Methods The SWs in the same area were investigated for 3 consecutive years. Blood samples were collected to detect HIV antibody and syphilis.

There was significant difference in the proportion of condom patients who used condom when they received more than 3 times of health consultation and 3 times of last transaction (χ2 = 53.12, P <0.05; χ2 = 44.10, P <0.05). The number of syphilis ELISA positive cases and the number of gynecological symptoms increased year by year. The prevalence of syphilis (TRUST positive) was 8.1%, 11.4% and 7.0% respectively, with no significant difference. All collected samples did not detect HIV antibody.
