Sexually Transmitted Infection (STI)

A sexually transmitted infection (STI) is a infection that spreads mainly through sexual contact, including vaginal, oral, or anal sex. STIs are caused by bacteria, viruses, or parasites, and some may show no symptoms initially. Common STIs include chlamydia, gonorrhea, syphilis, herpes, HIV, and human papillomavirus (HPV). If left untreated, some STIs can lead to serious health problems, such as fertility issues or increased risk of other infections. Preventive measures include using protection like condoms, regular testing, and open communication with sexual partners. Early diagnosis and treatment are important to manage STIs effectively.
