COVID can wake up a slew of dormant viruses inside you

TL;DR - A Nature news item reporting on a study that found SARS-CoV-2 infection can reactivate dormant viruses already resident in the body, with reactivation of normally benign anelloviruses appearing linked to long COVID. It matters as a possible biological mechanism and biomarker route for a condition that has lacked clear diagnostics.

• Core claim: COVID infection appears to "wake up" a range of latent/persistent viruses harbored in humans, rather than causing harm only through SARS-CoV-2 itself.
• Anelloviruses — typically harmless components of the human virome and often used as informal markers of immune status — are singled out as the strongest signal.
• The association reported is with developing long COVID, suggesting virome disruption or immune dysregulation as a candidate contributor.
• Content is thin (news blurb only): no cohort size, study design, effect sizes, or causal evidence are given here, so the link should be read as correlational pending the underlying paper.
