Sexually transmitted infection
Sexually transmitted infections (STI), also referred to as sexually transmitted diseases (STD), are infections that are commonly spread by sexual activity, especially vaginal intercourse, anal sex and oral sex.Many times STIs initially do not cause symptoms. This results in a greater risk of passing the disease on to others. Symptoms and signs of disease may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. STIs can be transmitted to an infant before or during childbirth and may result in poor outcomes for the baby. Some STIs may cause problems with the ability to get pregnant.
