What is U=U?
U=U is an abbreviation for Undetectable = Untransmittable. It means that someone with an undetectable HIV viral load on ARVs cannot transmit HIV, even without using condoms.
A person living with HIV is considered to have an ‘undetectable’ viral load when antiretroviral (ARV) treatment has brought the level of virus in their body to such low levels that blood tests cannot detect it.
In other words, someone who is HIV positive whose viral load is ‘undetectable’ because of treatment cannot transmit the virus during sex.
U=U is also an international campaign to raise awareness about the benefits of ARVs.
