First of all, there is no evidence that people infected with HIV can be cured by the currently available therapies. In fact, individuals who are treated for years and are repeatedly found to have no virus in their blood experience a prompt rebound in the number of viral particles when therapy is discontinued. Consequently, the decision to start therapy must balance the risk versus the benefits of treatment. The risks of therapy include the short- and long-term side effects of the drugs, described in subsequent sections, as well as the possibility that the virus will become resistant to the therapy which can limit options for future treatment.
