Japanese Encephalitis: Do You Need Protection for Your Trip to Asia or Australia?
If you are planning an adventure to Southeast Asia, the Pacific Islands, or even parts of Northern Australia, you are likely already thinking about malaria or dengue fever. However, there is another mosquito-borne illness that travellers should be aware of: Japanese Encephalitis (JE).
While the risk to the average city-break traveller is low, for those exploring rural areas, trekking, or staying for longer periods, the risk increases. At Staffordshire Travel Care, we provide the JE vaccine and expert risk assessments to keep you safe on your travels.
What is Japanese Encephalitis?
JE is a viral infection spread by the bite of an infected mosquito. It is most common in rural areas, particularly where there are pig farms and rice paddies. While most people who catch it have mild or no symptoms, in rare cases it can cause serious inflammation of the brain (encephalitis), which can be fatal or lead to long-term disability.
Do You Need the Vaccine?
Whether you need the Japanese Encephalitis vaccine depends on several factors that our pharmacists will discuss with you:
- Destination: Is JE endemic in the region you are visiting?
- Duration: Are you staying for a month or longer?
- Activity: Will you be spending a lot of time outdoors, camping, or visiting rural farming communities?
- Seasonality: Risk often increases during the rainy season.
Notably, JE has recently been detected in parts of Northern Australia, making it an important consideration for those planning an outback adventure or visiting rural Queensland or the Northern Territory.
The Vaccination Course
The vaccine is usually given as two doses, with the second dose 28 days after the first. For those aged 18-65, an accelerated schedule is sometimes possible. Because the course takes time, we recommend visiting our Staffordshire clinics (located in Stoke, Stafford, and beyond) at least six weeks before you fly.
Pharmacist’s Note
"Japanese Encephalitis is rare for travellers, but the consequences can be severe. Because the mosquitoes that carry JE are most active at night, I always advise 'double-up' protection: get vaccinated if your risk is high, and always use a high-quality DEET-based repellent and sleep under a mosquito net if you are in a rural area."
