Dengue Cases Surge Across Florida, Central America, and the Philippines in 2026
8/29/2026, 4:59:31 AM
Core Event
In 2026 dengue fever cases have risen sharply in multiple regions, prompting intensified mosquito-control efforts and public-health advisories. In Florida, CDC provisional data show increases in several counties, while local health agencies report confirmed locally acquired cases. Costa Rica’s Ministry of Health records a 30 % year-over-year rise, and the Cebu Provincial Health Office (PHO) notes a surge that has already exceeded the previous year’s totals.
Background & Context
Dengue is transmitted by the Aedes aegypti mosquito and is endemic in tropical and subtropical areas. In Florida most cases have historically been imported; local transmission occurs when an infected traveler is bitten by a resident mosquito. Seasonal rains from May through October create optimal breeding conditions.
Data & Statistics
| Region | Reported Cases (2026) | Notable Trends |
|---|---|---|
| Florida (CDC provisional) | 1,575 nationwide; county increases include Hillsborough (20 -> 36), Miami-Dade (49 -> 67), Broward (11 -> 12) | Some counties remain in a “1 to 4” range, obscuring exact changes. |
| Florida (Pasco County Mosquito Control) | 30 locally acquired cases in Hillsborough, 3 in Pinellas, 1 in Citrus | Positive Aedes aegypti pools identified. |
| Costa Rica (Ministry of Health) | >3,400 through EW 32, a 30 % increase over 2025 | Central Pacific region reports 240.2 cases per 100,000; >2.4 million breeding sites treated. |
| Cebu Province, Philippines (PHO) | 2,324 cases and 17 deaths (Jan–mid-Aug) | Talisay (272 cases) among hardest-hit municipalities. |
Official Statements & Responses
- The CDC notes its surveillance data are provisional and reported by patients’ county of residence.
- The Florida Department of Health emphasizes most cases are imported but warns returning travelers can seed local transmission.
- Pasco County Mosquito Control District urges residents to eliminate standing water, use EPA-registered repellents, and keep screens intact.
- Costa Rica’s Ministry of Health reports vector-control teams have visited nearly 400,000 homes and treated more than 2.4 million potential breeding sites.
- The Cebu Provincial Health Office has activated a dengue council and promotes “Search and Destroy” clean-up drives, using fogging only as a last resort.
On-the-Ground Reports
- In Tampa Bay, Pasco County officials confirmed locally acquired cases and dengue-positive mosquito pools.
- Costa Rican health workers reported five hospitalizations, including one at Hospital San Rafael in Alajuela.
- Cebu officials highlighted stagnant water in flower vases, gutters and containers as key breeding sites during the rainy season.
Conflicting Reports & Gaps
- CDC county-level data list some counties in a “1 to 4” range, preventing precise assessment, while local Florida departments provide exact counts for certain counties.
- The total of 1,575 U.S. cases is provisional; state and local agencies may have more current figures.
- Costa Rica’s count is presented as “over 3,400,” lacking an exact final number beyond epidemiological week 32.

What’s Next
- The CDC will continue updating its provisional dengue surveillance.
- Florida health officials plan to maintain heightened mosquito surveillance throughout the peak season.
