摘　　要：为了解广西壮族自治区(简称广西)灵山县人群华支睾吸虫感染情况,2016—2019年在灵山县东、西、南、北、中等5个片区各随机抽取1个乡(镇)的1个行政村开展调查,每个行政村整群抽样法抽取≥3岁的常住居民200人。每年共调查1000人以上,往年已参加过调查的人不再纳入。采集调查对象粪样,用改良加藤厚涂片法(Kato-Katz法,一粪二检)检查华支睾吸虫虫卵并计数。结果显示,2016—2019年灵山县共调查4363人,华支睾吸虫总感染率为4.86%(212/4363),以轻度感染为主,占总感染数的93.87%(199/212),无重度感染者。2016—2019年感染率分别为3.59%(42/1170)、5.03%(51/1014)、7.58%(79/1042)和3.52%(40/1137),不同年度间感染率差异有统计学意义(χ^(2)=25.271,P<0.01)。5个调查点中,感染率最高的为烟墩镇长麓村(13.12%,124/945),最低的为那隆镇陈垌村(0.37%,3/821),不同调查点人群感染率间差异有统计学意义(χ^(2)=211.912,P<0.01)。男性感染率为7.43%(167/2248),高于女性的2.13%(45/2115)(χ^(2)=66.244,P<0.01);50~59岁年龄组感染率最高(10.4%,62/596),各年龄组感染率差异有统计学意义(χ^(2)=142.690,P<0.01);教师及其他职业感染率最高(9.33%,7/75),不同职业中人群感染率差异有统计学意义(χ^(2)=81.314,P<0.01);大专及以上文化水平人群感染率最高(8.00%,2/25),不同文化水平人群间感染率差异有统计学意义(χ^(2)=40.237,P<0.01)。2016—2019年广西灵山县华支睾吸虫感染处于中度流行水平,各乡(镇)的感染率存在差异。To understand the prevalence of Clonorchis sinensis infection in Lingshan County,one town/village was randomly selected from each of the eastern,western,southern,northern and central administrative regions for investigation from 2016 to 2019.By cluster sampling,200 permanent residents aged more than 3 years were selected from each study site.More than 1000 people were surveyed each year with no duplicate enrollment.The fecal samples were collected,and processed using the modified Kato-Katz method(two examinations per sample)for egg counts.Among 4363 participants,4.86%(212/4363)were infected with C.sinensisand the majority were mild infections,accounting for 93.87%(199/212)of the total infections with no severe infection case.The infection rates from 2016 to 2019 were 3.59%(42/1170),5.03%(51/1014),7.58%(79/1042)and 3.52%(40/1137),respectively.The difference between years was statistically significant(χ^(2)=25.271,P<0.01).Among the five survey sites,the highest infection rate was found in Changlu Village,Yandun Town(13.12%,124/945),and the lowest was found in Chentong Village,Nalong Town(0.37%,3/821).The difference between study sites was statistically significant(χ^(2)=211.912,P<0.01).The infection rate in males was 7.43%(167/2248),which was significantly higher than that in females(2.13%,45/2115)(χ^(2)=66.244,P<0.01).The 50-59 age group had the highest infection rate(10.4%,62/596)and the differences between age groups were significant(χ^(2)=142.690,P<0.01).The infection rate of teachers and other occupations was the highest(9.33%,7/75),and the differences between occupations were significant(χ^(2)=81.314,P<0.01).The highest infection rate found in those with college or higher education levels(8.00%,2/25),and significant difference in people with different education levels(χ^(2)=40.237,P<0.01).From 2016 to 2019,the prevalence of C.sinensis in Lingshan County was moderate and different for each town/village.
