The Rise of Dengue Fever in the Tampa Bay Area

Dengue fever is becoming an increasingly important mosquito-borne disease concern in the Tampa Bay area. In 2026, locally acquired dengue cases have been confirmed in both Hillsborough and Pinellas counties, highlighting the importance of mosquito awareness and prevention for Florida residents.

Key Takeaways

• Dengue fever is primarily transmitted by infected Aedes mosquitoes, including Aedes aegypti and Aedes albopictus, both of which are found in Florida.
• Symptoms can include fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting and rash. Most people recover, but severe dengue can become a medical emergency.
• Reducing mosquito populations and preventing bites are the most effective defenses. Eliminating standing water, using insect repellent and professional mosquito control services can help reduce mosquito exposure around your property.

Why Dengue Fever Is a Growing Tampa Bay Concern

Dengue is not new, but its appearance through locally acquired cases deserves attention in the Tampa Bay area.

In August 2026, the Florida Department of Health in Hillsborough County announced an eighth confirmed locally acquired case of dengue fever and continued its mosquito-borne illness alert. Pinellas County also issued a mosquito-borne illness alert after confirming two locally acquired dengue cases.

“Locally acquired” is particularly significant. It means the infected individuals did not simply contract dengue while traveling to another country or region where the disease is common. Local transmission indicates that mosquitoes in the area have been involved in transmitting the virus.

Most dengue cases in the continental United States historically occur among travelers infected elsewhere, but local transmission can occur when mosquitoes capable of carrying the virus are present.

Florida’s warm temperatures, rainfall and mosquito populations make mosquito prevention particularly important.

What Is Dengue Fever?

Dengue is a viral illness caused by one of four related dengue viruses.

The disease occurs throughout tropical and subtropical regions and is transmitted primarily through infected mosquitoes. Because four dengue virus types exist, a person can be infected more than once during their lifetime.

According to the CDC, about one in four people infected with dengue develops symptoms. A smaller percentage of symptomatic patients develop severe dengue.

How Is Dengue Fever Spread?

Aedes Mosquitoes Are the Primary Vector

Dengue is mainly transmitted through bites from infected Aedes mosquitoes, particularly:

• Aedes aegypti, commonly known as the yellow fever mosquito
• Aedes albopictus, commonly known as the Asian tiger mosquito

These mosquitoes can also transmit viruses responsible for illnesses such as Zika and chikungunya.

The transmission cycle typically begins when a mosquito bites someone who has dengue virus circulating in their blood. The mosquito becomes infected and can later transmit the virus when it bites another person.

Unlike some mosquitoes that are primarily active around dawn or dusk, dengue-carrying Aedes mosquitoes can bite during both the day and night.

Where Do Aedes Mosquitoes Breed?

Aedes mosquitoes commonly lay eggs in or around containers that collect water.

Potential breeding locations around Tampa Bay homes and businesses include:

• Flowerpots and plant saucers
• Buckets
• Birdbaths
• Clogged gutters
• Outdoor toys
• Trash containers
• Wheelbarrows
• Decorative containers
• Other objects capable of collecting rainwater

Florida’s frequent rainfall makes routine property inspections especially important.

What Are the Symptoms of Dengue Fever?

Dengue symptoms generally develop within about two weeks of being bitten by an infected mosquito.

The most common symptom is fever accompanied by one or more of the following:

• Severe headache
• Pain behind the eyes
• Muscle pain
• Joint or bone pain
• Nausea
• Vomiting
• Rash

Because these symptoms can resemble other illnesses, you should not attempt to diagnose dengue based on symptoms alone.

If you develop fever or other symptoms consistent with dengue—particularly following travel to an area where dengue occurs or during a period of identified local transmission—contact a healthcare provider.

What Is Severe Dengue?

Most people with symptomatic dengue recover, but some infections can progress to severe dengue, which is a medical emergency.

Warning signs can include:

• Severe abdominal pain or tenderness
• Persistent vomiting
• Bleeding from the nose or gums
• Blood in vomit or stool
• Extreme tiredness
• Restlessness or irritability

Importantly, warning signs of severe dengue can develop as a person’s fever begins to disappear.

Anyone experiencing potential warning signs should seek immediate medical care.

How Is Dengue Fever Treated?

There is currently no specific antiviral medication for dengue. Treatment focuses primarily on supportive care.

For uncomplicated cases, medical guidance may include:

• Getting plenty of rest
• Drinking fluids to prevent dehydration
• Using acetaminophen to reduce fever and pain when medically appropriate
• Monitoring carefully for warning signs of severe disease

The CDC advises people with suspected dengue not to take aspirin or ibuprofen, because these medications can increase the risk of bleeding.

A healthcare professional should evaluate suspected dengue and provide treatment recommendations appropriate to the individual patient.

What Is the Typical Outcome of Dengue?

The outlook for most dengue patients is favorable. Symptoms typically last two to seven days, and most people recover in approximately a week.

