STIs & HIV/AIDS
- Unprotected sexual intercourse can lead to the transfer of pathogens via exchange of body fluids
- Infections passed on in this way are known as sexually transmitted infections (STIs)
- An example of an STI is HIV (Human Immunodeficiency Virus), the virus that usually leads to the development of acquired immunodeficiency disease (AIDS)
- HIV can also be spread via sharing needles with an infected person, blood transfusions with infected blood and from mother to fetus through the placenta and mother to baby via breastfeeding
