Dengue cases in Philippines continue to decline, but DOH warns of rainy season spike

Published Jun 17, 2025 07:15 pm
Dengue cases in the country have declined for more than 10 straight weeks, the Department of Health (DOH) reported on Tuesday, June 17.
However, the agency cautioned that dengue infections may rise again with the arrival of the rainy season.
From May 4 to 17, the DOH recorded 5,900 dengue cases, marking a 12 percent drop from the 6,707 cases logged between April 20 and May 3.
Despite this sustained decline, the health department said it remains cautious due to the overall upward trend in 2025 cases and the seasonal risk that comes with increased mosquito breeding.
“Dengue cases in the Philippines continue their downward trend for over 10 consecutive weeks,” the DOH said.
“With the rainy season now upon us, the numbers are expected to rise.”
The agency said it continues to push for vector control as the most effective form of prevention, reiterating its advocacy campaigns: “Taob, Taktak, Tuyo, Takip” and “Alas-kwatro kontra mosquito.”
The campaigns focus on simple, routine household actions, such as draining stagnant water and covering water storage, to disrupt mosquito breeding cycles.
As such, the DOH reported that Dengue Serotype 3 (DENV-3) remains the most prevalent strain, accounting for 33 percent of tested cases.
It is followed by Serotype 1 (DENV-1), which makes up 27 percent.
The agency urged the public to take preventive measures seriously, especially in high-risk areas, and to seek early medical attention if dengue symptoms appear.
In February, the Philippine Medical Association (PMA) urged President Marcos to prioritize the approval of an advanced dengue vaccine, as the country faced a sharp rise in infections.
