Negros Island Region (NIR) has recorded a 66 percent decline in dengue cases during the first half of 2026 compared to the same period last year, the Department of Health (DOH) reported on Monday, July 20.
The DOH NIR recorded 1,675 dengue cases from January 1 to July 4, representing a significant drop from the 4,951 cases documented during the same period in 2025.
Dengue is a viral infection transmitted to humans through the bite of infected Aedes mosquitoes. The disease causes severe flu-like symptoms and, in its acute form, can be fatal.
The 6–10-year age group recorded the highest number of dengue cases, with 278 cases (16.6 percent), followed by the 1–5-year age group with 255 cases (15.2 percent) and the 11–15-year age group with 231 cases (13.8 percent), the DOH NIR reported.
In contrast, the fewest cases were reported among infants younger than one year and adults aged 60 years and above, it said.
Males accounted for the majority of reported dengue cases, with 904 cases (54 percent), while females accounted for 771 cases (46 percent).
Of the 1,675 reported dengue cases, 527 (31.5 percent) were laboratory-confirmed through the NS1 Antigen Test, the DOH NIR said.
The remaining reports comprised 532 suspected cases (31.8 percent), 321 probable cases (19.2 percent), and 295 discarded cases (17.6 percent) that were subsequently classified as negative.
In terms of clinical classification, Severe Dengue accounted for the largest proportion of cases, with 944 cases (56.4 percent), followed by Dengue Without Warning Signs, with 711 cases (42.4 percent), the DOH NIR said.
Dengue With Warning Signs was the least common classification, with 20 cases (1.2 percent), it added.*
