A landmark new study published in the journal Nature has given the medical community and the millions of Americans living with long COVID a greater understanding of the virus and its capabilities. Researchers at Boston Children's Hospital and 14 collaborating institutions analyzed more than 1,100 hospitalized COVID-19 patients and found that severe COVID-19 infections can reactivate dormant viruses that have been quietly hiding in the human body, sometimes for decades. For long COVID patients who have been unable to return to work, this discovery carries real implications for understanding why recovery has remained out of reach.
What to Know About This Topic:
- Researchers studying more than 1,100 hospitalized COVID-19 patients found that nearly half experienced the reactivation of one or more dormant viruses during their illness, including Epstein-Barr virus, cytomegalovirus, herpes simplex virus 1, and Anelloviridae, a virus family carried by roughly 90% of adults that has traditionally been considered harmless.
- Reactivation of Anelloviridae was specifically linked to long COVID and lasting physical disability, offering a new biological explanation for why many long COVID patients remain unable to recover and return to work long after their initial infection.
- For workers whose disability insurance claims involve long COVID, this growing body of medical evidence adds documented complexity to their condition.
Researchers Link COVID-19 to Dormant Viruses
Most people carry multiple dormant viruses in their bodies without ever knowing it. Epstein-Barr virus, which is the virus responsible for mononucleosis, for example, remains in the body after infection and is present in the vast majority of adults. Cytomegalovirus, herpes simplex virus, and an entire family of viruses known as Anelloviridae follow the same pattern, taking up long-term residence in the body and causing no noticeable symptoms in most people under normal circumstances. For years, scientists largely believed these viruses stayed dormant because the immune system kept them in check, and that significant immune suppression was required for them to reactivate.
The new research from Boston Children's Hospital challenges that assumption. According to the study's findings, viral reactivation occurred frequently even in patients who appeared to have functioning immune systems, suggesting that the severe systemic inflammation caused by COVID-19, rather than immune suppression alone, is enough to wake these viruses back up. 11 different dormant viruses were detected in patients within the first 40 days of hospital admission, with different viruses following their own distinct timelines of reactivation and each producing its own set of immune and metabolic consequences.
The finding that drew the most attention from the long COVID research community involved Anelloviridae. Unlike the better-known herpes family viruses, Anelloviridae has historically been considered so benign that it received little scientific attention. That may be changing. In this study, its reactivation was prominently associated with long-term physical disability and long COVID, raising the possibility that a virus most people carry without incident could, once awakened by a severe COVID-19 infection, contribute to the kind of prolonged, disabling illness that has defined the long COVID experience for millions of patients. As researchers noted, this finding could create urgency around better understanding these viruses and developing new treatments.

Dormant Virus Reactivation Compounds Long COVID
Long COVID already presents a complex and often unpredictable clinical picture. Patients experience a wide range of debilitating and persistent symptoms, including profound fatigue, cognitive impairment commonly described as brain fog, post-exertional malaise, cardiovascular complications, neurological symptoms, sleep disorders, and more. Many long COVID patients describe a cycle in which they begin to feel marginally better, attempt to resume normal activities, and then experience a significant setback that sends them back to square one. For workers, that cycle makes consistent, reliable occupational functioning effectively impossible.
What this new research suggests is that for some long COVID patients, the body is not simply struggling to recover from a single viral infection. It may be managing the simultaneous effects of a reactivated Epstein-Barr infection, a reactivated cytomegalovirus infection, or an awakened Anelloviridae virus, each producing its own inflammatory response, its own metabolic demands, and its own set of symptoms layered on top of the long COVID baseline. The practical result is a body under assault from multiple directions at once, with an immune system stretched across competing threats and a recovery timeline that becomes increasingly difficult to predict or define. For patients who were already struggling to return to work, the addition of reactivated viral activity provides a new and medically documented explanation for why their recovery has not followed a predictable path.
What This Research Means for Long COVID Disability Insurance Claims
Disability insurance carriers don’t always treat long COVID claims with the seriousness the condition deserves. Because long COVID does not always produce clear abnormalities on standard imaging or routine laboratory panels, insurers have frequently questioned whether claimants are truly disabled, arguing that the absence of obvious objective findings means the absence of an impairment. That line of reasoning has been used to deny and terminate the benefits of long COVID patients whose conditions are real, severe, and extensively documented by their treating providers.
Research like this new Nature study provides an additional layer of objective, scientifically grounded explanation for why long COVID patients remain unable to work. A claim that might otherwise be characterized by an insurer as poorly documented or functionally inconsistent can now be supported by a growing body of peer-reviewed research showing that the biological mechanisms driving long COVID disability are real, measurable, and increasingly well understood. Viral reactivation adds medical complexity to an already complex condition, and that complexity should be reflected in any related disability claim.
