Culture Bound Assumptions in Behavior Intention Models.] abstract - Many models of consumer behavior include fundamental assumptions which are rarely questioned.
PrEP is a course of HIV drugs taken by HIV negative people before sex to reduce the chance of getting HIV. Results in trials have been very successful, with PrEP significantly lowering the risk of becoming HIV positive and without major side effects.
PEP should begin as soon as possible after exposure to HIV but certainly within 72 hours. Treatment with 2 or 3 ARVs should continue for 4 weeks, if tolerated. Researchers are also developing Pre-exposure Prophylaxis (PrEP). PrEP might be used in similar ways as a vaccine.
