Examples

• The patient's high fever and rash were consistent with a period of acute viremia.

Advanced Usage

• Primary viremia: The initial spread of virus into the blood from the primary site of infection.
• Secondary viremia: A subsequent, often larger-scale, presence of virus in the blood following replication in major organs.
• The degree or level of viremia is often quantified (e.g., "high-titer viremia," "low-level viremia") as it can correlate with disease severity and transmissibility.
