Sexually Transmitted Infection (STI)

A sexually transmitted infection (STI), also known as a sexually transmitted disease (STD), is an infection that is passed from one person to another through sexual contact. STIs can be caused by bacteria, viruses, or parasites and are spread through vaginal, anal, or oral sex, as well as skin-to-skin genital contact. Some common examples include chlamydia, gonorrhea, syphilis, HIV/AIDS, and herpes.

Additional Information

Many STIs may not cause noticeable symptoms, which is why regular testing is important for sexually active individuals. If left untreated, STIs can lead to serious health complications such as infertility, pelvic inflammatory disease, and increased risk of certain cancers. Prevention methods include using condoms, practicing monogamy, and getting vaccinated for certain STIs like HPV. Treatment options vary depending on the specific infection but often involve antibiotics or antiviral medications.
