Timing of Potential HIV Acquisition in People Prescribed HIV PrEP
David H. Spach, MD discusses how a person can acquire HIV when prescribed HIV PrEP during these three time periods: prior to starting HIV PrEP, taking HIV PrEP, and after discontinuing it. He reviews how three baseline tests vary on when they can accurately detect HIV soon after a recent HIV infection. Using illustrations, he then examines why and when some people may acquire HIV while taking oral or injectable HIV PrEP or after they discontinue those medications.
