囊虫病在中国仍然是一个公共卫生问题，疾病的流行归因于社会经济和公共卫生条件差。在中国开展全国寄生虫病普查后，这一食源性寄生虫病被列为有效控制的优先事项。为更好地了解云南省大理州囊虫病发病趋势，通过评估2000 - 2014年囊虫病时空分布特征，对大理州囊虫病的分布进行预测。囊虫病病例数据库由大理州血吸虫病防治研究所临床科提供。通过描述脑囊虫病的流行病学特征，运用作图法、扫描法和空间自相关分析法分析脑囊虫病病例的时空分布，共发现脑囊虫病患者3,347例。青壮年男性农民囊虫病患病率最高，白族也是囊虫病的高发人群。2000-2014年期间确定了三个聚合领域。2000年至2007年，热点分析涉及大理市、洱源县和漾濞县，区域逐渐向该省西部和北方转移。热点图显示洱源县囊虫病是一个长期存在的问题。结果表明，大理地区存在3个囊虫病聚集群，其发病原因与环境因素和不良生活方式有关。因此，建议在这些地区采取多部门控制措施，以有效控制和预防人群中的囊虫病。
Cysticercosis remains a public health problem in China, with disease prevalence attributed to poor socio-economic and public health conditions. This parasitic food-borne disease was prioritized for effective control following implementation of the national surveys on parasitic diseases carried out in China. We predicted the cysticercosis distribution in Dali, Yunnan Province by assessing spatio-temporal distribution characteristics between 2000 and 2014 to better understand the trend of the disease incidence. A database of cysticercosis cases was provided by the clinical department at the Dali Prefectural Institute of Research and Control of Schistosomiasis. Describing the epidemiological features of cysticercosis and analyzing its spatiotemporal distribution of cases using mapping, scanning and spatial autocorrelation analysis, our findings found a total of 3,347 patients with cysticercosis infection, neurocysticercosis in particular. Cysticercosis prevalence was the highest among young and middle-aged male farmers, and also predominant among the Bai nationality. Three aggregation areas were identified during the period 2000-2014. Hotspot analysis implicated Dali City, Eryuan County and Yangbi County between 2000 and 2007, with areas gradually shifting towards the western and northern parts of the province. The hotspot map indicated that Eryuan County was a constant problem with respect to cysticercosis. The results indicated three cysticercosis clusters in Dali that could be attributed to environmental factors and unhealthy lifestyles. Multi-sectoral control initiatives are, therefore, recommended in these areas to effectively control and prevent cysticercosis among the population.
