Japanese encephalitis (JE) is an infection of the brain caused by the Japanese encephalitis virus (JEV). [3] While most infections result in little or no symptoms, occasional inflammation of the brain occurs. [3] In these cases, symptoms may include headache, vomiting, fever, confusion and seizures. [1] This occurs about 5 to 15 days after ...
Japanese encephalitis vaccines first became available in the 1930s. [3] One of them was an inactivated mouse brain-derived vaccine (the Nakayama and/or Beijing-1 strain), made by BIKEN and marketed by Sanofi Pasteur as JE-VAX, until production ceased in 2005. The other was an inactivated vaccine cultivated on primary hamster kidney cells (the ...

Prognosis is good for most individuals who are infected by an encephalitic virus but is poor among those who develop severe symptoms, including viral encephalitis. Long-term complications of viral encephalitis typically relate to neurological damage, such as experiencing seizures, memory loss, and intellectual impairment.
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [ 2 ] The word is from Ancient Greek ἐγκέφαλος , enképhalos 'brain', [ 37 ] composed of ἐν , en , 'in' and κεφαλή , kephalé , 'head', and the medical suffix -itis 'inflammation'.
The Culex vishnui Theobald mosquito species belongs to a sub-type that also includes two other carriers of the Japanese encephalitis virus - Culex tritaeniorhynchus Giles and Culex pseudovishnui Colless. [11]
Eastern equine encephalitis (EEE) and Western equine encephalitis (WEE) occur in the United States where they cause disease in humans, horses, and some bird species. Because of the high mortality rate, EEE and WEE are regarded as two of the most serious mosquito-borne diseases in the United States.
The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles.
