Final answer:
The most likely body fluids to cause HBV infection are blood, semen, and vaginal secretions. Sweat is not typically a fluid through which HBV is transmitted. Protective measures and proper disinfection practices are vital in health-care settings to prevent HBV transmission.
Step-by-step explanation:
The body fluids most likely to cause HBV infection are blood, semen, and vaginal secretions. While health-care workers need to take precautions to prevent infection from all body fluids, blood is known to be the greatest risk for transmitting HBV. Other body fluids such as semen and vaginal secretions can also transmit the infection. Therefore, avoiding contact with these body fluids by using protective measures such as gloves and face protection, and following detailed protocols for managing exposure, are critical in reducing the risk of HBV transmission.
Sweat is not typically a fluid through which HBV is transmitted, making it the least likely to cause HBV infection from the options provided. Therefore, in medical and health-care settings, particular focus is placed on preventing exposure to blood, semen, and vaginal secretions. It is important to wear proper personal protective equipment and to disinfect surfaces with solutions such as 10% bleach, as recommended by the CDC, to prevent the spread of HBV.
