Sexualy transmitted infections (STIs) are mainly spread through exchange of bodily fluids (like semen, vaginal secretions), skin - to - skin contact (for some STIs like HPV in genital areas), blood - to - blood contact (e.g., sharing needles with infected blood which can have STI - causing agents in some cases) and during childbirth (mother - to - child transmission).
