Final answer:
Clinical contact surfaces of HBV can be directly contaminated from patient materials via direct contact or contact with gloved hands.
Step-by-step explanation:
The clinical contact surfaces of HBV, such as medical equipment or furniture, can be directly contaminated by patient materials via direct contact or through contact with gloved hands. For example, if a patient's blood or body fluids come into direct contact with the surface, it can lead to contamination. Likewise, if a healthcare worker touches the contaminated materials with gloved hands and then touches the surfaces, contamination can also occur.
