The resurgence and outbreaks of mumps occur frequently in many countries worldwide in recent years, even in countries with high vaccination coverage. In this study, a descriptive and spatiotemporal clustering analysis at the township level was conducted to explore the dynamic spatiotemporal aggregation and epidemiological characteristics of mumps in Wuhan. During 2005 and 2019, there were 40 685 cases reported in Wuhan, with an average annual morbidity of 28.11 per 100 000 populations. The morbidity showed a fluctuating tendency, and peaked in 2010 and 2018. Bimodal seasonality was found, with a large peak between May and July, and a mild peak from November to January in the following year. Male students aged 5-9-year-old were the main risk group of mumps infection. Significant global spatial auto-correlation was detected except in 2007, 2009 and 2015. The spatial and temporal scan statistics indicated that the hot-spots mainly located at the western and southern areas of Wuhan with variations almost every year. Our findings could assist the public health authorities to develop and improve targeted health strategies, and allocate health resources rationally.
近年来，许多国家，甚至是疫苗接种率较高的国家，都频繁出现腮腺炎的再次暴发和流行。本研究采用描述性和时空聚类分析方法，对武汉市腮腺炎的动态时空聚集性和流行病学特征进行了探讨。2005 年至 2019 年期间，武汉市共报告腮腺炎病例 40685 例，年发病率为 28.11/10 万。发病率呈波动趋势，在 2010 年和 2018 年达到高峰。呈双峰型季节性分布，5-9 岁男学生为腮腺炎感染的主要风险人群。除 2007 年、2009 年和 2015 年外，还检测到显著的全球空间自相关。时空扫描统计分析表明，热点主要位于武汉市的西部和南部地区，且每年都有变化。本研究结果有助于公共卫生部门制定和完善有针对性的卫生策略，合理分配卫生资源。
