Sexually Transmitted Infection

Sexually Transmitted Infection (STI) is an infection passed from one person to another person through sexual contact. STIs are also called sexually transmitted diseases, or STDs. STIs are spread predominantly by sexual contact, including vaginal, anal and oral sex. Some STIs can also be spread through non-sexual means such as via blood or blood products or from mother to child during pregnancy and childbirth. A person can have an STI without having obvious symptoms of disease. Common symptoms of STIs include vaginal discharge, urethral discharge or burning in men, genital ulcers, and abdominal pain.
