Japanese encephalitis is an infectious disease caused by this virus (JEV) and is primarily found in rural and tropical areas of East and Southeast Asia. JEV is primarily spread through the bites of infected mosquitoes but can be spread through contact with infected animals as well. Symptoms of the disease vary from mild fever to more serious neurological symptoms and even death. Those most at risk are children and people living in areas with poor sanitation or a lack of adequate mosquito control.

What is Japanese encephalitis?
Japanese encephalitis is an infectious disease caused by the Japanese encephalitis virus. It is primarily spread via the bite of an infected mosquito, although it can also be transmitted through contact with infected pigs or humans. Symptoms of this include fever, headache, vomiting, and seizures, and in some cases, it can cause permanent neurological damage or even death. It is recommended that travelers to areas where the virus is found get vaccinated prior to travel in order to help protect against infection.
Symptoms
The majority of those who get the Japanese encephalitis virus have either no symptoms or mild, transient symptoms that are frequently mistaken for the flu.
However, when the infection advances to the brain, around 1 in every 250 persons who have this experience more severe symptoms.
After infection, this often occurs 5 to 15 days later.
Some symptoms include:
elevated temperature (fever)
seizures (fits)
stiff neck uncertainty
the inability to talk, uncontrolled bodily trembling (tremor)
weakened or paralyzed muscles
Up to one in three individuals who have these more severe symptoms will pass away from the virus.
How common is Japanese encephalitis?
It is extremely uncommon for visitors to risk regions to contract Japanese encephalitis.
Fewer than 1 in a million travellers are thought to contract this each year.
According to estimates from the World Health Organization (WHO), there are around 68,000 cases of Japanese encephalitis per year.
The people who reside and work in rural settings, such as pig farms and rice fields, where the illness is common, are those who are most at risk.
Children under the age of 15 are involved in around 75% of incidents.
Causes of Japanese encephalitis
Japanese encephalitis is an infectious disease caused by the bite of mosquitoes infected with this encephalitis virus. It is a mosquito-borne disease that is most common in rural parts of Southeast Asia, especially in Japan and other parts of East Asia, but it can also occur in other parts of the world. The virus can cause severe neurological symptoms, including seizures, brain damage, and death. In most cases, diagnosis requires laboratory testing, and treatment is limited to supportive care such as administering fluids and preventing secondary infections.
Japanese encephalitis is a viral infection that is spread by mosquitoes. It often affects the central nervous system of the infected person and can lead to serious complications including death or permanent neurological damage. The virus is prevalent in certain areas of Asia and is considered an endemic disease in some countries. The most effective way to prevent this is to take preventive measures such as using insect repellent, wearing long sleeves and pants, and avoiding outdoor activities at night when mosquitoes are more active.
Preventing Japanese encephalitis
The easiest approach to avoid contracting Japanese encephalitis is to get immunized against it before traveling to a region of the world where there is a chance of exposure.
If you want to travel to rural areas, go trekking or camping, the danger is higher.
The vaccination provides a defense against this and is often only made accessible privately.
You should still take actions to lessen your chance of getting bitten by an infected mosquito even if you have received vaccinations, such as:
Use a mosquito net that has been treated with pesticide while sleeping in a room with tight-fitting gauze covering the windows and doors. Cover up with long sleeves, long pants, and socks. Use a high-quality insect repellent on any exposed skin.
Conclusion
Japanese encephalitis is a mosquito-borne viral disease that affects humans, birds, and some mammals. It is caused by the Japanese encephalitis virus (JEV), a member of the flavivirus genus. The disease is most prevalent in Asia and the Far East, but can also be found in other parts of the world. It can cause severe brain damage and even death in some cases.
