Results There were 526 cases of leptospirosis, 18 of which were died and the annual incidence was 1.32/lakh in Yichang from 1997 to 2006. The high-risk group was the males aged from 20 to 50 years old, especially the peasants. And the peak periods were August and September, while there were different incidence in different zones and the highest was Zhijiang. Conclusion The incidence trend of leptospirosis was generally downward in Yichang from 1997 to 2006.
