The occurrence of childhood encephalitis was evaluated in a population-based study in an area with no arboviral infections. Ninety-five children were treated for encephalitis during 1973 to 1987, giving an annual incidence of 8.8/100,000 children younger than 16 years of age (95% confidence interval, 6.7 to 10.1). Based on virologic and serologic studies the most common etiologic agents were varicella (24 cases), mumps (8), herpes simplex (7) and measles (4). The etiology remained unknown in 37 children. No cases of encephalitis caused by mumps, measles or rubella were found in the population after 1982, when vaccination against these viruses was introduced.
在一个没有虫媒病毒感染的地区，通过一项基于人群的研究对儿童脑炎的发病情况进行了评估。1973年至1987年期间，有95名儿童接受了脑炎治疗，16岁以下儿童的年发病率为8.8/10万（95%置信区间为6.7至10.1）。根据病毒学和血清学研究，最常见的病原体是水痘（24例）、腮腺炎（8例）、单纯疱疹（7例）和麻疹（4例）。37名儿童的病因仍不清楚。1982年引入针对这些病毒的疫苗接种后，该人群中未发现由腮腺炎、麻疹或风疹引起的脑炎病例。
