    Abstract:
    OBJECTIVE: In order to explore current epidemic situation of sexually transmitted diseases (STD), especially its trends and related factors as the basis for working out the STD control program, a sentinel surveillance system was established in the period 1993-1996. METHODS: Through adjustment of 26 sentinel sites based on the original STD prevalent in 16 surveillance cities were selected. The management was strengthened (such as supervision and feedback) and specific surveys were conducted in sentinel sites. RESULTS: During the 4-year period, 202,866 cases were reported. The average annual incidence was 141.46/100,000. Although the incidence increased year by year, the growing rate showed somewhat of slowdown as compared with the past. Despite of more male cases reported, the male-to-female ratio behaved downwards. The group aged 20-39 accounted for 82.37% of total cases; however, STD in children came into a marked increase over the previous year. STD incidence was the highest in the urban areas (181.86/100,000). The major disease still was gonorrhea but its incidence began to decline. Syphilis (including in children) had a fast rate of increase. Several HIV/AIDS cases were initially reported in sentinel sites. Among the sources of infection, clandestine prostitutes occupied a relative important position. CONCLUSIONS: Because of strict management the data collected from sentinel sites could be accurately described. For further improvement of the sentinel surveillance system, several suggestions are proposed.
