Answer:
Alcohol increases the risk by impairing your judgment.
Explanation:
Alcohol has a detrimental effect on your judgment, and may cause you to adopt dangerous attitudes or behaviors without being aware that you may be injured.
As we know, the most common way to get HIV is through unprotected sex, ie without the use of condoms. We are all aware that unprotected sex is dangerous, but under the influence of alcohol, our judgment is flawed and we may forget and end up having unprotected sex, at high risk of contracting HIV.
