Clinical Scorecard: COVID-19 May Reactivate Dormant Viruses

At a Glance

Key Highlights

• Nearly half of hospitalized COVID-19 patients had detectable reactivation of chronic viruses.
• Epstein-Barr virus reactivated early in 24% of patients during the first week.
• Cytomegalovirus and human alphaherpesvirus 1 were detected later in the illness.
• Viral transcript detection correlated with greater COVID-19 severity.
• No association found between acute viral detection and long COVID symptom groups.

Guideline-Based Recommendations

Diagnosis

• RNA sequencing can identify reactivated viral transcripts in patients.

Management

• Routine monitoring of viral reactivation is not established for improving patient care.

Monitoring & Follow-up

• Quantitative polymerase chain reaction assays are available for several herpesviruses and Anelloviridae.

Risks

• Cytomegalovirus and herpesvirus presence associated with one-year mortality in critically ill patients.

Patient & Prescribing Data

Unvaccinated hospitalized patients with COVID-19.

Viral reactivation may reflect disease severity but does not establish causation.

Clinical Best Practices

• Consider monitoring for viral reactivation in hospitalized COVID-19 patients.
• Utilize RNA sequencing for comprehensive viral detection.
