[Objective]To analyze the epidemiological characteristics of gonorrhea and syphilis in China from 1991 to 2006 and provide scientific basis for formulating prevention and control measures.[Methods]National data on the prevalence of syphilis and gonorrhea from 1991 to 2006 were collected and analyzed.[Results]The incidence for gonorrhea in China showed to be an increasing trend from 1991 to 1999,the highest level was 22.78/105 in 1999,then a decreasing trend were occurred during 1999 to 2006. The number of cases with syphilis reported continually increased from 1991 to 2006,especially obviously increased after 2005. The number of reported cases of syphilis(175,000)was more than gonorrhea(162,000)in 2006;The number of cases with syphilis(175,000)reported was more than that of gonorrhea(162,000),of which the syphilis latent reported showed to be the fast increasing trend. The syphilis latent had the largest proportion(38.52%)in all types of syphilis in 2006.[Conclusion]The syphilis had the highest incidence among all the venereal diseases.
