ILOILO CITY — Dengue cases in Iloilo province have plummeted 65 percent this year, falling from 1,714 infections and nine deaths in the January‑to‑mid‑May period of 2025 to just 604 cases and two deaths in the same window of 2026. Provincial Health Officer Dr. Maria Socorro Colmenares‑Quiñon confirmed the figures, noting that all 43 municipalities and component cities continue to report cases. The steep decline follows an even sharper 66‑percent drop in the first quarter alone.
The numbers are not accidental. They are the result of a province‑wide behavioral shift that began in 2025, when Ilonggos embraced aggressive household cleanup and community vigilance as routine habits. Quiñon said the downturn defied earlier worst‑case projections of over 20,000 cases. “Ang behavioral change daku gid nga bulig,” she said, crediting the sustained practice of search‑and‑destroy, early consultation, and barangay‑level alertness.
A Community That Learned to Fight Back
The province opened 2025 already at the epidemic threshold, prompting an unusually united response from barangay officials, stakeholders, and residents. That heightened vigilance prevented a feared surge even as rains persisted throughout the year. When 2026 arrived, the behavioral muscle memory was already in place—households continued emptying stagnant water, covering containers, and reporting fevers early.
The Department of Health’s “4S Kontra Dengue” strategy—Search and Destroy, Seek Early Consultation, Self‑Protection, and Support Fogging—has become second nature in many barangays. Health authorities intensified the “1‑3‑7 strategy” in areas with clustered cases, conducting fogging operations within one, three, and seven days after a reported infection. Quiñon urged residents to maintain the discipline as the rainy season approaches.
Financial Incentives Reward Zero‑Case Communities
The provincial government has backed prevention with pesos. In March 2026, 483 barangays received ₱5,000 each under Executive Order No. 162—a total of ₱2.5 million in incentives—for remaining dengue‑free from January to October 2025. The funds support vector control campaigns, health education, and capacity‑building activities at the barangay level.
Quiñon expressed hope that more barangays would join the zero‑dengue list this year, noting that the incentive program has turned disease prevention into a community competition. Cabatuan recorded the highest number of cases with 72, followed by Calinog with 59. Clusters in Barangay Merced in Banate and Barangay Oyungan in Miagao have prompted intensified monitoring. Health facilities across the province remain stocked with medicines, supplies, and larvicides, ready for any rainy‑season surge.
