STDs (sexually transmitted diseases) are infections that are mostly spread through sexual activity, including vaginal, oral, and anal sex. Some infections can be spread through close personal contact, such as kissing, or from a mother to her unborn child.
STDs are caused by bacteria, viruses, or parasites. Millions of Americans are infected with some type of STD every year, with half of diagnoses occurring in teens and young adults between the ages of 15 and 24. Common STDs include chlamydia, gonorrhea, genital herpes, HIV, and HPV (human papillomavirus) infection.
Left untreated, certain STDs can cause devastating and long-term health problems such as blindness, brain damage, infertility, birth defects, and even death. Fortunately, all STDs can be treated, and some can be cured entirely. STD testing can help you get diagnosed and treated so you may avoid serious complications.
