What is a common route of hepatitis B transmission?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Blood and body-fluid exposure

The central Virology concept identifies Blood and body-fluid exposure as the best answer because it directly explains the mechanism, indication, adverse effect, or organism feature described.

Option by option

  • A. Fecal-oral route only

    Fecal-oral route only has another context but is not the most appropriate answer here.

  • B. Blood and body-fluid exposure (correct)

    Correct. Blood and body-fluid exposure matches the decisive point in this scenario.

  • C. Casual skin contact

    Casual skin contact is unsupported by the mechanism or clinical clue in the stem.

  • D. Mosquito bite

    Mosquito bite does not fit the stated virology relationship.
