What is Japanese Encephalitis and how does it spread?

Japanese Encephalitis is a viral brain infection caused by JE virus. JE is closely related to West Nile encephalitis, dengue, and yellow fever.

Mosquitoes, particularly the Culex Tritaeniorhynchus mosquito, pick up the virus from feeding on infected birds and pigs. Infected mosquitoes can then transmit the virus to humans through their bites.1,2

The disease has a long history, with the first clinical case of Japanese Encephalitis being documented in Japan in 1871.3 Despite this fact, there is no specific treatment for it to date.1

Recognizing the symptoms

Most human infections are asymptomatic or result in only mild symptoms.1,2,3

However, 1 out of 250 infections will rapidly progress into severe complications such as inflammation of the brain (encephalitis)1,2,3.

Symptoms typically develop 5 to 15 days after the bite of an infected mosquito and include2,3:
