摘要
广东省于１９８５年消灭血吸虫病，１９８６～１９９５年开展监测巩固工作。１０年来，用各种方法查螺９７７６８４８８ｍ２，１９９２年仅在径口华侨农场曹寨村发现１残存螺点２０００ｍ２，钉螺最高密度为１２只／０．１１ｍ２，自然感染率为２．２９％（２１／９１８）。共复查历史病人５５１４３人，其中１例粪检血吸虫卵阳性，复治１５０２５人（２７．２５％）。新感染调查易感人群，皮试阳性率５．６１％（２９４９／５２５７５），粪检血吸虫卵阳性者２人（１９９２年曹寨村）。解剖野鼠１１６３０只，未发现血吸虫卵。大量监测结果显示，广东省消灭血吸虫病后，虽于１９９２年在曹寨村出现１个疫点，但经及时处理迅速扑灭，而其它地区均未发现残存钉螺及新感染病人，认为其消灭血吸虫病的成果巩固。
Schistosomiasis surveillance in Guangdong was carried out by checking the residual snails,detecting the residual patients and new infections. The imported infection sources were also detected. Altogeter 97 768 488 m 2 in the previous endemic areas were checked for 10 years (1986-1995). One focus of residual snails was found(1992). The total area of residual snail focus was 2 000 m 2 with a positive rate of 2.29%(21/918). A population of 55 143 with infection histories were detected and 15 025 of them were retreated. A susceptible population of 52 575 were tested by skin test with a positive rate of 5.61%. Two of them were found positive by stool examination (in the area of residual snail focus). A total of 54 204 young cattle were also tested by stool examination,but all of them were negative. A total of 11 630 wild mice were dissected,no schistosome or its egg was found. The results indicated that the surveillance measures of schistosomiasis in Guangdong were effective and successful.
