Which type of STI is typically transmitted through body fluids?

Sexually transmitted infections (STIs) are categorized based on their causative agents: bacterial, parasitic, and viral. All of these types can be transmitted through body fluids, making "All of the above" the correct choice.

Bacterial STIs, such as chlamydia and gonorrhea, can spread through sexual contact involving the exchange of bodily fluids. Similarly, viral STIs like HIV and herpes can also be transmitted through fluids such as blood, semen, and vaginal secretions. Parasitic STIs, which include infections like trichomoniasis, can be spread through sexual contact as well, as they often involve the transfer of bodily fluids during intercourse.

Understanding that these three types share this transmission method is critical in addressing and preventing these infections, emphasizing the importance of safe sexual practices.
