People living with HIV who are on anti-retroviral treatment and maintain an undetectable viral load (UVL) for at least six months do not sexually transmit HIV.
An undetectable viral load is when the amount of HIV in a person’s blood (viral load) is no longer able to be detected by a standard viral load test for HIV.
If a person living with HIV has been taking medication consistently, and has been able able to obtain and sustain an undetectable viral load (UVL) for six months, there is virtually no chance they will pass HIV on to someone else if they have sex without a condom.
Once someone’s viral load reaches ‘undetectable’ it does not mean it will stay that way for ever. A person’s viral load can go up and down depending on individual circumstances.
Some people living with HIV may never be able to obtain an undetectable viral load, so it’s important not to assume that they can.
