This fact sheet shares prevention and general fact information regarding  sexually transmitted infections (STIs), which are infections primarily caused by bacteria and viruses spread from person to person during vaginal, oral, or anal sex or other intimate contact. Some STIs, such as herpes and HPV, are spread through skin-to-skin contact. 

Sexually Transmitted Infections (STIs)

This webpage explains that more than 30 different bacteria, viruses and parasites are known to be transmitted through sexual contact, including vaginal, anal and oral sex.
