To understand the prevalence and epidemiological features of clonorchiasis sinensis based on inpatients in Zhongshan City. All of the 23 town hospitals in Zhongshan City were selected as the surveillance hospitals in 2016. Among the inpatients from those hospitals, those lived in the city longer than 6 months were selected as the surveillance subjects. The stool specimens of the subjects were collected and examined by the modified Kato-Katz thick smear method for the eggs of . The crude infection rates of of the subjects were standardized according to the age and sex compositions of the population in Zhongshan City, 2016. Meanwhile, the infection rates of the subjects from different towns and those combined with related clinical diseases were analyzed. A total of 2 667 people were included in the surveillance, among which 219 were tested as positives, with a crude infection rate of 8.21%. For the positives, the male accounted for 81.74% (179/219), and their age ranged from 4 to 89 years with the mean value of (62.20±13.80) years. After standardization by age and sex composition, the infection rate was 3.62% for the whole population, the rates of the male and the female were 5.46% and 1.53%, respectively, and the former was 3.57 times as high as the latter. Both the infection rates of the male and the female rose as the age increasing ( = 99.91, = 16.51, both < 0.01). The standardized infection rates among the subjects in different towns ranged from 0 to 10.40%, and the rates in the north towns were higher than those in the south towns. The standardized rate was 9.22% for the subjects combined with gallstone, 3.40% for those not combined with gallstone, and the former was 2.71 times as high as that of the latter. The people aged 30 years and above, with gallstone or living in towns with high infection rates are the key population for prevention and control of clonorchiasis in Zhongshan City.
了解基于中山市住院患者的华支睾吸虫病的流行情况和流行病学特征。2016年，中山市全部23家镇医院被选为监测医院。在这些医院的住院患者中，选取在该市居住超过6个月的患者作为监测对象。收集监测对象的粪便标本，采用改良加藤厚涂片法检测华支睾吸虫卵。根据2016年中山市人口的年龄和性别构成，对监测对象的粗感染率进行标准化。同时，分析不同镇的监测对象以及合并相关临床疾病的监测对象的感染率。共2667人纳入监测，其中219人检测为阳性，粗感染率为8.21%。阳性者中，男性占81.74%（179/219），年龄4至89岁，平均（62.20±13.80）岁。经年龄和性别构成标准化后，全市感染率为3.62%，男性和女性感染率分别为5.46%和1.53%，前者是后者的3.57倍。男性和女性感染率均随年龄增长而上升（χ² = 99.91，P = 16.51，均P < 0.01）。不同镇监测对象的标准化感染率在0至10.40%之间，北部镇的感染率高于南部镇。合并胆结石的监测对象标准化率为9.22%，未合并胆结石的为3.40%，前者是后者的2.71倍。30岁及以上、患有胆结石或居住在华支睾吸虫感染率高的镇的人群是中山市华支睾吸虫病防控的重点人群。
