Sexually transmitted diseases: incidence and distribution
1National Center for STD and Leprosy Control, Institute of Dermatology, PUMC & CAMS, Nanjing.
Summary
Sexually transmitted disease (STD) rates significantly increased in China between 1987 and 1993. While gonorrhea remains common, increases in nongonococcal urethritis and genital warts, alongside resistant strains and Chlamydia, pose challenges to STD control efforts.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Sexually transmitted diseases (STDs) represent a significant public health concern.
- Monitoring STD incidence and trends is crucial for effective control strategies.
- Specific STDs like gonorrhea, chlamydia, and syphilis require ongoing surveillance.
Purpose of the Study:
- To analyze the epidemiological trends of STDs in selected areas of China.
- To identify changes in the relative proportions of different STDs.
- To highlight challenges in STD treatment and control.
Main Methods:
- Retrospective analysis of STD incidence data from 1987 to 1993.
- Comparison of STD rates and disease distribution over the study period.
- Identification of specific pathogens and risk factors.
Main Results:
- Overall STD incidence rose from 26.04 to 104.81 per 100,000 population.
- Gonorrhea's proportion decreased due to rising rates of nongonococcal urethritis and genital warts.
- Increasing prevalence of resistant Neisseria gonorrhoeae and Chlamydia trachomatis infections noted.
Conclusions:
- China faces a growing challenge in controlling STDs, marked by rising incidence and evolving pathogen profiles.
- Drug-resistant gonorrhea and Chlamydia infections necessitate revised therapeutic and control strategies.
- Coordinated national efforts are underway to address the escalating STD epidemic.
