Signs and Symptoms of Japanese Encephalitis

If you have been travelling to rural areas of Southeast Asia, the Far East, or Pacific Islands, you should be aware of the prevalence of Japanese Encephalitis. While it may be uncommon for travellers to acquire it, it is one of the most common viral brain infections found in pigs and birds located in these areas. The infection is passed on to mosquitoes, so you should use preventive measures to fend them off their bites.

One thing you should know about Japanese Encephalitis is that there is no available cure as of today. It is for this reason that one in three people who become infected can potentially die. Hence, the best option you have at combating the infection is by receiving our Japanese Encephalitis Vaccine. It would be best to learn more about the symptoms of this disease to make yourself more aware. 

Usual Symptoms of the Infection
You should know that a person who has this viral brain infection will usually have no symptoms or present with mild, short-lived symptoms, that can easily be dismissed as flu. At least 1 in every 250 people who become infected will develop more serious symptoms of the viral infection which eventually reaches the brain. Severe symptoms usually show up 5 to 15 days later after the initial transmission and can include: 

  • High body temperature
  • Stiff neck
  • Seizure
  • Incapable of speech
  • Severe confusion 
  • Body tremors
  • Paralysis or muscle weakness

In some cases, those who survive the deadly infection’s symptoms will gradually improve. However, the symptoms will take several months to dissipate until the infection is eliminated, and some will be left with indefinite brain damage. Those with permanent brain damage will experience life-long issues, including muscle twitches, paralysis, tremors, personality disorder, muscle weakness, and learning difficulties.

How to Prevent Getting Infected
It is rare for travellers to become infected with Japanese Encephalitis, however it is still best to learn how to avoid any possible transmission. The most effective method of fighting the infection is to stay away from rice fields and pig farms, especially if they are damp areas. The infection is passed on to people via mosquitoes, so protecting yourself adequately from receiving mosquito bites is paramount when travelling in high risk areas.

Get Vaccinated
Fortunately, a vaccination is available, and you can receive your Japanese Encephalitis injection at our clinic to avoid infection. Do not rely on insect repellent alone because insect repellent is not always 100% effective. The best way to ensure you can avoid any complications from Japanese Encephalitis is to vaccinate yourself before you travel.
