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.
However, patients infected with hep C are usually not undetectable and can also transmit hepatitis C sexually. Thus, unsafe sex, although protective for HIV if the partners are undetectable, does not protect against hepatitis C or syphilis.
