BUTUAN CITY, Philippines — Dengue infections across the Caraga Region have fallen sharply in 2026, but health authorities are warning residents not to interpret the dramatic decline as a signal that the threat has disappeared.
Latest Department of Health-Caraga figures showed 2,303 dengue cases as of August 8, about 66 percent lower than the 6,822 cases recorded during the comparable period in 2025.
The numbers represent one of the region’s most substantial year-on-year improvements in dengue infections. But behind that headline is a more complicated picture: Agusan del Sur has recorded the largest number of cases in Caraga and was recently among the areas nationwide that breached the dengue epidemic threshold.
That is why the Department of Health is urging families to seek medical attention early rather than waiting for symptoms to become severe.
Dr. Amethyst Kathleen Alicante, medical officer IV of DOH-Caraga, said residents who develop possible dengue symptoms should immediately consult a rural health unit or other health facility. Hospitals across the region have also been placed on alert and prepared to handle dengue patients, according to the agency.
Agusan del Sur leads Caraga dengue cases
The latest regional breakdown paints a clearer picture of where infections are concentrated.
As of August 8, Agusan del Sur had recorded 674 cases, by far the highest among Caraga’s provinces.
It was followed by:
- Surigao del Sur — 431
- Surigao del Norte — 280
- Agusan del Norte — 106
- Dinagat Islands — 100
Among the region’s cities, Butuan City recorded 214 cases, followed by Tandag City with 139, Bayugan City with 129, Surigao City with 104, Cabadbaran City with 67, and Bislig City with 59.
Of Caraga’s 2,303 reported infections, 621—or about 27 percent—were laboratory-confirmed through tests including PCR, viral isolation, NAAT-LAMP or dengue NS1 testing, according to PIA’s report citing DOH-Caraga.
The decline has been dramatic—but the numbers are still moving
Caraga’s dengue trend has changed significantly throughout the year.
During the first half of 2026, DOH-Caraga reported just 1,081 cases, down from 4,127 during the comparable 2025 period—a 74 percent decline.
By July 25, however, the cumulative total had risen to 1,813 cases, compared with 5,813 a year earlier.
And by August 8, infections had climbed to 2,303.
The year-on-year picture therefore remains substantially better than in 2025, but the steady addition of new cases reinforces the DOH’s warning that communities cannot afford to become complacent.
The rainy season is particularly important because standing water can create breeding sites for Aedes mosquitoes, the insects responsible for transmitting dengue.
Agusan del Sur raises a warning flag
Perhaps the most important detail behind Caraga’s 66-percent regional decline is what is happening in Agusan del Sur.
National surveillance data covering July 5 to August 1 identified Agusan del Sur among Philippine provinces and cities that had breached the dengue epidemic threshold.
An epidemic threshold generally indicates that dengue activity in an area has risen beyond the level normally expected, triggering intensified surveillance and public-health intervention.
That means Caraga can simultaneously record a major regional decline compared with last year while still experiencing serious localized outbreaks.
It is a crucial distinction for residents: a falling regional average does not necessarily mean every province or municipality is experiencing the same trend.
Nationwide cases are also down—but dengue remains a threat
Caraga’s improvement mirrors a broader national decline.
DOH surveillance figures reported by The Philippine Star showed 93,155 dengue cases nationwide from January 4 to August 1, 2026, down 46 percent from 174,077 cases during the same period in 2025.
Dengue-related deaths also fell, from 699 in the comparable 2025 period to 386 this year.
But several areas around the country have nevertheless crossed alert or epidemic thresholds, demonstrating that the national decline does not eliminate the possibility of local surges.
The situation has prompted the national government to strengthen preparations during periods of heavy rain. On August 10, President Ferdinand Marcos Jr. ordered the DOH to monitor dengue and leptospirosis closely and activate dedicated fast lanes in DOH hospitals and Bagong Urgent Care and Ambulatory Service centers.
DOH: Don’t wait until dengue becomes severe
Health authorities say early consultation remains one of the most important defenses against serious complications.
Possible dengue symptoms can include fever, headache, muscle or joint pain, nausea, vomiting and skin rashes. People experiencing suspected symptoms are being urged to seek assessment at an RHU, health center or hospital instead of attempting to simply wait out the illness at home.
DOH-Caraga continues to promote its 4S strategy:
Search and destroy mosquito breeding places;
use Self-protection measures such as repellents and protective clothing;
Seek early consultation when symptoms appear; and
Support fogging or spraying in hotspot areas when medically indicated.
Families are also being encouraged to practice the “taob, taktak, tuyo at takip” routine—turning over or emptying containers, removing accumulated water, keeping potential breeding areas dry and covering water containers.
The message from health officials is straightforward: Caraga’s 66-percent decline is encouraging, but dengue has not disappeared.
With more than 2,300 infections already recorded and Agusan del Sur reaching the epidemic threshold in recent surveillance, the bigger test may be whether communities can sustain prevention efforts through the remainder of the rainy season.
A lower case count is progress.
Keeping it low is the harder part.
