PrEP (Pre-Exposure Prophylaxis) is a method of using antiviral medication before potential HIV exposure to reduce the risk of infection. WHO defines PrEP as “the use of anti-HIV medication by HIV-negative people to reduce the risk of HIV acquisition” [<\/span>1<\/span><\/a>]. Conversely,\u00a0<\/span>PEP (Post-Exposure Prophylaxis)<\/span><\/a>\u00a0is medication taken for 28 days after a potential HIV exposure situation, which must be started as soon as possible (ideally within 24 hours, a maximum of 72 hours post-exposure) [<\/span>2<\/span><\/a>]. PrEP is used as a long-term, ongoing preventative measure (usually daily or on-demand), whereas PEP is an emergency post-exposure intervention.<\/span>
