**Core Concept**
Hepatitis B virus (HBV) is a major public health concern, transmitted through various routes that involve direct contact with infected bodily fluids. The virus primarily targets the liver, leading to inflammation and potential liver damage.
**Why the Correct Answer is Right**
HBV can be transmitted through parenteral routes, including needlestick injuries, blood transfusions, and sharing of contaminated needles. It can also be spread through sexual contact, vertical transmission from mother to child during childbirth, and through contaminated bodily fluids, such as blood, semen, and saliva. This highlights the importance of proper infection control measures and safe sex practices to prevent HBV transmission.
