Clinical definition of the HIV reservoir. Untreated HIV infection is characterised by high levels of viral replication that can be measured in the plasma of HIV-infected individuals. ART reduces viral replication to undetectable levels by standard viral load measurements. When ART is interrupted, HIV replication resumes, revealing that HIV persisted in cellular and anatomical ‘reservoirs’ during ART and that these reservoirs can re-ignite infection.
