One of such disease that one can contract while on a trip is Japanese encephalitis, that is common in many countries of Asia.

What is Japanese encephalitis?

Japanese encephalitis is a very serious viral disease that is caused by a virus that belongs to the same genus as yellow fever, dengue and West Nile virus, and is a mosquito-borne flavivirus.

Mode of transmission

Japanese encephalitis virus is transmitted to humans from infected mosquitoes of the culex species. The disease is prevalent in rural areas of close proximity between humans and the host.

Transmission is mostly during the warm period. This disease is mainly found in Japan, hence the name. However, it has extended beyond Japan and can even be found in places like Australia.

About one-third of people who are infected do not experience symptoms, another third die while the remaining percentage suffer long term neurological problems. The symptoms that some people experience are;

  • Fever
  • Headache
  • Gastrointestinal pain (in children)
  • Vomiting
  • Inflammation of the brain
  • Disorientation
  • Coma
  • Seizure and
  • Death

As the name implies, one will generally assume that it is found only in Japan. However, Japanese encephalitis occurs in South East Asia, Australia and of course, Japan. The thing to note is that the Japanese encephalitis virus is found mostly in areas where mosquitoes breed.

Japanese encephalitis vaccinations

With the fact that there is no cure for Japanese encephalitis, it is therefore important to get vaccinated against the virus, especially if you find yourself in such areas or plan to make a trip to such areas. Vaccination against Japanese encephalitis involves a drug named Ixiario. It is injected in two doses, into the deltoid muscle of the arm. The second injection is administered 27 days after the first dose, on the 28th day.

After vaccination, you will still need regular boosters every 1-2 years, in order to protect you from contracting the nasty disease.

Anyone can get vaccinated against the Japanese encephalitis. It is been discovered that Japanese encephalitis is mostly common in children. Because of this, the vaccine is open to be used by anyone including children.

Side effects

Although rare, but there have been some reports of side effects of the vaccine. It is usually mild and can include pain, inflammation, flu-like symptoms and even redness of the injected area. In very rare cases, there have been reports of migraines or vertigo.

How long will the vaccine last?

The duration of the protection period of the vaccines cannot be said for sure. No one really knows how long the protection will last. However, if the person is at a risk area, aged 17 and above, a booster might be recommended especially if the vaccine was administered over a year earlier.
