What are the most common STDs?
While there are a range of sexually transmitted infections, the most prevalent include:
- Chlamydia: A bacterial infection that is most often spread through unprotected sex
- Gonorrhea: A bacterial infection that can infect the rectum, throat, urethra, and cervix.
- Syphilis: A bacterial infection that starts as a painless sore on the mouth, rectum, or genitals, and is spread from contact with these sores via your mucous membrane or skin.
- Trichomoniasis: A parasite that can transfer between people during sex.
- Genital warts: An infection caused by certain strains of HPV, which can affect the moist tissues of the genitals.
- Hepatitis B (HBV): HBV is a virus that is spread between people through body fluids such as blood and semen. This means it's transmissible through sexual contact and sharing needles.
- Human immunodeficiency virus (HIV): HIV is the virus that causes AIDS. The HIV/AIDS virus can break down certain cells of your immune system, leaving you increasingly susceptible to infections and illnesses. HIV/AIDs can be fatal.
- Human papillomavirus (HPV): Pelvic inflammatory disease that has the potential to cause cancer in women and men.
- Herpes simplex virus: Herpes is a viral infection that can result in sores on your mouth and/or genitals. Herpes of the mouth and genital herpes, though painful or annoying at times, does not usually lead to other serious health problems.
Leaving any of these STIs untreated can cause serious health problems.
