The Department of Health (DOH) reported a significant decline in dengue cases across the country, with infections dropping by 56% from January to May 2026 compared to the same period last year.
Data from the DOH showed that 50,727 dengue cases were recorded during the first five months of the year, down from 114,308 cases logged in the same period in 2025.
The health department attributed the decrease to intensified community-based prevention efforts and increased public awareness on dengue control measures.
DOH Credits ‘4Ts’ Campaign for Decline
Among the key initiatives cited by the DOH is its “4Ts” campaign, which encourages households and communities to eliminate mosquito breeding sites.
The campaign stands for Taob, Taktak, Tuyo, at Takip—simple actions aimed at preventing stagnant water from becoming breeding grounds for dengue-carrying mosquitoes.
Residents are encouraged to overturn water-holding containers, remove collected rainwater from objects around the home, keep surroundings dry, and ensure water storage containers are properly covered.
According to the DOH, consistent implementation of these practices has helped reduce mosquito populations and limit the spread of dengue in many communities.
Public Reminded to Stay Vigilant During Rainy Season
The DOH also emphasized the importance of protecting oneself from mosquito bites by wearing long-sleeved clothing, long pants, socks, and closed shoes, as well as using mosquito nets and insect repellents.
At the same time, health officials urged the public to seek medical attention at the first sign of dengue symptoms, which may include high fever, skin rashes, nausea, vomiting, abdominal pain, body aches, eye pain, and nosebleeds.
As the rainy season continues, the department reminded Filipinos to remain alert not only against dengue but also other common rainy-season illnesses under the “W.I.L.D.” category—water-borne diseases, influenza-like illnesses, leptospirosis, and dengue. The DOH encouraged the public to stay informed and practice preventive measures to protect themselves and their communities.
