The switch from a dormant to a lytic stateis known as reactivation, a process that can be triggered by other viral infections,physiologic stressors, and immunosuppression, though sometimes a trigger is not apparent.5 As our patient was intermittently compliant with antiretroviral therapy,worsening immunosuppression is likely the trigger for reactivation of parvovirus asher CD4 count was 82 cells/μL. This evidence concerns the gene CD4 and viral infectious disease.
