Someone can be rerived of HIV/AIDS within the first 72 hours of exposure to the disease. This can be done using the Post-Exposure Prophylaxis (PEP).
PEP involves taking anti-HIV medications as soon as possible after you may have been exposed to HIV/AIDS to try to reduce the chance of becoming HIV positive.
Doctors at the World Health Organisation (WHO) have discovered that PEP medications keep HIV/AIDS from making copies of itself and spreading through your body within the first 72 hours of exposure.
There are two types of PEP ie occupational PEP (sometimes called “oPEP”), taken when someone working in a healthcare setting is potentially exposed to material infected with HIV, and non-occupational PEP (sometimes called “nPEP”), taken when someone is potentially exposed to HIV outside the workplace (e.g from sexual assault, or during episodes of unprotected sex or needle-sharing injection drug use).
