There are a number of stages in the HIV lifecycle where infection and spreading can be interrupted, but ideally HIV needs to be stopped before the viral DNA is integrated into the host genome. A number of prevention methods have been created and tested by scientists; however few have yet been successful in preventing HIV infection. In this section, some prevention strategies for HIV will be discussed and the advantages and disadvantages of each method will be considered.
