A simple dusk index was developed to monitor the density of recognized vectors of Japanese encephalitis virus (JEV) based on hand catches around cattlesheds at dusk and parous rates. When used routinely in combination with sentinel animal studies for surveillance in villages with a high prevalence (46.2%) of neutralizing antibodies against JEV in children under 16 years, there was a peak in vector density and virus activity during the north-east monsoon period, October-December. The reasons for an unusual outbreak of cases of encephalitis during the summer months of 1984 are discussed.
基于黄昏时分在牛棚周围的人工捕捉以及孕蚊率，开发了一种简单的黄昏指数来监测日本脑炎病毒（JEV）公认病媒的密度。当与哨兵动物研究常规联合使用，用于对16岁以下儿童中抗JEV中和抗体患病率较高（46.2%）的村庄进行监测时，在10月至12月的东北季风期病媒密度和病毒活性出现高峰。本文讨论了1984年夏季脑炎病例异常爆发的原因。
