Question map
With regard to the transmission of the Human Immunodeficiency Virus, which one of the following statement if not correct?
Explanation
Option 1 is not correct. Epidemiologic estimates show the per‑exposure risk for receptive penile–vaginal intercourse (male-to-female transmission) is about 10 per 10,000 exposures, while insertive penile–vaginal intercourse (female-to-male) is about 5 per 10,000 — indicating male-to-female transmission is roughly twice as likely as female-to-male, not the reverse [1]. The other statements are accurate: concomitant sexually transmitted infections increase HIV susceptibility and transmissibility (estimated 2–4×); infected mothers can transmit HIV during childbirth and through breastfeeding [2]; and transfusion of contaminated blood carries a much higher per‑exposure transmission risk than percutaneous needle exposures (supporting option 4) [1].
