Viral load refers to the amount of HIV in the blood. An undetectable viral load is when the amount of HIV in the blood is so low that it canât be measured. Antiretroviral therapy (ART) reduces viral load, ideally to an undetectable level, when taken consistently and correctly.
1 Sexually transmitted diseases (STDs) increase viral load in genital fluids. 2  This means that an HIV-positive person with an STD may be able to transmit HIV to sexual partners even if the blood viral load is undetectable.
