You’ve been dreaming of witnessing the breathtaking sunrise at Angkor Wat, the world’s largest religious monument. As the golden light spills over the ancient stone, it’s a magical moment—but hidden in the morning air are mosquitoes that could carry dengue fever.

Dengue Fever in Cambodia: What Travelers Need to Know
Dengue fever is a viral illness spread by infected mosquitoes, primarily Aedes aegypti and Aedes albopictus(1). These mosquitoes also transmit Chikungunya and are most active during the day, with peak activity occurring in the early morning and late afternoon(1).
Where is Dengue Found?
Dengue is common in tropical and subtropical regions, including(1):
- Southeast Asia (ex. Cambodia, Thailand, Vietnam)
- Central and South America
- Caribbean
- Africa
- Pacific Islands
In Cambodia, the risk is highest during the rainy season (May–October) when standing water creates perfect mosquito breeding grounds(1).
Do You Always Get Sick from Dengue?
Not everyone who gets dengue shows symptoms. Up to 80% of infections are mild or asymptomatic. But when symptoms do appear, they can be severe(1).
Dengue Fever Symptoms (Appear 4-10 days after a mosquito bite)(1,2)
- High fever (often above 104°F or 40°C)
- Severe headache
- Pain behind the eyes
- Muscle and joint aches (often referred to as “breakbone fever”)
- Nausea and vomiting
- Skin rash (can appear a few days after fever)
When to Seek Emergency Care
If you experience severe abdominal pain, persistent vomiting, bleeding gums/nose, or difficulty breathing, seek immediate medical attention. Severe dengue can be life-threatening(1,2).
Packing Checklist for Mosquito Protection in Cambodia
