The origin of sexually transmitted infections (STIs) must be analyzed according to the specific type of infection. Gonorrhea is primarily caused by infection with *Neisseria gonorrhoeae*; syphilis is typically caused by infection with *Treponema pallidum*; and AIDS (acquired immunodeficiency syndrome) is caused by human immunodeficiency virus (HIV) infection—not HPV (human papillomavirus), which causes other conditions such as genital warts and certain cancers. Primary modes of transmission include sexual contact and indirect contact.
