Reducing the risk of HIV transmission
Antiretroviral therapy (ART) has the potential to lower HIV incidence at the population level and to decrease prevalence by preventing secondary transmission of HIV. In 3 studies, including the PARTNER study, there were no documented cases of transmission between someone who was virally suppressed and their partner who was HIV negative, even after reporting unprotected sex.1-4
Undetectable viral load = effectively no risk of HIV transmission3
The sooner viral suppression is achieved, the shorter the period during which transmission can occur. Modelling studies indicate that incidence and prevalence of HIV on a community or population level might be lowered by expanded use of ART.2
What your patients need to know about treatment as prevention1,3,5
1-6 months is the time required to achieve an undetectable viral load
6 months (from the first undetectable test result) is the time required to maintain an undetectable viral load
If a patient achieves and maintains an undetectable viral load, there is effectively no risk of transmitting HIV
Adapted from NIAID.
So, the idea is that with [the patient’s] antiretroviral regimen and good adherence, they can maintain viral suppression, therefore reducing their risk of transmission."
