Which of the following is a non-medical intervention that can help reduce HIV transmission?

Comprehensive sex education is a vital non-medical intervention that can significantly help reduce HIV transmission. This form of education provides individuals with essential knowledge about sexually transmitted infections, including HIV, and promotes safer sexual practices. By teaching individuals about the importance of using condoms, understanding consent, recognizing the risks associated with various sexual behaviors, and encouraging open communication about sexual health, comprehensive sex education empowers individuals to make informed decisions, ultimately leading to a decrease in HIV transmission rates.

The option of providing antiretroviral therapy primarily falls under medical interventions aimed at treating HIV, not prevention. Offering free HIV testing is crucial for detection and initiating treatment but does not directly prevent transmission. Conducting medical research on vaccines is important for future prevention strategies but does not constitute an immediate non-medical intervention. Comprehensive sex education stands out as a proactive approach that enhances public health efforts to reduce transmission effectively.
