Traveling to the Tropics in 2026

Tropical travel is booming. Destinations like Bali, Costa Rica, Thailand, and the Caribbean are topping travelers' bucket lists. But while dreamy beaches, lush rainforests, and vibrant cultures await, so do health risks that many travelers underestimate or ignore entirely.

Tropical regions are home to a host of diseases and environmental challenges that can turn your getaway into a nightmare if you’re not prepared. Here’s what you need to know about staying healthy while traveling in the tropics—and how Generali Global Assistance can help if things go wrong.

Why Tropical Travel Requires Extra Health Precautions

While COVID-19 is no longer the dominant concern it once was, global travelers are still encountering health risks—many of which are exacerbated by climate change, deforestation, and the growing reach of disease-carrying insects.

Recent studies show that travelers to tropical and subtropical areas are at significantly higher risk of contracting infectious diseases, especially in rural areas where access to medical care is limited. The U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) regularly update travel advisories for mosquito-borne illnesses, foodborne infections, and water-related hazards.

Top Tropical Diseases Travelers Need to Know

1. Dengue Fever: On the Rise

Dengue, once limited to Southeast Asia and Latin America, is spreading rapidly due to warming climates and increased urbanization. According to the WHO, 2024 saw record-high outbreaks in countries like Brazil, Bangladesh, and Peru, with over 4.2 million reported cases worldwide.

Symptoms: High fever, severe headache, muscle and joint pain, rash, and in some cases, internal bleeding.
Prevention: Wear long sleeves, use insect repellent with DEET or Picaridin, and stay in screened or air-conditioned rooms.
Symptom management: Treatment focuses on hydration and pain relief.

2. Malaria: Still a Major Threat in Sub-Saharan Africa and Parts of Asia

Despite medical advancements, malaria remains deadly, particularly in regions like West Africa, Papua New Guinea, and parts of India according to the National Library of Medicine.

Good news: The RTS,S malaria vaccine is being rolled out in high-risk areas, and a second vaccine, R21/Matrix-M, received WHO approval in late 2023.
Bad news: Drug-resistant strains are emerging in Southeast Asia according to the CDC.
Travel tip: Talk to your doctor about antimalarial medication before departure. Be aware of side effects and consider travel protection from Generali Global Assistance.

3. Chikungunya and Zika: Still Circulating

While Zika outbreaks have slowed significantly, the virus still circulates in tropical regions. Chikungunya, spread by the same Aedes mosquito, causes debilitating joint pain that can last for months.

Zika remains a concern for pregnant travelers due to potential risks.
Chikungunya cases are rising in the Caribbean and parts of Africa.
Prevention: As with dengue, the key is avoiding mosquito bites.

4. Tick-Borne and Other Vector Diseases

Even in the tropics, it’s not just mosquitoes that pose risks:

Tick-borne illnesses like African Tick Bite Fever and Tick-Borne Encephalitis are common in certain rural and forested areas.
Chagas Disease, caused by the triatomine bug, is found in Central and South America and can lead to serious heart and digestive issues.

5. Water-Related Illnesses

Diseases like leptospirosis (from animal-contaminated water) and schistosomiasis (caused by parasites carried by freshwater snails) are common in tropical countries after flooding or during rainy seasons.

To reduce risk:

Don’t swim in freshwater lakes or rivers unless you’re sure it’s safe.
Drink only bottled, filtered, or boiled water.
Avoid street food unless it's piping hot and freshly cooked.

6. Gastrointestinal Issues: Not Always a “Disease”

Many travelers blame illness on contaminated food, but gastrointestinal (GI) issues can also stem from dietary changes. Spicy, oily, or unfamiliar ingredients can overwhelm your system.

Other Tropical Travel Hazards

It’s not just disease that can derail a trip:

Heat exhaustion and dehydration in humid climates
Injuries from adventure activities like hiking, snorkeling, or riding motorbikes
Natural disasters, such as monsoons, hurricanes, or volcanic activity
