Sexually transmitted infections (STIs) are infections or conditions that can be contracted through sexual contact. They can be caused by bacteria, viruses, or parasites, and can be spread through vaginal, anal, or oral sex. Some STIs can also be transmitted from mother to child during pregnancy, childbirth, or breastfeeding).

STIs can have serious health consequences if left untreated, including infertility, chronic pain, and an increased risk of HIV transmission. Some STIs, such as chlamydia, gonorrhea, syphilis, and trichomoniasis, are curable with antibiotics). Others, such as HIV, herpes, and human papillomavirus (HPV), are incurable but can be managed with medication).

Common symptoms of STIs include abnormal discharge from the vagina, penis, or anus, pain during urination, genital ulcers or lumps, lower abdominal pain, and itching or burning around the genitals or anus. However, many STIs have no symptoms at all, which is why regular STI screenings are recommended for sexually active individuals.

Prevention of STIs includes practicing safe sex, such as using condoms and dental dams, getting vaccinated against HPV, and getting tested regularly for STIs. If you suspect you have an STI, it is important to seek medical attention as soon as possible to prevent further transmission and complications.
