Genital herpes is common in the United States. It is caused by two types of viruses, herpes simplex type 1 (virus usually responsible for cold sores) and herpes simplex type 2 (typically affects genital area). However, both types can cause either oral or genital infections. About one out of every six people aged 14 to 49 years in the United States have genital herpes.
HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease.
HPV is the most common sexually transmitted infection (STI). You can get HPV by having vaginal, anal, or oral sex with someone who has the virus. It is most commonly spread during vaginal or anal sex. HPV can be passed even when an infected person has no signs or symptoms.
