A Tampa woman died of dengue fever in September.
That was the first dengue fever death in that city in nearly a century.
But Florida just hit a 90-year record for Dengue Fever – and most people living there have no idea.
The Worst Outbreak Since the Great Depression
America hasn’t seen anything like this since the 1930s.
The last time Florida recorded a dengue outbreak of this scale was 1934 – when more than 15,000 Floridians fell sick across 70 counties.
That epidemic ended through aggressive mosquito eradication campaigns, widespread drainage projects, and the adoption of window screens.
For 90 years, dengue was something you caught on a trip to the tropics.
It wasn’t something you caught mowing your lawn in Tampa.

That calculation just changed.
The Florida Department of Health confirmed 485 locally acquired cases this year – the worst numbers for any state since at least the 1940s.
In the week ending October 24 alone, 60 new infections were recorded.
The Tampa Bay area accounts for roughly 95% of all cases statewide, with Hillsborough, Pasco, and Pinellas counties all declaring local states of emergency in late September.
Hillsborough has since extended that declaration as transmission continues.
What You’re Dealing With and Why It’s Dangerous
Dengue is not the flu.
The Aedes aegypti mosquito – the species driving this outbreak – doesn’t bite at dawn and dusk like the mosquitoes you’re used to.
It feeds aggressively during the day.
It thrives in the warm, humid residential environments that make Florida living attractive.
And unlike most Florida mosquitoes, it doesn’t travel far – which means infections concentrate in neighborhoods where the virus has already taken hold.
The virus causes fever, severe muscle and joint pain so intense it earned the nickname “breakbone fever,” nausea, and rash.
Most infected people either have no symptoms or recover within two weeks.

But a small percentage develop severe dengue – and that phase can emerge within 24 to 48 hours after the initial fever drops.
That window – when patients feel like they’re getting better – is exactly when the danger escalates.
When someone suddenly develops severe abdominal pain, starts vomiting repeatedly, or shows unusual bleeding and extreme fatigue after a fever breaks, get them to an emergency room.
Gay Small – an 80-year-old Tampa woman – died on September 4, within a week of her diagnosis.
Health officials confirmed her as Florida’s first dengue fatality of 2026 and the first dengue death recorded in Tampa Bay in nearly 100 years.
What You Need to Do Right Now
The mosquitoes driving this outbreak are container breeders.
They don’t need a pond or a creek.
They need a tablespoon of standing water.
A clogged gutter.
A birdbath you haven’t drained in two weeks.
An old tire sitting behind the shed.
A bottle cap left in the yard.
Walk your property weekly and eliminate anything that holds water.
Use EPA-registered repellents containing DEET, picaridin, or oil of lemon eucalyptus – applied after sunscreen, not before.
Loose-fitting, light-colored long sleeves and pants cut your exposure when you’re outside during the day.
Mosquito control crews across the Tampa Bay area have ramped up ground spraying, aerial applications, and property inspections.

But government spraying can only do so much.
The real defense starts in your backyard.
This Isn’t Going Away
A Tulane University expert who studies dengue told reporters that most Tampa residents have no prior immunity to any form of the virus – which means the local population offers it little resistance.
Florida also logged more than 300 travel-associated dengue cases this year on top of the 485 locally acquired ones.
That number matters more than health officials are letting on.
Every one of those travel cases is a potential bridge between a dengue-endemic country and your neighborhood mosquito population.
A returning traveler gets bitten by a local mosquito before symptoms appear.
That mosquito bites your neighbor.
Your neighbor’s yard breeds the next generation of infected mosquitoes.
The 1934 epidemic ended because Americans went to war with the mosquito – and won.
The tools today are more sophisticated: aerial spraying, targeted larvicides, genetic mosquito control programs.
But the population is larger, the suburbs are more sprawling, and travel patterns make re-introduction a constant threat.
The experts who study this for a living are now saying dengue outbreaks in Florida are the new normal.
Not a once-in-a-generation event.
If you live in or are traveling to the Tampa Bay area, see a doctor immediately if fever, severe joint pain, or rash develops after any daytime mosquito exposure.
Don’t wait and see.
