Planning a family holiday to Florida? Whether you’re heading for the magic of Disney World, the excitement of Universal Studios, or a relaxing break on the beaches of the Florida Keys, it’s important to be aware of the growing risk of dengue fever.

While most travellers associate mosquito-borne illnesses with tropical countries, cases of dengue fever in Florida have been increasing in recent years, especially during the warmer, wetter months when mosquitoes thrive. At Fermanagh Travel Clinic, we want you and your family to enjoy your trip to the Sunshine State safely, which is why we’ve put together this guide to help you reduce your risk.

What Is Dengue Fever?

Dengue fever is a viral infection spread by Aedes mosquitoes, which bite during the daytime. The illness is common in parts of Asia, South America, and the Caribbean, but it has now become a seasonal concern in southern parts of the United States, including Florida.

While many cases are mild, dengue can lead to high fever, severe headaches, muscle and joint pain (often called “breakbone fever”), and rash. In rare cases, it can develop into severe dengue, which requires hospital care.

Why Is Dengue Fever in Florida a Risk?

Recent years have seen a rise in locally acquired dengue cases in Florida. The warm, humid climate provides the perfect breeding ground for mosquitoes, particularly in areas like:

• –> Miami-Dade County

• –> The Florida Keys

• –> Orlando and the surrounding parks

• –> Coastal cities with dense vegetation or standing water

This means even if you’re just planning to spend your days between theme parks and swimming pools, you could still be exposed to mosquitoes carrying the virus.

Who Is at Risk?

Anyone travelling to Florida, particularly during mosquito season (typically late spring to autumn), is at risk. However, those staying in areas with limited air conditioning, spending time outdoors, or visiting both urban and rural locations may be more exposed.

Families with young children, older adults, and those with weakened immune systems should be especially cautious.

How to Protect Yourself from Dengue Fever in Florida

The best protection is to avoid mosquito bites altogether.

Here are our top travel clinic tips for staying safe:

1. Use High-Quality Insect Repellent

Choose a repellent containing at least 20–50% DEET, or alternative ingredients like picaridin or lemon eucalyptus oil. Apply repellent to all exposed skin, and reapply throughout the day, especially after swimming or sweating.

We stock travel-approved repellents at Fermanagh Travel Clinic and can help you choose one suitable for the whole family.

2. Wear the Right Clothing

Dress smart when outdoors:

• –> Long sleeves and trousers can reduce exposed skin

• –> Light-coloured clothing helps deter mosquitoes

• –> Consider treating clothes with permethrin or buying pre-treated garments

This is particularly important during early morning and late afternoon when Aedes mosquitoes are most active.

3. Choose Accommodation Carefully

Opt for hotels or resorts with:

• –> Air conditioning

• –> Screens on windows and doors

• –> Mosquito nets, especially in more rural areas or older accommodation

If you’re staying in self-catered lodgings or villas, check for signs of standing water where mosquitoes might breed.

4. Be Vigilant Around Water

Avoid lingering near lakes, ponds, and areas with standing water, particularly at dawn and dusk. Use insect screens or mosquito coils when sitting outside.

Even popular destinations like Orlando’s theme parks and coastal beaches can have mosquito activity, so take precautions wherever you go.

Recognising the Symptoms of Dengue Fever

If you or a family member develops symptoms during or after your trip, seek medical advice immediately. Common signs include:

• –> High fever (sudden onset)

• –> Severe headache, especially behind the eyes

• –> Muscle and joint pain

• –> Nausea or vomiting

• –> Skin rash

• –> Bleeding gums or nose (in severe cases)

Symptoms typically appear 4–10 days after a mosquito bite, and early detection can reduce complications.

Other Travel Vaccines to Consider Before Visiting Florida

While dengue fever in Florida is a key concern, it’s also wise to review your general travel health before departure. At Fermanagh Travel Clinic, we recommend checking if you’re up to date with:

• –> Tetanus, diphtheria, and polio

• –> Hepatitis A (especially if you’re travelling more widely in the Americas or Caribbean)

• –> Influenza – especially during flu season, which can overlap with your travel dates

• –> MMR (measles, mumps, rubella) – vital with ongoing outbreaks in some areas

We’ll assess your destination, travel plans, and medical history to ensure you’re fully protected. Reach out to find out how we can keep you protected while abroad.
