In India, quality surveillance for acute encephalitis syndrome (AES), including laboratory testing, is necessary for understanding the epidemiology and etiology of AES, planning interventions, and developing policy. We reviewed AES surveillance data for January 2011-June 2012 from Kushinagar District, Uttar Pradesh, India. Data were cleaned, incidence was determined, and demographic characteristics of cases and data quality were analyzed. A total of 812 AES case records were identified, of which 23% had illogical entries. AES incidence was highest among boys<6 years of age, and cases peaked during monsoon season. Records for laboratory results (available for Japanese encephalitis but not AES) and vaccination history were largely incomplete, so inferences about the epidemiology and etiology of AES could not be made. The low-quality AES/Japanese encephalitis surveillance data in this area provide little evidence to support development of prevention and control measures, estimate the effect of interventions, and avoid the waste of public health resources.
在印度，急性脑炎综合征（AES）的质量监测，包括实验室检测，对于了解 AES 的流行病学和病因学、规划干预措施和制定政策是必要的。我们回顾了印度北方邦库什纳加尔区 2011 年 1 月至 2012 年 6 月的 AES 监测数据。对数据进行了清理，确定了发病率，并对病例的人口统计学特征和数据质量进行了分析。共确定了 812 份 AES 病例记录，其中 23%的记录存在不合理的条目。AES 发病率在 6 岁以下男孩中最高，且病例在季风季节达到高峰。实验室结果记录（日本脑炎可用，但 AES 不可用）和疫苗接种史记录大多不完整，因此无法对 AES 的流行病学和病因学做出推断。该地区 AES/日本脑炎监测数据质量低，几乎没有证据支持制定预防和控制措施、评估干预措施的效果，以及避免公共卫生资源的浪费。
