sharp threshold: the disease-free equilibrium is globally stable if \(\Re_0 \leq 1\), whereas the system persists if \(\Re_0 > 1\). We analytically establish how \(\Re_0\) depends on cognitive parameters: it increases with infected cognition \(c_I\) if \(\Re_0 > \bar{r}\), and decreases with susceptible cognition \(c_S\) under suitable spatial heterogeneity conditions. Numerical simulations for dengue transmission confirm these theoretical insights, demonstrating how cognitive movement shapes outbreak patterns and informing targeted control strategies.
