Japanese encephalitis is a viral pathology
of which the vector is the mosquito Culex tritaeniorhynchus. After a period of incubation lasting from one to two weeks, the Japanese encephalitis virus is established and either has no symptoms (in the large majority of cases), or provokes head aches, fever
(up to 106° F), general discomfort, rigidity of the neck, convulsions
and sometimes even coma
. Japanese encephalitis causes death in up to 60% of affirmed cases (mostly children), but the virus cannot be transmitted between humans.
