[The sero-epidemiological investigation of leptospirosis in Hainan Province].
This paper reported that 529 serum samples were collected from healthy people in ten townships of nine cities or counties of Hainan Province in 1993 and anti-leptospira antibody was examined. Results showed that 274 cases were positive (51.8%), indicating the natural infection rates were from 25.9% to 72.2% in different areas. The infection was irrelevant to sex, but was interrelated to age and occupations. There were 15 serogroups of anti-leptospira antibody identified in this study. Bataviae, Grippotyphosa and Icterohaemorrhagiae serogroups were the dominant serogroups, different from that the Grippotyphosa and Autumnalis serogroups as the superior serogroups in the 1970s. Data shows that the main epidemic serogroups are likely to change, which suggests that the surveillance of leptospirosis needs to be strengthened.
