What is Japanese Encephalitis?

Japanese Encephalitis (JE) is a potentially severe viral brain infection spread by mosquitoes, particularly in rural parts of Asia. While rare in short-term travellers, infection can lead to long-term neurological damage or even death in severe cases.

  • Caused by the Japanese Encephalitis virus (JEV) 
  • Transmitted by the Culex mosquito, typically in rice fields or pig farming areas 
  • There is no specific treatment once infected 
  • Up to 30% of severe cases can result in death; others may suffer long-term neurological damage

Where Is Japanese Encephalitis a Risk?

Japanese Encephalitis is found in many parts of Asia and the Western Pacific. Risk varies depending on location, season, and travel activities. Regions where JE is endemic include:  

  • Southeast Asia – Thailand, Vietnam, Indonesia, Cambodia, Laos, Malaysia, Myanmar, Philippines
  • East Asia – China, Taiwan, Japan, South Korea
  • South Asia – India, Nepal, Sri Lanka
  • Australasia – Papua New Guinea, Northern Australia

High-risk areas include rural or agricultural zones, especially those with rice paddies, pig farming, or stagnant water, ideal mosquito breeding sites. Risk typically increases during the rainy or monsoon season, but transmission can occur year-round in tropical climates.

Is JE Vaccine Required for My Trip?

The Japanese Encephalitis vaccine is generally not mandatory for entry into any countries, but it is strongly recommended for certain types of travellers and destinations.

You may benefit from the vaccine if you: 

  • Plan to stay in rural or agricultural areas (e.g. villages, rice fields, pig farms)

  • Will be spending time outdoors, especially for activities like hiking, biking, or camping

  • Are travelling during the rainy or mosquito season, when risk is highest

  • Will be in a high-risk country for more than 30 days

  • Are visiting an area with a known JE outbreak

  • Are bringing young children or have a weakened immune system

Even if your trip is less than 30 days, vaccination may still be advised if your itinerary includes:

  • Overnight stays in rural or outdoor settings

  • Exposure to standing water or livestock farms

  • Minimal use of air-conditioning or insect protection

  • Travel to endemic areas during peak transmission season


You may not need the vaccine if you:

  • Are staying only in urban cities

  • Will be in an endemic region for a short stay with no mosquito exposure

  • Are spending most of your time indoors or in air-conditioned environments

During your travel consult, our GP will review your destinations, activities, and health profile to determine if JE vaccination is advisable.

Always check with the destination embassy, CDC, or MOH Singapore for the latest requirements.

Japanese Encephalitis Vaccine Related

Do I need a Japanese encephalitis vaccine for travel?
It depends on your destination, duration, and activities. It is recommended for travellers visiting rural or high-risk areas.
How long before travel should I get vaccinated?
For Imojev®, you should get vaccinated at least 30 days before travel.
How long does the Imojev vaccine last?
The Imojev vaccine provides protection for at least 10 years.
Is the Japanese encephalitis vaccine necessary?
It is not mandatory, but strongly recommended for travellers at risk of mosquito exposure.
Can I take the JE vaccine with other travel vaccines?
Yes, in many cases. Our doctor will advise based on your travel plans.
Can pregnant women take the JE vaccine?
Generally not recommended unless travel is unavoidable. Please consult our doctor on this.
Does the vaccine guarantee full protection?
No vaccine provides 100% protection. Mosquito precautions are still important.

The Japanese encephalitis (JE) vaccine protects against Japanese encephalitis, a mosquito-borne viral infection that can cause serious brain inflammation.

While uncommon in short-term travellers, the illness can be very severe—sometimes leading to long-term neurologic problems and, in rare cases, death.

Where is JE found?
The virus is present in many parts of Asia and the western Pacific. Risk depends on your destination, time of year, and planned activities. It is more common in rural or farming areas—especially near rice fields, pig farms, or stagnant water where mosquitoes breed. Risk usually increases during the rainy/monsoon season, though transmission can occur year-round in tropical climates.

Who should consider the vaccine?

  • Travellers staying in rural/farming areas (villages, rice paddies, pig farms)
  • Those spending a lot of time outdoors or travelling during peak mosquito season
  • Trips > 30 days in a higher-risk country, or visits to areas with known outbreaks
  • Young children, individuals with weaker immune systems, or anyone with overnight stays in rural areas
  • Itineraries with exposure to livestock or standing water, minimal air-conditioning, or limited mosquito protection

Who may not need it?
Travellers visiting only major cities, staying mostly indoors, or making a very short visit with minimal mosquito exposure may not require vaccination.

Bottom line
The Japanese encephalitis vaccine is a simple and effective way to reduce your risk during travel.
