All samples further diagnosis of active disease. Results From a total 4027 attendees, 3213 (79.78%) FSW, 229 (5.69%) MSM 585 (14.53%) HRH. The proportion HRH had single visit 56.42%, 57.23% 91.10%, respectively. Overall, 2.10% 8.17% 4.12% Prevalence decreased FSW. gonorrhoea did not decrease time neither FSW nor Chlamydia trichomonas showed increase trend. In condom use last intercourse regular occasional clients above 93%. Conclusions show decreasing trend HIV, prevalence. Gonorrhoea time. is hard engage population low follow-up rates high potential act bridge population.
