But as you marvel at the historic wonders, unseen dangers buzz quietly around you. Mosquitoes—the carriers of Chikungunya—pose a real threat to your health during your travels in Thailand. Here’s what you need to know to stay safe.

What is Chikungunya?

Chikungunya is a viral infection transmitted by Aedes species mosquitoes—the same species that spreads dengue⁽¹⁾. These mosquitoes are most active during the day⁽¹⁾.

Chikungunya is found in tropical and subtropical regions worldwide, including parts of Africa, Asia, Europe, the Americas, and islands in the Indian and Pacific Oceans⁽¹⁾.

Do You Always Get Sick⁽²⁾?
Not everyone infected with Chikungunya will develop symptoms. For those who do, symptoms can range from mild to severe, making it important to know what to watch for during your travels.

Fun Fact: The name ‘Chikungunya’ comes from a Makonde word meaning ‘to become contorted,’ referring to the bent posture of patients suffering from severe joint pain—a hallmark symptom of the disease⁽³⁾.

Symptoms of Chikungunya

If you’re bitten by an infected mosquito, symptoms usually appear 3 to 7 days later⁽¹⁾. Chikungunya often begins suddenly and can be quite intense.

Common Symptoms⁽¹⁾:

• High Fever: Temperatures typically soar above 102°F (39°C).
• Severe Joint Pain: This is the most recognizable symptom, often affecting multiple joints and making movement difficult.

Other Symptoms⁽¹⁾:

• Conjunctivitis (pink eye)
• Headache
• Muscle aches
• Nausea and vomiting
• Rash (red, itchy, or patchy skin)

Recovery and Risks⁽¹⁾:
Most people recover within 7 to 10 days, but joint pain may linger for months—or even years—in some cases. Older adults and individuals with pre-existing health conditions are at higher risk of severe illness.

Important Note: Death from Chikungunya is rare but can occur in vulnerable groups, so it’s crucial to seek medical care if you suspect an infection⁽²⁾.

How to Prevent Chikungunya During Your Thailand Trip

The best defense against Chikungunya is preventing mosquito bites⁽¹⁾. Here’s how you can stay safe while exploring Thailand:

Practical Tips to Avoid Mosquito Bites⁽⁴⁾:

• Wear Protective Clothing: Pack lightweight, long-sleeved shirts and long pants, especially if you’re visiting rural areas or trekking.
• Sleep Safely: Use mosquito nets if you’re staying in less developed areas and ensure your accommodations have screened windows or air conditioning.

Chikungunya Vaccine: What You Need to Know

While prevention is key, a vaccine for Chikungunya—IXCHIQ—is now available in the U.S., Europe and Canada. Here’s what travelers need to know⁽¹⁾:

• Who Can Get It: Approved for individuals 18 years and older.
• Who Should Avoid It: Not recommended for pregnant individuals or those with weakened immune systems.
• Recommended Groups:
  • Travelers over 65, especially those with pre-existing medical conditions.
  • Those staying in Chikungunya-risk areas for 6 months or more.

What to Do If You Suspect Chikungunya

If you begin to notice symptoms of Chikungunya, it’s important to take action quickly. Here’s what you should do^(1,2):

Symptoms to Watch For:

• High fever (over 102°F or 39°C)
• Severe joint pain (often in multiple joints)
• Rash (usually appears after the fever)

Immediate Actions:

1. Seek Medical Attention:
   If you experience these symptoms, visit a medical facility in Thailand. Many hospitals and clinics in larger cities like Bangkok, Chiang Mai, and Phuket have English-speaking staff. Be sure to get checked out as soon as possible.
2. Stay Hydrated:
   It’s important to drink plenty of fluids, especially if you have a fever or are sweating excessively. This can help reduce your fever and support your immune system.
3. Manage Symptoms:
   • For Pain and Fever Relief: You can use over-the-counter medications like acetaminophen (Tylenol) to help with pain and reduce fever.
   • Avoid Ibuprofen: If there’s a chance you may also have Dengue (another mosquito-borne illness), avoid ibuprofen (Advil, Motrin) as it can increase bleeding risk.

Note: Always confirm the diagnosis with a healthcare professional to rule out other potential conditions.
