Sexually transmitted infections (STIs)
Sexually transmitted infections (STIs) are infections that are spread primarily through person-to-person sexual contact. Several, in particular HIV and syphilis, can also be transmitted from mother to child during pregnancy and childbirth, and through blood products and tissue transfer.
The most common conditions they cause are gonorrhoea, chlamydial infection, syphilis, trichomoniasis, chancroid, genital herpes, genital warts, human immunodeficiency virus (HIV) infection and hepatitis B infection.
There are more than 30 different sexually transmissible bacteria, viruses and parasites. STIs can also cause serious health problems such as infertility, stillbirth, and blindness in newborns.
