Abstract: In order to find out the main area and crowd infected by leptospirosis and the main epidemic leptospir serogroups in the three gorge reservoir area, 513 serum samples were collected from healthy people in 7 monitoring places in 1998 and leptospira antibody was examined. Results showed that 165 cases were positive (32.16%), from 11.11% to 50.00% in different areas. The infection was interrelated to age but not to sex. There were 9 serogroups of leptospira antibody identified in this study. Icterohaemorrhagiae serogroups were the dominant serogroup. All of the serogroups antibody in the throng of people in lower level. It suggests that the surveillance of leptospirosis need to be strengthened and a comprehensive strategy including effective management and control leptospirosis need to be developed in the three gorge reservoir area.
