How Does Japanese Encephalitis Spread?
JE is a mosquito-borne disease, meaning it spreads through mosquito bites. A mosquito will usually spread the virus to pigs or birds, the virus cannot pass from human-to-human. Human-to-mosquito transmission is rare.
Travellers and residents should take extra precautions in the summer and fall. This time is when spread is most likely.
What Is the Japanese Encephalitis Vaccine?
A Japanese encephalitis vaccination provides the best protection. Two doses given 28 days apart provide a more complete barrier against infection.
The vaccine is considered very safe by the PHAC and other health organizations.

What Are the Symptoms of Japanese Encephalitis?
The majority of JE cases show no symptoms. It can take five to 15 days for symptoms to develop. Travellers may have returned home or is in the middle of a trip when it becomes serious.
Symptoms often start mild with fever, headache or vomiting. Over the next few days, there can be mental or neurological changes. Weakness and movement problems occur. Seizures are common, especially among children.
About 20 to 30 percent of those infected die. Between 30 and 50 percent of survivors have serious mental, neurological or cognitive problems. Paralysis similar to polio can also occur.
There is no treatment for Japanese encephalitis, only supportive care. This means an infected person can be made comfortable, but may not always recover.

Passport Health – Japanese Encephalitis Vaccination
“The lady was very informative. Convinced me of the importance of the Japanese encephalitis vaccine and why I’ll need it.”
“Getting my Japanese encephalitis shot took 5 minutes. Fast and affordable. Thank you!”
“As someone who strongly believes that “knowledge is power” and “safety comes first” I highly recommend going to this clinic and meeting with Passport Health’s staff. They are very professional and informed me of all of the health information I need to know before my trip. I went to visit them last year before going to Taiwan and had a wonderful experience. This year before my trip to Japan I knew for sure I would go back to see her again and I had a great second experience as well. She informed me about Japanese encephalitis and helped me get vaccinated. Very happy to have such a great place to go to prepare and ease my mind before a big trip.”
