Japanese encephalitis/ Japanese B encephalitis
- The Japanese encephalitis virus is a virus from the family Flaviviridae.
- Domestic pigs and wild birds (herons) are reservoirs of the virus; transmission to humans may cause severe symptoms.
- One of the most important vectors of this disease is the mosquito Culex tritaeniorhynchus.
- This disease is most prevalent in Southeast Asia and the Far East.
- Japanese encephalitis has an incubation period of 5 to 15 days and the vast majority of infections are asymptomatic Only 1 in 250 infections develop into encephalitis.
