IPHO warns of dengue risk as rains approach

By Mariela Angella Oladive

Despite lower dengue cases in Iloilo province this year, health authorities warned residents not to lower their guard, as expected rains and flooding may trigger another increase in mosquito-borne diseases.

The Iloilo Provincial Health Office said dengue transmission continues even during the dry season, noting that stagnant water in uncovered containers remains a breeding ground for disease-carrying mosquitoes.

IPHO chief Dr. Maria Socorro Colmenares-Quiñon urged residents to consistently observe anti-dengue measures regardless of weather conditions.

The province recorded 604 dengue cases and two deaths, from Ajuy and Dingle, based on the latest data from the Provincial Epidemiology and Surveillance Unit, or PESU.

Cabatuan logged the highest number of cases this year with 72, followed by Calinog with 59 and Dumangas with 25.

Other areas with relatively high counts were Janiuay with 24, Passi City and Maasin with 23 each, Oton with 21, Ajuy and Lambunao with 19 each, and Tigbauan with 18.

The warning came as the IPHO intensified its dengue and mosquito-borne disease prevention campaign from May to September 2026, following forecasts of near- to above-normal rainfall in the province.

The advisory said increased rainfall may cause flooding and stagnant water that could heighten mosquito breeding and dengue transmission.

The IPHO urged the public to strictly observe the “4S” anti-dengue strategy: search and destroy mosquito breeding sites, seek early consultation for symptoms, secure self-protection through repellents and protective clothing, and support spraying or misting operations in hotspot areas.

Residents experiencing high fever, nausea, body pain, or rashes were advised to seek medical consultation immediately.

The provincial health office also strengthened its response by activating Dengue Fast Lanes in health facilities, implementing the 1-3-7 strategy in hotspot areas, prepositioning medicines and diagnostic kits, and mobilizing Barangay Dengue Task Forces.

It also encouraged residents to join the weekly “Limpyo Iloilo Kada Lunes na Lihok Kontra Lamok” cleanup drive.

“Every clean container, every covered drum, every destroyed breeding site is a victory against dengue. Prevention is not seasonal, it must be a daily habit,” the advisory stated.
