摘要

Cholera remains a persistent threat in low-resource settings, particularly in rural Sub-Saharan Africa where access to clean water, sanitation, and timely health information is limited. While conventional models focus on biomedical and environmental interventions, this study introduces a novel deterministic SIRB (Susceptible–Infected–Recovered–Bacteria) model that explicitly incorporates the impact of Rural Community Information Dissemination Centers (RCIDCs) as a behavioral intervention. The model captures both direct human-to-human transmission and indirect transmission via environmental contamination, with an awareness parameter modeling the influence of RCIDCs on hygiene practices and health-seeking behavior. Analytical results establish conditions for the stability of disease-free and endemic equilibria. Numerical simulations show that increasing RCIDC-driven awareness can reduce the basic reproduction number, \(R_0\) from 17.19 to below 0.13, transitioning the system to a Cholera-free equilibrium. Sensitivity analysis reveals that human contact is the dominant transmission pathway, and that RCIDCs significantly dampen outbreak intensity even in high-contact scenarios. These findings highlight the potential of community-based information networks as powerful, low-cost tools for cholera control, with implications for public health strategy in underserved regions.
