Final answer:
Half of all new HIV cases are among people younger than 25 years, which is why the college counselor stresses the importance of safe sex (d). Condom use and comprehensive sex education, including safer sexual practices, are crucial in the efforts to reduce HIV transmission.
Step-by-step explanation:
The college counselor emphasizes safe sex practices because of the high risk of HIV among younger populations. Specifically, half of all new HIV cases are among people younger than 25 years. This is why sexual education often includes information on the use of condoms, which can greatly reduce HIV transmission. It's critical to note that while programs advocating for sexual abstinence have been presented, they do not appear to effectively diminish HIV risks as much as comprehensive sex education that includes safer sexual practices and increased condom use.
Moreover, HIV/AIDS has been a significant public health concern, particularly among young people and in areas with high poverty where access to healthcare is limited. Hence, the focus on safe sex is not just about preventing HIV but also about addressing its broader effects on public health and society.
