Japanese Encephalitis (JE), the brain fever disease, is a viral
disease which infects about 30,000-40,000 people annually the world
over. This statistic could be possibly higher considering the secondary
form of this disease leads to a milder case of JE which is usually not
reported.
JE is a water borne disease that is prevalent in Asia, specially South East Asia, China, Philippines and Cambodia. JE is transmitted by mosquitoes belonging to the Culex tritaeniorhynchus and Culex vishnui groups, which breed particularly in flooded rice fields. The virus circulates in birds LIKE herons and egrets and is amplified in pigs which are the amplifying hosts as in here the virus reproduces and is transmitted to the mosquitoes. The virus tends to spill over into human populations when infected mosquito populations build up explosively and the human biting rate increases.
The primary form of this disease has no cure and leads to head aches, neck stiffness, disorientation, coma, seizures , spastic paralysis and death. So far no cure for this disease has been found and vaccination remains the only prevention. The treatment so far depends on relieving the symptomatic problems particularly pain and the cranial pressure.
