in relation to HIV prevention explains the following PEP and PrEP?

PEP stands for post-exposure prophylaxis, which is a short-term treatment taken after potential exposure to HIV to prevent infection. PEP should be started as soon as possible, ideally within 72 hours of exposure, and consists of a 28-day course of antiretroviral medications.

PrEP stands for pre-exposure prophylaxis, which is a daily medication taken by HIV-negative individuals to reduce their risk of contracting HIV. PrEP is highly effective when taken consistently and as prescribed, and is recommended for individuals at high risk of HIV infection, such as those in serodiscordant relationships or who engage in high-risk behaviors.
