Universal access to onsite rapid HIV testing with early initiation of therapy for infected persons, universal precaution training, safer sex education, safe blood supply and needle exchange programs, and the consideration of pre-exposure antiviral prophylaxis (PrEP) in high-risk situations, are all are important aspects of effective and necessary preventive strategies. However, in cases where exposure has already occurred, it is possible to decrease the risk of transmission of HIV infection through the use of postexposure prophylaxis (PEP).
