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1 000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4 363人,华支睾吸虫总感染率为4.86%(212/4 363),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%(42/1 170)、5.03%(51/1 014)、7.58%(79/1 042)和3.52%(40/1 137),不同年度间感染率差异有统计学意义(χ2 = 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(χ2 = 211.912,P < 0.01)。男性感染率为7.43%(167/2 248),高于女性的2.13%(45/2 115)(χ2 = 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(χ2 = 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(χ2 = 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(χ2 = 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。

Abstract:

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 1 000 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 4 363 participants, 4.86% (212/4 363) 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% (42/1 170), 5.03% (51/1 014), 7.58% (79/1 042) and 3.52% (40/1 137), respectively. The difference between years was statistically significant (χ2 = 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 (χ2 = 211.912, P < 0.01). The infection rate in males was 7.43% (167/2 248), which was significantly higher than that in females (2.13%, 45/2 115) (χ2 = 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 (χ2 = 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 (χ2 = 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 (χ2 = 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.
