What is the approximate transmission rate of HIV from a single occupational needlestick exposure?
Show answer and explanation
Correct answer: A. 0.3%
The widely cited average risk of HIV transmission after a single percutaneous (needlestick) exposure to HIV-infected blood is approximately 0.3% — a well-established occupational health statistic, much lower than the transmission risk associated with hepatitis B or hepatitis C exposures.
