In the dengue-prone neighborhoods of Selangor, Malaysia, a quiet paradox persists: residents understand the disease, yet the behaviors that would stop it remain inconsistent and fragile. A study from Hulu Langat district reveals that knowledge, long treated as the engine of public health, is not sufficient to move people to act — that between knowing and doing lies a terrain shaped by fear, social trust, and the felt sense of whether one's efforts will matter at all. The findings ask us to reconsider a foundational assumption of modern health communication: that information, delivered clearly

Public health authority credibility and community trust become critical assets; WHO and regional health organizations gain influence in shaping behavioral intervention strategies; local governments must balance top-down IVM programs with bottom-up community engagement.
Similar to 1960s-70s malaria eradication campaigns that failed due to underestimating social factors; current dengue control mirrors early HIV/AIDS prevention challenges where knowledge alone proved insufficient.

Malaysian study reveals dengue prevention requires behavioral change beyond knowledge, indicating public health campaigns need emotional/social strategies to improve compliance with preventive practices.

Households face continued dengue risk despite awareness efforts; increased healthcare costs, productivity losses from illness, and need for private vector control services. Consumers may demand more effective behavioral interventions and integrated pest management solutions.
Governments should shift public health strategy from knowledge-only campaigns to integrated approaches addressing emotional and social barriers. This may increase spending on community engagement programs, behavioral psychology research, and localized interventions. Potential for new regulatory frameworks requiring emotional/social impact assessments in disease prevention policies.
