Planning a family trip to Asia or the Western Pacific? While exploring rice paddies, temples, or jungles, mosquito bites might be the last thing on your mind—but Japanese Encephalitis (JE) is a real risk in rural areas. At Aqua Travel Clinic, we’ve helped hundreds of families travel safely. Here’s what parents need to know.
What is Japanese Encephalitis?
JE is a serious viral infection spread by mosquitoes in rural parts of Asia and the Pacific. Most cases are mild, but 1 in 250 infections leads to brain swelling (encephalitis), which can be fatal or cause long-term disability. Children are at higher risk due to developing immune systems.
Does My Child Need the JE Vaccine?
Yes, if your trip includes:
✅ Rural areas (farms, rice fields, jungles) in countries like Thailand, Vietnam, or India.
✅ Long stays (≥1 month) in regions with active JE transmission.
✅ Outdoor activities (camping, hiking, biking) during dusk/dawn when mosquitoes bite.
Not usually needed for:
-
Short city trips (e.g., Bangkok, Tokyo).
-
Travel during dry seasons with fewer mosquitoes.
