Sexually Transmitted Infections - TSV
Sexually transmitted infections (STIs) are a general term for infections primarily transmitted through sexual activity. In Japan, surveillance is conducted for five diseases: syphilis, gonococcal infection, genital chlamydia infection, genital herpes virus infection, and condyloma acuminatum. In recent years, particularly syphilis cases have surged dramatically, reaching a record high of 14,906 cases in 2023. Many STIs can be cured with early detection and appropriate treatment, but if left untreated, they can cause infertility and serious complications.
