HIV treatment and an undetectable viral load to prevent HIV transmission
It is now well known that the use of HIV treatment not only improves the health of people living with HIV but also is a highly effective strategy to prevent HIV transmission. This is because HIV treatment can reduce the amount of virus (viral load) in the blood and other bodily fluids (such as semen and vaginal and rectal fluids) to undetectable levels. To achieve and maintain an undetectable viral load, people living with HIV need to take their HIV treatment as prescribed. In addition to taking HIV medications, regular medical visits are important to monitor viral load to make sure it stays undetectable and to receive other medical support.
