[Control of arboviral encephalitis in China (author's transl)]

Japanese B encephalitis is the most important and widespread arbovirus disease in China. Except Tibet and Sinjiang autonomous regions, it occured in every province. JBE virus were isolated from six species of Culex, three species of Aedes, one species of Anopheles and Lasiohelea. The main vector of JBE virus in China is Culex tritaeniorhynchus. The main spreading reservoir host, no doubt, is the pig, but the persistant reservoir is not clear yet. Vaccination of the children under ten years is an efficient measure to control the epidemics of JBE. However, integrated measures will ensure better results. It includes health educational programmes, vaccination, early applying larvicidal insecticides, residual spraying in livestock pens, biological measures against mosquitoes in rice fields.
