My answer is semen and blood to blood. Am I correct?

yes.

Yes, you are correct. Semen and blood-to-blood contact are two ways you can contract bloodborne pathogens. Semen can transmit bloodborne viruses, such as HIV or hepatitis, during sexual intercourse or through contact with open wounds. Similarly, blood-to-blood contact can occur through sharing contaminated needles or other sharp objects, receiving blood transfusions or organ transplants from an infected donor, or through accidental needlestick injuries in healthcare settings. It's important to practice safe behaviors and take necessary precautions to prevent the transmission of bloodborne pathogens.
