A common form of arbovirus encephalitis in south and east Asia, an acute inflammatory viral infection, caused by a flavivirus, transmitted by Culex mosquitoes. It is prevented by vector control and elimination or exclusion of mosquitoes from contact with human hosts. Epidemics were formerly common during wet seasons of high mosquito prevalence. A vaccine developed in Japan is used to protect children and is recommended for those planning extended visits to endemic rural regions.
