Sharing needles is a significant risk factor for transmitting Hepatitis B because this virus is primarily spread through contact with infectious body fluids, such as blood. When individuals share needles, they increase the likelihood of exposure to contaminated blood, which can carry the virus. This mode of transmission is particularly concerning among individuals who inject drugs, as they may not only share needles but also other equipment such as syringes and vials.

The other options listed, while they may pose risks for other infections or illnesses, do not significantly correlate with the transmission of Hepatitis B. For instance, eating contaminated food is more commonly associated with foodborne illnesses, while drinking unclean water typically relates to gastrointestinal diseases. Additionally, while pets can carry various zoonotic diseases, they are not a recognized vector for Hepatitis B transmission in humans. Understanding these distinctions is crucial for recognizing how Hepatitis B spreads and implementing effective prevention strategies.
