U = U
When HIV is undetectable, it is untransmittable.
When people living with HIV take antiretroviral therapy as prescribed, their viral load - the amount of HIV in their blood - becomes so low that it is undetectable by a standard blood test.
It has been scientifically proven that people living with HIV on effective treatment and who have maintained an undetectable viral load for at least six months cannot transmit HIV to their sex partners. Most people living with HIV can achieve an undetectable viral load within six months of starting antiretroviral therapy.
Sensitizing the public to the "undetectable equals untransmittable" or "U=U" message is critical in destigmatizing HIV and reducing discrimination against people living with HIV.
