Which of the following statements regarding routes of exposure to HBV is correct?

The correct statement regarding routes of exposure to Hepatitis B Virus (HBV) is that percutaneous and mucous membranes are primary routes. HBV is primarily transmitted through direct exposure to infected blood and bodily fluids. This can occur through breaks in the skin, such as needlesticks or cuts (percutaneous routes), or through exposures to mucous membranes, such as in the case of sexual contact or contact with infected blood on mucous tissues.

Understanding these primary routes is crucial for implementing effective bio-safety measures, as they inform how healthcare workers and individuals can protect themselves against infection. Recognizing that HBV is not primarily transmitted through ingestion or airborne means helps clarify that strategies like good hygiene and safe handling of blood products are key in preventing transmission. The focus on percutaneous and mucous membrane exposure helps underscore the importance of personal protective equipment (PPE) and proper disposal of needles and sharps in healthcare settings.
