If your viral load is very low, it may be described as “undetectable”1. An undetectable viral load generally means there are less than 50 copies of HIV-1 RNA per millilitre of blood.4
When a person living with HIV is on effective medication with an undetectable viral load, they cannot pass on HIV to their sexual partners.5,6 This is widely known as Undetectable = Untransmittable (U=U).
With effective HIV treatment and the support of your healthcare team, most people living with HIV can reach an undetectable viral load. But remember, even once you’ve achieved an undetectable viral load, you still need to keep taking your medicine, attend regular check-ups with your healthcare team, follow safe-sex practices and avoid needle sharing.1
