摘要
目的了解2010-2011年南京市栖霞区南中村国家血吸虫病监测点疫情动态,为评价防治效果和制订防治策略提供科学依据。方法按照《全国血吸虫病监测方案》要求,每年开展螺情、病情监测。结果 2011年南中村监测点活螺框出现率和活螺平均密度较2010年分别下降11.67%和95.49%,连续2年未发现感染性钉螺。常住居民血吸虫感染率从2010年的9.93%(95/957)下降为2011年的1.35%(7/519),未发现急性血吸虫感染和晚期血吸虫病患者,亦未发现粪检阳性家畜。结论南中村国家血吸虫病监测点血吸虫病疫情呈逐年下降趋势,所采取的常规综合防治措施积极有效,但有螺面积未见明显有效压缩,仍处于不稳定状态。提示今后要强化灭螺措施,并确保灭螺质量;同时要积极开展江滩有螺环境治理,继续开展螺情和血吸虫病传染源监测,以防止血吸虫病疫情反复。
Objective To understand the dynamic of schistosomiasis epidemic situation in a national surveillance site, Nanzhong Village, Qixia District, Nanjing City, 2010-2011, so as to provide the evidence for evaluating the control effect and formulating prevention countermeasures. Methods According to the National Schistosomiasis Monitoring Program, the Oncomelania snail status and the situation of endemic schistosomiasis were surveyed and the data were analyzed statistically. Results The emergence rate of frames with living Oncomelania snails decreased by 11.67% and the average density of living snails decreased by 95.49% in 2011 compared to those in 2010. No infected snail was found during the past 2 years. The infection rate of schistosome in the permernant residents decreased from 9.93% （95/957） in 2010 to 1.35% （7/519） in 2011, and no acute schistosomiasis case was found. All the stool tests of schistosome infection in domestic animals were negative. Conclusions The schistosomiasis epidemic situation shows a decline trend year by year which demonstrates the routine comprehensive control measures are effective. However, the snail habitat area has not decreased significantly. Therefore, we should strengthen the snail control and continue the surveillance of snail status and infectious sources of schistosomiasis
