Types of STIs

Common sexually transmitted infections

There are at least 20 different STIs. They can be caused by viruses, bacteria, and protozoa. Some of the most common STIs are:

• Chlamydia
• Genital herpes
• Genital warts or human papillomavirus (HPV). Certain high-risk types of HPV can cause cervical cancer in women
• Gonorrhea 
• Hepatitis B 
• Syphilis 
• Trichomoniasis 
• Human immunodeficiency virus (HIV), which causes AIDS. Having other STIs, such as genital herpes, can increase your risk of HIV.
• Other infections that may be sexually transmitted. These include hepatitis A, cytomegalovirus, molluscum contagiosum, Mycoplasma genitalium, hepatitis C, and possibly bacterial vaginosis
• Scabies and pubic lice, which can be spread by sexual contact
