When a person living with HIV takes HIV treatment (a combination of medications known as
Anti-Retroviral Therapy or
ART), over time, it can reduce the amount of HIV in their body (viral load) to a level so low, that it can’t be detected in a blood test (this is called an
undetectable viral load or viral suppression).
When a person’s viral load is undetectable, it is impossible to pass on HIV through sex.
Pretty cool, isn’t it? This
scientifically proven fact is known as
Undetectable = Untransmittable, or
U=U. This normally happens when a person living with HIV has been working with a doctor to look after their health. People living with HIV who have access to treatment and care may refer to themselves as being undetectable and having an undetectable
viral load. This does not mean that they are cured of HIV.
HIV treatment prevents the virus from creating more copies of itself within the body. Taking HIV treatment regularly suppresses the viral load in most people. This process can take up to as little as one month, but most people who are able to stick to their medication routine achieve viral suppression within the first six months of being on treatment.
