Japanese encephalitis is a serious infection caused by a virus spread through mosquito bites. It is more common in parts of Asia and the Western Pacific, but UK travellers heading to these regions are at risk too. Though rare, Japanese encephalitis can cause inflammation of the brain, which may lead to severe complications or even death. Understanding how to protect yourself is key to staying safe while travelling.
What Is Japanese Encephalitis?
Japanese encephalitis is caused by the JE virus, a mosquito-borne virus mainly found in rural and farming areas of Asia. While many people infected with the virus show no symptoms, a small number can develop serious illness.
The virus is most common in countries like India, China, Thailand, Vietnam, and Indonesia, especially during the rainy season when mosquitoes breed.
Symptoms of Japanese Encephalitis
Most people infected with the Japanese encephalitis virus have no signs of illness. However, in rare cases, symptoms appear suddenly and can include:
- High fever
- Headache
- Stiff neck
- Confusion
- Seizures
- Difficulty moving or speaking
These symptoms are due to inflammation of the brain (encephalitis), which can be life-threatening. Sadly, even those who survive may suffer from long-term complications such as memory problems, speech difficulties, or physical disabilities.
How Serious Is It?
Although it’s rare for travellers to catch Japanese encephalitis, the disease can be very serious. Around 1 in 4 people who develop severe symptoms may die, and many survivors are left with lasting brain damage.
Because there is no specific treatment, prevention is incredibly important.
How to Prevent Japanese Encephalitis?
The best way to prevent Japanese encephalitis is to avoid being bitten by mosquitoes and to consider getting vaccinated. Here are some simple steps you can take:
- Use insect repellent with DEET on exposed skin
- Wear long sleeves and trousers in the evening and at night
- Stay in places with mosquito nets or screens on windows and doors
- Avoid areas with standing water where mosquitoes breed
- Sleep under a mosquito net, especially in rural areas
Japanese Encephalitis Vaccine
If you’re planning to travel to a country where Japanese encephalitis is common, the Japanese encephalitis vaccine is a safe and effective way to protect yourself. It’s especially recommended if:
- You’re staying in high-risk areas for more than a month
- You’ll be spending time in rural areas or rice fields
- You’ll be doing outdoor activities like hiking or camping
- You’re travelling during the rainy season when mosquitoes are more active
Who Should Get the Vaccine?
Not everyone needs the vaccine, but it’s strongly recommended for:
- Long-term travellers to Asia
- People with planned outdoor activities in high-risk regions
- Children over the age of two months (in special cases)
