Dengue Cases Rise in Philippines While Declining in Brazil in 2026

In the Philippines, dengue infections in the municipality of Benguet rose by 50 % in the first half of 2026, with 54 cases recorded between 4 January and 20 June compared with 36 a year earlier. No dengue‑related deaths were reported. Local health officials urged residents to follow the Department of Health’s 4S Kontra Dengue strategy—searching for and destroying mosquito breeding sites, using protective clothing, nets and repellents, and seeking prompt medical care.

In Brazil, the city of Sorocaba reported a dramatic drop in dengue cases, confirming only 62 infections in mid‑2026—a 99 % reduction from previous seasonal levels—and zero fatalities. Authorities credited intensified vector‑control measures, including aggressive mosquito‑abatement programs and integrated pest‑management actions that eliminated stagnant water reservoirs. The decline was echoed in neighboring municipalities, highlighting the effectiveness of sustained environmental management and early clinical intervention.
