The epidemic of major sexually transmitted diseases in Shanghai, China, 2009-2018.

Acquired immune deficiency syndrome (AIDS), hepatitis B virus (HBV), hepatitis C virus (HCV), gonorrhea and syphilis are the major sexually transmitted diseases (STDs) in the world, which are the focus of epidemic prevention and control in China. The epidemiological trend analysis of STDs in Shanghai could reflect the epidemic situation of these diseases in high-income areas of China, providing a reference for how to control their epidemic. Although the overall incidence rate of infectious diseases levelled off after 2009, Shanghai still faces many new obstacles in the fight against STDs. Without effective prevention and control strategies for high-risk behaviors, such as active sexual activity without protection, for key susceptible populations, there may be a more serious epidemic of STDs in the future. Given these situations, strategies for controlling STDs in Shanghai should be more targeted with the development of epidemics, focusing on the following key areas for future work: i) attaching importance to health education; ii) strengthening epidemic surveillance; and iii) developing Community Health Service Centers (CHSC) as intervention subjects.
