Hidden Viruses Wake Up After COVID: New Study Links One to Long COVID

Published: 16 August 2026 · 1 min read

What Happened

A major U.S. study of over 1,100 hospitalized COVID-19 patients found that the infection can reactivate dormant viruses such as Epstein-Barr, cytomegalovirus, and herpes viruses. Researchers identified 11 reactivated viruses within 40 days of hospital admission.

Key Takeaways

Researchers found that reactivation of the little-understood Anelloviridae virus family was strongly associated with long COVID and long-term physical disability, potentially offering an important clue to why some patients experience prolonged symptoms after recovery.
