Final answer:
Transmission of blood or body fluids requiring direct contact, casual contact like handshakes or coughing typically do not transmit bloodborne diseases.
Step-by-step explanation:
The transmission of blood or body fluids through touching (including shaking hands), kissing, coughing, sneezing, and talking does not typically occur. Various pathogens, such as those causing sexually transmitted infections (STIs), require direct contact between mucous membranes to spread. These pathogens generally cannot infect via non-sexual skin contact. Moreover, certain myths, like HIV being transmitted through casual contact like kissing or sneezing, have been debunked. Transmission of bloodborne diseases typically requires more direct contact with infected body fluids, such as through blood transfusions, IV drug use, sexual transmission, or from infected mother to child during pregnancy, childbirth, or breastfeeding. It's essential to recognize that while casual contact does not usually pose a risk for bloodborne infections, following proper hygiene and precautions is crucial in healthcare settings or when in close contact with infected individuals.