However, severe dengue can develop quickly and can be life-threatening. Prompt recognition of warning signs and appropriate supportive medical treatment significantly improve outcomes.

Another important consideration is reinfection. Infection with one dengue virus type does not provide lifelong immunity against all four dengue virus types, so people can contract dengue more than once.

How Can Tampa Bay Residents Help Prevent Dengue?

There is no single mosquito-control measure that completely eliminates dengue risk. Prevention works best through a combination of personal protection and mosquito management.

1. Eliminate Standing Water

Inspect your property regularly and remove water that has collected in containers.

Empty and clean birdbaths, flowerpot saucers and other water-holding containers. Keep gutters flowing freely and address drainage problems when possible.

2. Use EPA-Registered Mosquito Repellent

When spending time outside, use an EPA-registered insect repellent according to its label directions.

3. Wear Protective Clothing

Loose-fitting long sleeves and long pants can reduce exposed skin when mosquito activity is high.

4. Keep Mosquitoes Out of the Home

Repair damaged window and door screens and keep doors closed when possible.

5. Remember That Aedes Mosquitoes Bite During the Day

Do not assume mosquito protection is only necessary in the evening. The Aedes species responsible for dengue transmission can bite during daytime and nighttime hours.

6. Protect Others If You Have Dengue

Someone infected with dengue should continue avoiding mosquito bites, particularly during the first week of illness.

A mosquito that bites an infected person can potentially become infected and later transmit dengue to someone else.

Professional Mosquito Control Can Be Part of Your Prevention Strategy

Reducing mosquito breeding and activity around a property can be an important component of a broader mosquito-bite prevention strategy.

Rodent Solutions’ mosquito control services are available for homes and businesses in Bradenton, Sarasota, Lakewood Ranch, Parrish and surrounding areas.

Rodent Solutions begins its mosquito service by identifying potential breeding areas and determining appropriate placement of mosquito-control stations. The company’s mosquito-control program specifically targets Aedes mosquitoes—the group that includes the species capable of transmitting dengue.

The stations are serviced regularly, and Rodent Solutions also focuses on breeding locations around the property.

For more information about mosquitoes found in Florida, visit the Rodent Solutions mosquito pest-control resource or browse the Pest Library.

Professional mosquito management cannot guarantee that a person will never be bitten or contract a mosquito-borne disease. It should instead be used alongside personal protective measures, standing-water reduction and public-health recommendations.

Why Mosquito Control Matters Beyond Dengue

Dengue is only one reason Florida property owners should take mosquito activity seriously.

Mosquitoes can act as disease vectors, and different species can transmit different pathogens. Effective mosquito management can also make patios, pools, yards and other outdoor living spaces considerably more comfortable.

For Tampa Bay-area property owners, mosquito prevention should therefore be viewed as an ongoing property-management practice rather than something to consider only after mosquito populations become overwhelming.

Frequently Asked Questions About Dengue Fever in Tampa Bay

Can you catch dengue fever from another person?

Dengue is primarily transmitted through the bite of an infected Aedes mosquito rather than ordinary person-to-person contact. A mosquito can bite a person with dengue virus in their blood, become infected and later transmit the virus to another person. Rare non-mosquito transmission routes have also been documented.

What are the first symptoms of dengue fever?

Dengue commonly causes fever along with headache, pain behind the eyes, muscle, joint or bone pain, nausea, vomiting or rash. Symptoms generally develop within about two weeks after an infected mosquito bite. Because dengue can resemble other illnesses, anyone concerned about symptoms should contact a healthcare provider.

Can dengue fever be fatal?

Most people with dengue recover, often within approximately a week, but some patients develop severe dengue. Severe dengue can cause shock, serious bleeding or organ impairment and is a medical emergency. Severe abdominal pain, persistent vomiting, bleeding or significant changes in alertness require prompt medical evaluation.

How can I reduce dengue-carrying mosquitoes around my home?

Start by eliminating standing water from buckets, flowerpots, gutters, birdbaths and other containers. Maintain window and door screens and use EPA-registered mosquito repellent when outdoors. Professional mosquito control can complement these precautions by identifying breeding locations and reducing mosquito populations around a property.

Does Rodent Solutions provide mosquito control?

Yes. Rodent Solutions provides professional mosquito control in Bradenton, Sarasota, Lakewood Ranch, Parrish and surrounding Florida communities. Its program includes identifying potential breeding locations and deploying mosquito-control stations designed to target mosquitoes, including Aedes species associated with dengue, Zika, yellow fever and chikungunya transmission.

Take Mosquito Prevention Seriously

The locally acquired dengue cases reported in the Tampa Bay area are a reminder that mosquito-borne illnesses are not exclusively an overseas concern.

Property owners can help reduce mosquito exposure by eliminating standing water, using appropriate personal protection and addressing mosquito populations before they become severe.
