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.
包虫病在中国仍是一个公共卫生问题，其发病率归因于较差的社会经济和公共卫生条件。在实施全国寄生虫病调查后，这种食源性寄生虫病被优先列为有效控制的对象。我们通过评估 2000 年至 2014 年之间的时空分布特征，预测了云南省大理市的包虫病分布情况，以便更好地了解疾病发病率的趋势。大理州寄生虫病防治研究所的临床部门提供了包虫病病例数据库。通过绘图、扫描和空间自相关分析描述包虫病的流行病学特征，并分析其病例的时空分布，我们发现共有 3347 例囊虫病感染患者，特别是神经囊虫病。囊虫病的流行率在年轻和中年男性农民中最高，而且在白族中也很普遍。在 2000 年至 2014 年期间，确定了三个聚集区。热点分析表明，2000 年至 2007 年期间，大理市、洱源县和漾濞县是热点地区，这些地区逐渐向该省的西部和北部转移。热点图表明，洱源县一直是包虫病的问题地区。结果表明，大理有三个包虫病群集，这可能归因于环境因素和不健康的生活方式。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包虫病。
