What does U=U mean?
U=U stands for Undetectable = Untransmittable. This means that if a HIV positive person’s viral load (the amount of virus in the blood) is undetectable, it is impossible to transmit HIV to sexual partners.
How do I get to undetectable?
Anti-retroviral therapy can decrease the amount of HIV in the blood to be too low to measure. When the load cannot be measured, you are undetectable. This is usually at the fewer than 50 copies of HIV per milliliter of blood (<50 copies/mL) point. When your viral load is under 200 copies, the chance of transmitting HIV sexually is virtually zero.
How long does it take to become undetectable?
It may take 1 to 6 months to become undetectable. Once you are undetectable, it can take another 6 months to maintain an undetectable status. After the 6 months of maintenance, there is effectively no risk of transmitting HIV to a sexual partner.
It is extremely important that you take your medication as prescribed and do not fall out of your treatment schedule because this could cause the virus levels in your blood to rebound and become detectable and transmittable.
What about intravenous drug use?
U=U does NOT prevent transmission when sharing needles. U=U has only been found to be effective in stopping sexual transmission.
