DOH-1 urges intensified dengue fight with '4 o'clock habit'

The Department of Health in Ilocos Region (DOH-1) is urging local government units and agencies to intensify efforts against dengue by conducting daily mosquito-breeding site elimination activities at 4 p.m., a practice known as the '4 o'clock habit'.

DOH-1 Director Paula Paz Sydiongco emphasized the importance of this habit for personal and family protection, highlighting that the fight against dengue requires everyone's active participation.

To support these initiatives, the regional office provided LGUs with anti-dengue supplies in July 2024, such as misting machines, backpack sprayers, insecticides, and Olyset nets.

The Regional Epidemiology and Surveillance Unit reported a substantial increase in dengue cases in DOH-1, with 884 recorded from January 1 to February 15, 2025, which is double the 441 cases from the same period in 2024.

Meanwhile, the Provincial Health Office (PHO) in Negros Oriental is also urging local government units (LGUs), schools, and other institutions to strengthen measures against dengue, particularly the 4 o'clock habit.

PHO chief Dr. Liland Estacion stated that 2025 is an 'epidemic year' based on a three-year cycle where dengue outbreaks are reported, and while Negros Oriental has logged a decrease in cases (430 from Jan. 1 to Feb. 22, 2025, vs. 473 in the same period last year), they are monitoring for a potential spike.

Estacion also noted that the 4 o'clock habit is complementary to other measures such as misting operations and the provision of chemically-treated nets and screens.
