Study Notes
Transmission of Japanese Encephalitis Virus
- Japanese encephalitis virus is transmitted to humans through the bite of an infected mosquito, primarily the Culex tritaeniorhynchus species.
Epidemiology of Japanese Encephalitis
- Human disease of Japanese encephalitis usually peaks during the summer and early fall seasons in temperate areas of Asia.
Vaccine-Preventable Encephalitis
- Japanese encephalitis is the most common vaccine-preventable cause of encephalitis in Asia.
Transmission Cycle of Japanese Encephalitis Virus
- Humans are incidental or dead-end hosts in the transmission cycle of Japanese encephalitis virus.
Classification of Japanese Encephalitis Virus
- The Japanese encephalitis virus belongs to the genus Flavivirus.
Vector of Japanese Encephalitis Virus
- The Culex tritaeniorhynchus mosquito species is primarily responsible for transmitting the Japanese encephalitis virus to humans.
Areas of Japanese Encephalitis Transmission
- The transmission of Japanese encephalitis virus principally occurs in rural agricultural areas, particularly where rice and pigs are found.
Affected Population of Japanese Encephalitis
- In endemic countries, Japanese encephalitis primarily affects children and rural-agricultural workers who live in close proximity to the virus' natural cycle.
