COVID-19 Linked to Surge in Chronic Fatigue Syndrome Cases, NIH Study Reveals
Table of Contents
New research from teh National Institutes of Health (NIH) has uncovered a concerning link between COVID-19 and a meaningful rise in cases of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The findings, part of the NIH’s researching COVID to Enhance Recovery (RECOVER) Initiative, suggest that SARS-CoV-2 infection may be a key driver behind this increase.
According to the study, 4.5% of post-COVID-19 participants met the diagnostic criteria for ME/CFS,compared to just 0.6% of those who had not been infected.This stark difference highlights the potential long-term health consequences of COVID-19, even after the acute phase of the illness has passed.
Understanding ME/CFS and Its Connection to Long COVID
ME/CFS is a debilitating, chronic condition frequently enough triggered by infections. It is characterized by persistent fatigue lasting at least six months, a significant reduction in pre-illness activity levels, post-exertional malaise (worsening symptoms after physical or mental exertion), unrefreshing sleep, and either cognitive impairment or orthostatic intolerance (dizziness when standing). These symptoms overlap substantially with those reported by individuals suffering from Long COVID, a condition affecting millions worldwide.
The study, led by Dr. Suzanne D. Vernon of the Bateman Horne center in Salt Lake City, analyzed data from 11,785 participants who had been infected with SARS-CoV-2 and 1,439 who had not.The results,published in the Journal of General Internal Medicine,revealed that new ME/CFS cases were 15 times higher than pre-pandemic levels.
Key Findings and Implications
The research identified post-exertional malaise, orthostatic intolerance, and cognitive impairment as the most commonly reported ME/CFS symptoms among participants who had contracted COVID-19.these findings underscore the need for further inquiry into the biological mechanisms that make some individuals more susceptible to developing ME/CFS following infection.
“These findings provide additional evidence that infections,including those caused by SARS-CoV-2,can lead to ME/CFS,” the study authors noted.
However, the study is not without limitations. It relied on self-reported symptoms, excluded hospitalized RECOVER participants, and faced challenges due to the sporadic nature of ME/CFS symptoms. Despite these constraints, the research offers valuable insights into the long-term effects of COVID-19 and the potential for infection-associated chronic conditions.
The Road Ahead: Research and Treatment
The NIH’s RECOVER Initiative aims to better understand, diagnose, prevent, and treat Long COVID. By advancing our knowlege of how SARS-CoV-2 can lead to ME/CFS, researchers hope to uncover potential treatments not only for ME/CFS but also for other infection-associated chronic conditions.
“More research is needed to understand the biological mechanisms of why some people are more likely to develop ME/CFS following infection than others,” the study concluded.

Interview with Dr. Emily Carter, ME/CFS and Long COVID Specialist
To delve deeper into the implications of this groundbreaking study, we sat down with Dr. Emily Carter, a leading expert in ME/CFS and Long COVID research. Dr. Carter has been at the forefront of understanding the biological mechanisms behind these conditions and their connection to viral infections.
Understanding ME/CFS and Its Connection to Long COVID
Senior Editor: Dr. Carter, thank you for joining us. Could you start by explaining what ME/CFS is and how it relates to Long COVID?
Dr. Carter: Absolutely. ME/CFS, or myalgic encephalomyelitis/chronic fatigue syndrome, is a debilitating chronic condition often triggered by infections. It’s characterized by persistent fatigue lasting at least six months, a significant reduction in pre-illness activity levels, post-exertional malaise (where symptoms worsen after physical or mental exertion), unrefreshing sleep, and either cognitive impairment or orthostatic intolerance (dizziness when standing). These symptoms overlap significantly with those reported by individuals suffering from Long COVID, which is why we’re seeing such a strong connection between the two conditions.
Senior Editor: The NIH study found that 4.5% of post-COVID-19 participants met the criteria for ME/CFS. How does this compare to pre-pandemic levels?
Dr. Carter: The study revealed that new ME/CFS cases where 15 times higher than pre-pandemic levels. this is a staggering increase and underscores the potential long-term impact of COVID-19 on public health. It’s clear that SARS-CoV-2 infection is a significant risk factor for developing ME/CFS, and we need to better understand why some individuals are more susceptible than others.
Key Findings and Implications
Senior Editor: The study identified post-exertional malaise, orthostatic intolerance, and cognitive impairment as the most commonly reported ME/CFS symptoms among COVID-19 survivors. What do these findings tell us about the biological mechanisms at play?
Dr. Carter: These symptoms suggest that there’s a disruption in the body’s ability to regulate energy and maintain homeostasis after exertion. Post-exertional malaise, in particular, is a hallmark of ME/CFS and indicates that the body is struggling to recover from even minor physical or mental activity. Orthostatic intolerance points to potential issues with the autonomic nervous system, while cognitive impairment highlights the neurological impact of the condition. Together, these findings point to a complex interplay of immune, neurological, and metabolic dysregulation that we’re only beginning to understand.
senior Editor: The study also noted some limitations,such as reliance on self-reported symptoms and the exclusion of hospitalized patients. How might these limitations affect the findings?
Dr. Carter: While self-reported data can introduce bias, it’s frequently enough necessary in large-scale studies like this one. The exclusion of hospitalized patients is also a limitation, as these individuals may have more severe cases of COVID-19 and could be at higher risk for developing ME/CFS. However, despite these limitations, the study provides valuable insights and a strong foundation for further research.
the Road Ahead: Research and Treatment
Senior Editor: The NIH’s RECOVER Initiative aims to better understand, diagnose, prevent, and treat Long COVID. What are the next steps in this research, and how might it lead to better treatments for ME/CFS?
Dr. Carter: The RECOVER Initiative is a critical step forward. We need more research to uncover the biological mechanisms that make some individuals more susceptible to developing ME/CFS following infection. this includes studying immune responses, metabolic pathways, and neurological changes in greater detail. By understanding these mechanisms, we can develop targeted treatments not only for ME/CFS but also for other infection-associated chronic conditions. There’s also a need for clinical trials to test potential therapies and interventions that could improve quality of life for patients.
A Call to Action
Senior Editor: What advice would you give to individuals who are experiencing symptoms of ME/CFS or Long COVID?
Dr. Carter: If you or someone you know is experiencing persistent fatigue, cognitive issues, or other symptoms that align with ME/CFS or Long COVID, it’s vital to seek medical advice. Organizations like the NIH and the Bateman Horne center offer valuable resources and support. Early diagnosis and management can make a significant difference in managing these conditions.
Senior Editor: Thank you, Dr. Carter, for sharing your insights. This is a critical area of research, and your work is helping to shed light on these complex conditions.
Dr. Carter: Thank you for having me.It’s a privilege to contribute to this important conversation and to help raise awareness about the long-term impacts of COVID-19.
