安徽省1993至1997年钩端螺旋体病疫情及趋势分析

Analysis on the Epidemic Trend of Leptospirosis in Anhui Province 1993-1997

目的：掌握近５年钩端螺旋体病（钩体病）流行趋势。方法：对淮北平原、江淮丘陵、皖南山区３个流行区的疫情资料进行统计分析。结果：皖南山区是主要流行区和高发地区，疫区稳定，发病的季节性非常明显，９～１０月是流行的高峰时段，与全省钩体病发病的季节性完全一致，该地区钩体病发病数可左右全省疫情；淮北平原和江淮丘陵地区钩体病流行的季节性不明显，全年都有病例发生。在１４９７例钩体病例中，男与女之比为１．８∶１，１０～４９岁年龄组占８７．７８％，农民占７９．７６％。人群发病构成的差异，主要是由于接触钩体病疫水的次数多少、时间长短和频率高低所致，并提出了针对性预防措施。结论：本省钩体病防制工作的重点为皖南山区。
