Abstract：
An outbreak of Japanese encephalitis (JE) was reported in Solan district of Himachal Pradesh, India in May 2018 wherein a total of eight JE cases were reported by the state health department, of which seven cases were confirmed by ELISA. An entomological survey was carried out to investigate the presence of vector mosquitoes in the affected area. Field visits were undertaken in eight villages of two blocks in Solan district. Larval collections were made from the major aquatic sites and emerging mosquito species were identified. Seepage water ditches were the main source of JE vector mosquitoes Culex tritaeniorhynchus and Cx. bitaeniorhynchus. During hand catch collections of adult mosquitoes, three vector species of JE,Culex tritaeniorhynchus (Man Hour Density 1-14), Cx. vishnui (MHD 2) and Cx. bitaeniorhynchus (MHD 1-2) were collected. A few specimens of Cx. tritaeniorhynchus (6 no.) were also collected in light trap collections. Since this was the first reported outbreak of JE from Himachal Pradesh, India, studies on sero-surveillance in addition to bionomics of JE vectors are required for better understanding of epidemiology of JE in Himachal Pradesh. Moreover, there is a need to study the role of climate change especially rising temperature in the context of JE in Himachal Pradesh.
摘要：
据报道，在喜马al尔邦的索兰地区爆发了日本脑炎（JE），印度2018年5月，州卫生部门共报告了8例JE病例，其中7例经酶联免疫吸附试验证实。进行了昆虫学调查，以调查受影响地区媒介蚊子的存在。在索兰区两个街区的八个村庄进行了实地访问。从主要的水生地点收集幼虫，并确定了新兴的蚊子。渗水水沟是JE媒介蚊子三带囊库蚊和Cx的主要来源。bitaeniorhynchus.在手抓成年蚊子的过程中，JE的三个媒介物种，三带库蚊（人小时密度1-14），Cx.vishnui（MHD2）和Cx。收集了双环鱼（MHD1-2）。Cx的一些标本。tritaeniorhynchus（6号)也被收集在光阱集合中。由于这是喜马al尔邦首次报告的JE爆发，印度,为了更好地了解喜马al尔邦JE的流行病学，需要进行除JE媒介生物学外的血清监测研究。此外，在喜马al尔邦的JE背景下，有必要研究气候变化尤其是气温上升的作用。
