Post-exposure Prophylaxis (PEP)

Post-exposure prophylaxis (PEP) is a form of medical emergency treatment to prevent infection following an exposure to a virus. It is most commonly used following contact with HIV, and can also be used for other viruses or bacteria, such as hepatitis B and C, rabies, and the influenza virus. PEP is aimed at preventing an infection from taking hold, and is generally most effective when initiated within a few hours or days of the exposure. It is important for health professionals, including doctors and nurses, to be aware of the use and effectiveness of PEP for their patients. PEP provides an important additional layer of protection to individuals at risk of HIV, and is a critical tool in the fight to control the spread of HIV.
