With regard to the transmission of the Human Immunodeficiency Virus, which one of the following statements is not correct?
- A.The chances of transmission from female to male are twice as likely as from male to female
- B.The chances of transmission are more if a person suffers from other sexually transmitted infections
- C.An infected mother can transmit the infection to her baby during pregnancy, at childbirth and by breast feeding
- D.The risk of contracting infection from transfusion of infected blood is much higher than an exposure to contaminated needle
▶ Answer & Explanation
Correct answer: A. The chances of transmission from female to male are twice as likely as from male to female
The statement that transmission from female to male is twice as likely as from male to female is factually incorrect. Transmission rates are generally higher from male to female during unprotected heterosexual intercourse due to biological factors. The presence of other STIs can indeed increase HIV transmission risk by creating sores or inflammation. Mother-to-child transmission is a well-documented route, occurring during pregnancy, labor, or breastfeeding. Transfusion of infected blood poses a very high risk of HIV transmission, significantly greater than needlestick injuries.
