Sexually transmitted infections no joke
Sexually transmitted infections (STIs) are mostly acquired by sexual contact. The organisms that cause sexually transmitted diseases may pass from person to person through blood, semen or vaginal and other bodily fluids. STIs commonly (but not exclusively) include Human Papilloma Virus (HPV), chlamydia, herpes, gonorrhoea and, less frequently, HIV and syphilis. Occasionally, STIs can be transmitted non-sexually too, such as from mother to infant during pregnancy or childbirth.
