What is PrEP used for in the context of HIV?

Pre-exposure prophylaxis (PrEP) is a preventive strategy for individuals who are at high risk of contracting HIV. The medication works by significantly reducing the risk of HIV infection when taken consistently and as prescribed. It is specifically designed for those who are HIV-negative and may be exposed to the virus through sexual contact or sharing needles.

PrEP involves the use of antiretroviral medications to prevent the establishment of HIV in the body following potential exposure. Studies have shown that when taken regularly, PrEP can lower the risk of getting HIV from sexual activity by about 99%. It is an important tool in public health efforts to reduce the spread of HIV and is particularly beneficial for those who engage in behaviors that may increase their risk of infection.

The other options mentioned serve different purposes. Treating active HIV infections is managed with antiretroviral therapy rather than PrEP. Additionally, there is currently no cure for HIV, and increasing viral load is contrary to the goals of HIV management and prevention strategies. Thus, the role of PrEP is clearly defined as a prevention method, making it a critical component in the fight against HIV transmission.
