Philippines: dengue cases declining but concern about the rainy season

Dengue cases in the Philippines have declined for more than 10 straight weeks, but the Department of Health (DOH) warns about the potential resurgence of the disease during the rainy season. From May 4 to 17, the DOH recorded 5,900 dengue cases, a 12% drop from the 6,707 cases logged between April 20 and May 3. Despite this decline, the DOH remains cautious due to the general upward trend in 2025 cases and the seasonal risk that comes with increased mosquito breeding. The agency continues to promote vector control measures, such as draining stagnant water and covering water storage, as the most effective way to disrupt mosquito breeding cycles and prevent the spread of the disease. The DOH urged the public to take these measures seriously, especially in high-risk areas, and seek medical attention if developing dengue symptoms. Last February, the Philippine Medical Association (PMA) urged President Marcos to prioritize the approval of an advanced dengue vaccine to contain the rise of infections.
