Japanese Encephalitis : ‘ The leading cause of viral encephalitis in Asia’

Japanese encephalitis (JE) is a mosquito-borne viral infection of the brain. It is the leading cause of viral encephalitis in Asia. The virus appears to have originated from its ancestral virus in the mid-1500s in the Indonesia-Malaysia region and evolved there into different genotypes later.


It is usually observed that most people infected with it either have no symptoms or have mild, short-lived symptoms, which are often mistaken as flu.

One can see the symptoms only once the infection reaches the brain. Some of the symptoms are as follows :-

1. Seizures

2. High fever

3. Stiff neck

4. Mental behavioural changes

5. Muscle weakness


Japanese encephalitis is caused by a flavivirus, which can affect both humans and animals. The virus is passed from animals to humans through the bite of an infected mosquito. If you get bitten by an infected mosquito, it can pass on the virus.

The mosquitoes that carry Japanese encephalitis particularly breed in areas which have flooded rice fields or marshes, which is usually in rural areas, although infected mosquitoes have also been found in urban areas. They usually feed between sunset and sunrise.



1. Avoid Mosquito bites

One of the best ways to prevent Japanese encephalitis is to avoid getting bit by mosquitoes and by controlling the mosquito around you using repellents, as the insects are the main vector for the disease.

2. Wear protective clothing

It is always advisable to wear clothing which covers your entire arms and body. If you are heading out, cover your legs by wearing long-pants along with socks and shoes. Also, it is better if you use mosquito-repellent like Good knight roll-on. It comes in two variants – bubblegum fragrance and citrus fragrance which offers 8 hours of protection.

3. Get vaccinated

For people who love travelling or tend to spend most of their time travelling to different places, one of the best ways of prevention is to get vaccinated from JE. The World Health Organisation (WHO) states that getting vaccinated is the one of the best and the safest methods of preventing the disease.

With the correct recognition of symptoms and use of proactive measure to prevent it, Japanese Encephalitis can be successfully avoided.
