PrEP, or pre-exposure prophylaxis, is a medication taken by individuals at high risk of contracting HIV. When taken consistently, it can reduce the risk of getting HIV from sexual activity by up to 99%. It is an important tool in the fight against HIV/AIDS and is recommended for those with partners who are HIV positive or for those who have multiple sexual partners. To be effective, PrEP must be taken daily, and regular medical check-ups are necessary to monitor HIV status and overall health. It is not a cure for HIV, but when combined with other prevention methods, such as condoms, it can significantly lower the chances of infection.
