viral load
Pathogen concentration measured
Viral load is the quantity of virus present in a person's blood or other bodily fluid, typically measured in copies per milliliter.
The term became widely known during the HIV/AIDS epidemic, where tracking viral load helps gauge disease progression and treatment effectiveness.
An undetectable viral load means medication has suppressed the virus below measurable levels.
