What is the HIV viral load?
This is a measure of how much replicating HIV is found in the circulating blood. In a HIV positive person this usually varies from a few hundred to a few million copies/ml. In patients on HIV treatment, the viral load is an accurate measure of how effective treatment is. The aim on treatment is to reach an “undetectable” level. Please note having an undetectable viral load does not mean the person is not infectious – he/she can still transmit HIV to others.
