What it means
Sexually transmitted infections (STIs) are infections spread primarily through sexual contact. Common STIs include chlamydia, gonorrhea, syphilis, herpes, HPV, and HIV. Many STIs have no symptoms, making routine screening essential for sexually active individuals. Untreated STIs can lead to serious complications including infertility, chronic pain, increased cancer risk, and transmission to others including newborns. Treatment depends on the specific infection — bacterial STIs like chlamydia and gonorrhea are curable with antibiotics, while viral infections like herpes and HIV are manageable but not curable. Condoms and vaccines (HPV, hepatitis B) help prevent transmission.
