Which statement, from a participant attending the class on AIDS prevention, indicates an understanding on how to reduce transmission of HIV?
Correct Answer: B
Rationale: The correct answer is B because implementing a needle exchange program is an effective way to reduce transmission of HIV among intravenous drug users. By providing clean needles in exchange for dirty needles, the risk of sharing contaminated needles and spreading the virus is significantly reduced. This approach also helps prevent the transmission of other bloodborne diseases, such as Hepatitis C. The other statements do not demonstrate an understanding of how to reduce HIV transmission - for example, encouraging breastfeeding for HIV-positive mothers can transmit the virus to the baby, birth control pills do not protect against HIV, and natural skin condoms do not offer the same level of protection as latex condoms.
