PrEP stands for pre-exposure prophylaxis. The idea is to prevent HIV infection by taking an antiretroviral medication before a potential exposure, and it’s targeted to people who are at ongoing risk. When taken consistently, PrEP substantially lowers the chance of acquiring HIV if exposure occurs. This is different from post-exposure prophylaxis, which is taken after a possible exposure to reduce risk, and needs to be started promptly. The other terms mentioned aren’t standard names for this preventive strategy.
