目的掌握湖北省国家级监测点血吸虫病疫情情况,为制定血吸虫病防治对策提供科学依据。方法按《全国血吸虫病监测方案(2011年修订版)》的要求,开展16个监测点的监测工作,并将两年的监测结果进行比较。结果湖北省2012年16个国家监测点居民感染率为0.42%,与2011年的0.40%相比变化不大;耕牛感染率分别为0.81%和0.58%,与2011年相比下降了28.39%;活螺平均密度分别为0.186 5只/0.11 m2、0.196只/0.11 m2,2011年感染螺平均密度为0.000 04只/0.11 m2,钉螺感染率为0.022%。2012年16个监测点均未发现感染性钉螺。结论监测点人畜感染率呈现持续下降,但疫情仍不稳定,有反弹的可能,因此,应进一步加强传染源控制措施以及查灭螺力度,防止疫情反弹。
Objective To master the epidemic situation of schistosomiasis at the national level in Hubei Province and provide a scientific basis for the development of schistosomiasis control strategies. Methods According to the requirements of National Schistosomiasis Surveillance Program (Revised in 2011), 16 monitoring sites were monitored and the two-year monitoring results were compared. Results In 2012, the infection rate of residents in 16 national monitoring sites in Hubei Province was 0.42%, which was not significantly different from 0.40% in 2011. Cattle infection rates were 0.81% and 0.58% respectively, down 28.39% from 2011, ; Average density of live snails were 0.186 5 /0.11 m2,0.196 /0.11 m2 respectively, and in 2011, the average intercellular density was 0.000 04 /0.11 m2, and the infection rate of snails was 0.022%. Infectious snails were not found in all 16 monitoring sites in 2012. Conclusions The infection rate of human and animal in the monitoring sites shows a continuous decline, but the epidemic is still unstable and there is a possibility of rebound. Therefore, we should further strengthen the control measures of infection sources and check the strength of spikes to prevent the epidemic from rebounding.
