JAPANESE ENCEPHALITIS: Symptoms And Preventions



We all know that Japanese encephalitis is one of the most dangerous and life-threatening diseases. Does anyone know who causes this disease and what are its symptoms ad preventive measures? If no then please go through the below as I am going to discuss “JAPANESE ENCEPHALITIS: Symptoms And Preventions” in the below-mentioned context.


Japanese encephalitis is a virus that belongs to the Flavivirus family. It is passed on to others by a mosquito named Culex. This virus can infect horses and pigs as well as humans too. This virus can cause encephalitis in horses and leads to miscarriages in pigs. The source of this virus is a host and a vector helps in passing it on. Wild birds are considered to be the natural host of this virus and mosquitoes are the vectors of this virus. But a vector doesn’t cause disease but it only passes it on to others. When mosquitoes infect one animal with that virus, then the animal becomes a carrier of that virus. And when another mosquito feeds on these animals who have newly acquired the virus, they take it on board and infect other animals. People who are living in rural areas are always at a higher risk of getting acquired by this virus because this virus is common there. Japanese encephalitis is also common in towns and cities.


A person infected with Japanese encephalitis has no symptoms at all but if he/she has any symptoms then it will appear only after 5-15 days duration from the time it has infected. A person with mild Japanese encephalitis would face symptoms like fever and headache but for people in more severe cases, more serious or dangerous symptoms can occur quickly.

Symptoms are given below:-

  • High fever
  • Vomiting
  • Headache
  • Tremors
  • Spastic paralysis
  • Nausea


The best way with the help of which one can prevent the risk of suffering from Japanese encephalitis is vaccination and insect repellent.

  1. Vaccination:- A effective and efficient vaccine is available to prevent from getting this virus. A doctor will give you this vaccine in the form of an injection over two doses. The second dose is given only after 28 days of the first dose. An accelerated schedule is also possible in which one can take the second dose just after 7 days of the first dose. But the accelerated schedule is safe and effective for only those people whose ages are between 18 and 65 years.
  2. Insect repellent:– People who spend most of the time outdoors in rural should wear protective clothing and should sleep in air-conditioned rooms. People who are travelers and come to live in a place where Japanese encephalitis is common are vulnerable to get infected than those who lived in that area permanently for many years.


From the above, we can conclude that It is one of the most dangerous diseases and therefore people should always try to prevent it by taking preventive measures and should immediately consult a doctor if he/she has that disease.
