摘要:

目的 了解达州市开江县并殖吸虫流行动态、掌握影响因素和评估防治效果,为提高公共卫生水平、制定防治对策和科学研究提供依据。方法 收集2021—2023年达州市开江县并殖吸虫监测资料,查阅开江县2011—2023年并殖吸虫历史监测资料及相关文献,综合监测结果进行对比分析。结果 2021—2023年达州市共调查开江县1 208人,人群血清抗并殖吸虫抗体IgG总阳性率为2.07%(25/1 208),其中,居民抗体阳性率高于学生抗体阳性率。2021—2023年共捕获并解剖溪蟹621只,溪蟹并殖吸虫囊蚴感染阳性率9.66%(60/621),溪蟹平均重量30.20 g,总感染度2.45个/只。与2011—2013年比,2021—2023年人群血清并殖吸虫抗体IgG阳性率、吃生蟹、玩螃蟹或喝生水的比例均明显降低;人群并殖吸虫知晓率明显提高;溪蟹囊蚴感染情况差异无统计学意义。单因素分析结果显示,玩螃蟹和喝生水均是人群血清抗并殖吸虫抗体IgG阳性的危险因素(χ2=6.511、12.922,均P<0.05)。2015—2023年开江县各监测点划分情况为Ⅲ级并殖吸虫疫源地7个,Ⅳ级并殖吸虫疫源地2个。2015—2023年开江县各监测点血清阳性率前3的乡镇为甘棠镇、永兴镇和讲治镇。溪蟹阳性率与采样地海拔高度呈显著正相关(r=0.904,P<0.05)。结论 开江县并殖吸虫自然疫源地存在,人群感染危险因素仍存,需进一步加强并殖吸虫病防治知识的宣传教育工作,改变当地居民不良卫生饮食行为习惯。

Abstract:

Objective To understand the epidemiological dynamics of Paragonimus in Kaijiang County,grasp the influencing factors,and assess the prevention and control effects,so as to provide a basis for improving public health,formulating prevention and control measures and scientific research. Methods From 2021 to 2023,monitoring data of Paragonimus in Kaijiang County were collected,reviewing the historical monitoring data and relevant literature of Paragonimus in Kaijiang County from 2011 to 2023,and synthesizing the monitoring results to make a comparative analysis. Results A total of 1 208 people were surveyed in Kaijiang County from 2021 to 2023,and the total positive rate of human anti-Paragonimus antibody IgG was 2.07%(25/1 208),of which,the positive rate of residents' antibody was higher than that of students' antibody. From 2021 to 2023,a total of 621 freshwater crabs were captured and dissected,with a positive rate of 9.66%(60/621) for Paragonimus metacercaria infection,the average weight of 30.20 g of freshwater crabs,and the total infection level of 2.45 cysticerci/crab. Compared with 2011-2013,the positive rate of human anti-Paragonimus antibody IgG,the proportion of eating freshwater crabs,playing with crabs,and drinking raw water in the population decreased significantly;The knowledge rate of Paragonimus in the population increased significantly;And there was no statistically significant difference in cysticercosis infection of crabs. The results of univariate analysis showed that playing with crabs and drinking raw water were the risk factors for IgG-positive serum anti-Paragonimus antibodies in the population(χ2=6.511,12.922,both P<0.05). The division of monitoring sites in Kaijiang County from 2015 to 2023 was 7 level Ⅲ and 2 level Ⅳ Paragonimus infected sites. The top 3 townships with seropositivity rate of each monitoring site in Kaijiang County from 2015 to 2023 were Gantang Township,Yongxing Township,and Jiangzhi Township. There was a significant positive correlation between the positive rate of crabs and the altitude of the sampling site(r=0.904,P<0.05). Conclusion Kaijiang County is the epidemic foci of paragonimiasis,and the risk factors for population infection still exist,so it is necessary to further strengthen the publicity and education of knowledge of paragonimiasis prevention and control,and to change the bad hygienic and dietary behaviors of the local residents.
