Teens, Sexually Transmitted Diseases and HIV/AIDS

STD stands for Sexually Transmitted Disease (sometimes called Sexually Transmitted Infection). This is an infection which can be caught by having sexual contact with someone who is infected. This can be vaginal, oral or anal sex, although other types of touching can pass some STDs - for example, some STDs (such as Herpes and HPV) can be caught by touching the infected areas of someone's body and then touching your own genitals (private parts). There are quite a lot of different STDs.
