摘要:   目的 分析大理市 1995年达到血吸虫病传播控制标准后 5年间的疫情变化。 方法 收集 1995~ 2 0 0 0年的血吸虫病流行病学数据 ,并进行统计、对比和分析。 结果  1995~ 2 0 0 0年 ,大理市人群粪检阳性率逐年升高 ,每年均有 14岁以下血吸虫病患者和新感染者。 1996~ 1998年连续发生急性血吸虫感染病例 ,耕牛粪检阳性率处于波动状态。1996年有螺面积扩大 ,1997~ 2 0 0 0年阳性螺点均维持在较高水平 (每年大于 2 0 0点 )。 结论 大理市血吸虫病疫情呈回升趋势 ,可能的原因包括服药率低 ,家畜流动频繁及灭螺不力等。

Abstract:

 Objective To analyze the epidemic situation on schistosomiasis in five years after reaching the criteria of transmission control in 1995 in Dali City. . Methods. Epidemiological data of schistosomiasis during 1995-2000 were collected and analyzed. . Results . Stool positive rate in the population was increasing yearly, new cases of infection including cases under 14 years old were detected each year. Acute infection occurred during 1996-1998 consecutively. Stool positive rate in cattle was unstable. Snail-ridden area increased significantly in 1996 and spots with infected snails stayed at a higher level during 1997-2000. . Conclusion . Schistosomiasis in Dali city has been re-emerging though it was once deemed under transmission control. Possible reasons include a low drug-taking rate though distributed, frequent movement of cattle population, and less activity on snail control.
