Tailoring dengue health communication: Survey-based strategies to reduce message fatigue across risk areas

Message fatigue is associated with regional dengue risk, demographic factors, and perceived risk. A uniform health communication approach may not be effective across different populations. In high-risk regions, message fatigue is more pronounced. Repetitive warnings may contribute to disengagement, suggesting a need for communication strategies that reduce redundancy and emphasize localized, actionable information. In low-risk areas, messages should focus on engagement, particularly for men, who exhibited higher fatigue in this study. Simplified messaging can reduce cognitive overload for lower-educated populations. Addressing message fatigue can enhance the effectiveness of dengue prevention campaigns and sustain public engagement in long-term health communication efforts.
