Viremia is a condition where viruses enter the bloodstream. It is related to bacteremia, a condition where bacteria enter the bloodstream, and septicemia.

Active viremia refers to the capability of the virus to replicate in blood.
There are two types of viremia:
Primary viremia, which is the initial spread of virus in the blood.
Secondary viremia, where the primary viremia has resulted in infection of additional tissues, in which the virus has replicated and once more entered the circulation.
Thirteen patients had undetectable viremia at their first available viral load measurement and a shorter delay between seroconversion and undetectable viremia (median delay, 12.3 months), compared with 23 seroconverters who had a detectable viral load before undetectable viremia was achieved (median delay, 39.0 months).
A strict definition considered the duration of undetectable viremia to be only the first period of undetectable viremia (definition 1), and a broader definition considered the duration of undetectable viremia to be the time from the beginning of the first period to the end of the last period of undetectable viremia (definition 2).
Nevertheless, use of low-level viremia to interpret the impact of treatments in nonrandomized studies of patients with HIV seroconversion (i.e., HIV seroconverters) is problematic.
