Sexually Transmitted Infections (STIs) are diseases mainly spread through unprotected sexual contact, blood transmission, or from mother to baby during childbirth. They are caused by bacteria, viruses, fungi, or parasites. Many STIs show no symptoms but can lead to serious complications if left untreated. Prevention includes practicing safe sex, using protection, getting HPV and Hepatitis B vaccines, and having regular health screenings.
