摘　　要：目的及时掌握浙江省血吸虫病疫情动态变化，为制定防治策略提供科学依据。方法根据《浙江省血吸虫病监测巩固方案（2007年修订版）》，在全省开展螺情和病情监测。螺情监测用系统抽样结合环境抽查法，查到的钉螺用压碎法检查血吸虫感染情况，用土埋结合药物方法灭螺；病情监测用血清学筛查阳性者粪检，对有螺村和来自尚未控制血吸虫病县人（畜）采用血清学筛查监测病情，血清阳性者进一步粪检。结果在17个流行县（市、区）中查出有螺面积59．62hm2，其中新查出有螺面积0．53hm2；解剖钉螺71450只，未发现感染性钉螺。血清学查病139896人，阳性1279人，阳性率为0．91％；发现输入性血吸虫病病例9例，其中2例急性病例，未发现本地粪检阳性患者（畜）。结论今后要继续加强监测，查清螺情，压缩残存钉螺，防控外来传染源。Objective To investigate the epidemic status of schistosomiasis in Zhejiang province, so as to pro- vide scientific informations for the strategies on schistosomiasis control. Methods The investigation of snail distribution, schistosomiasis monitoring in Zhejiang Province were carried out according to Guidelines for Schistosomiasis Surveillance and Solidification in Zhejiang Prov/nce. The snails were investigated by systematic sampling combined with environmental sampling. Snails were dissected to determine the infection stares and eliminated by ea^-covered method combined drug treatment. Both the persons and livestock, in the villages where the snails inhabited and from the counties where schisto- somiasis was not controlled, were screened by serological methods, and the positive cases were confirmed by fecal exami- nation. Results The residual snails area was 59.62 hm2 in 17 counties, and about 0.53 hm2 newly detected areas were reported. No infective snails was found among 71 450 snails dissected. The serological examination were carried out in 139 896 individuals. There were 1279 persons positive in the detection. The positive rate was 0.91%. No native cases were found except 9 imported cases, including 2 acute cases. Conclusions The control of residual snails and imported cases should be stressed for schistosomiasis control in the future.
