Tampa Bay's Three Counties Declare Dengue Emergencies (September 25, 2026)

September 25, 2026 · 4m 56s · Listen

Hillsborough, Pasco and Pinellas have all declared dengue emergencies. So what does an emergency order actually change on the ground? This is Dengue Watch. Today: what those declarations unlock, why Seminole County is ramping up mosquito control, and a statewide CDC count that's easy to misread. We start in Tampa Bay. WUSF, with Rick Mayer:

The local emergency orders remain in effect for seven days, unless rescinded or extended.

So all three counties declared this week, per WUSF. And the thing I'd circle on the calendar is that those orders only run seven days unless they're extended or rescinded. That's the shift. We've gone from advisories to formal emergency powers. Now, an order by itself won't kill a single mosquito. It lets county administrators move fast, and it opens the door to federal resources. And the numbers are what drove it. Hillsborough added 36 locally acquired cases for the week of September 13th through 19th, according to the Florida Department of Health. Pasco and Pinellas? Counts are still low there. They're declaring to keep it from crossing the county line. That count covers September 13th through 19th. WUSF cautions that the state tally lags, so it doesn't describe infections happening today. Keep that reporting week attached to the number. Here's Mark Lehman at ClickOrlando:

Concerns about dengue fever are prompting Seminole County workers to increase mosquito control measures across the region.

Over to Seminole County, where ClickOrlando reports no confirmed dengue cases as of its September 25th story. And still, as of Sept. 24, crews have fogged more than 32,000 acres and fielded 178 service requests from residents. Fogging just means spraying a fine insecticide mist, usually at night, to knock down adult mosquitoes. They're doing it nightly there, and the reason's next door: Orange County has at least three confirmed cases, per ClickOrlando. Right, and 32,000 acres with no confirmed cases reported, some folks are gonna hear that and think overkill. ClickOrlando says crews collected more than 20,000 mosquitoes in traps last week. The county also uses an AI identification system to identify mosquito species. That's surveillance activity, not a count of infected mosquitoes or people. Those service requests and fogging totals describe the response through September 24th. They don't measure how many people have dengue. And a county reporting no confirmed cases is a different claim from knowing that no infections have occurred. From Thad Randazzo at ABC7 WWSB:

The agency cautions that the county totals show where patients live, not necessarily where they were exposed to dengue.

So the CDC table has Hillsborough at 177 cases, updated Sept. 23. And coming right after that 36 locally acquired number, I can see listeners trying to stack the two. And they shouldn't. The CDC's 392 statewide count covers Florida residents with any travel status, and it's sorted by where people live, not where the mosquito bit them. So it can't tell you how many people actually caught dengue inside Florida. Same trap with Sarasota and Manatee. They're missing from the table, but the CDC hides any county under three cases. Missing doesn't mean zero. Right. And nationally, the CDC's at 2,008 cases, with Puerto Rico at 916. It's all provisional, and the agency itself says county health departments may be more current.

Looking ahead, the seven-day emergency orders in Hillsborough, Pasco and Pinellas run out around Sept. 30 to Oct. 1 unless the counties extend or rescind them. And the Florida Department of Health's next weekly arbovirus report, expected Thursday, Oct. 1, will update locally acquired case counts by county.
