摘要
本文报告了湖南省洞庭湖一个洲岛型血吸虫病流行区1996年居民病情调查结果。该洲岛由大（青山Qingshan）、小（严家山Yanjiashan）二岛所组成。共检查居民1909人，受检率为72．2％，Kato－Katz法阳性率大岛为14．6％；小岛为23．7％。大岛血吸虫感染有两个高峰年龄组（25岁—35岁和45岁—55岁）；小岛年龄组感染高峰略有后移。感染者人群感染度（EPG）轻、中、重分别为71．1％、21．3％和76％。肝、脾肿大率分别为21．9％和1．3％。感染率与人群感染度无直接相关；重感染度人群的肝肿大率及腹泻率高于其它组；渔民血吸虫感染率最高（22．4％）；学生的感染度最重（EPG220）。结果表明：该地目前所采用的选择性人群化疗的防治措施未能达到理想的防治效果，宜进一步加强综合防治力度。
The prevalence and morbldity for Schistosoma japonicum infection for 2 islands (large,Qingshan; small, Nianjiashan )in the Dongting lake region, Hunan Province was reported in 1996. A total of 1909 individuals representing 72. 2% of the local population were examined.Kato-Katz thick smear stool examinations revealed that the prevalance on the large and small islands was 14. 6% and 23. 7%, respectively. Two distinct peaks prevalence were observed at age 25-34 and age 45-54 for the large island. The age specific prevalence peaks on the small island were,later than those observed in the large island. The distribution pattern of intensity among infected individuals was 71. 1% for those lightly infected (8 - 100epg);21. 3% for moderately infected (101 -400epg) individuals and 7. 6% for those heavily infected (>400 epg ). The prevalence of hepatomegaly and splenomegaly was 21. 9% and 1. 3%,respectively. There was no significant correlation between the prevalence for S. japonicum and egg output. The occurrence of hepatomegaly and diarrhoea was more frequently observed among those heavily infected persons than those uninfected or lightly infected individuals. Fishermen had the highest prevalence rate (22. 4% )among all the occupational groups examined but students produced the highest worm burdents(intensity) at 220 eggs per gram (epg). The results of thls study indicate that current control strategies are insufficient for reducing the incidence of this diseases significantly.
