This study looked at 416 children who had COVID-19 and received chest CT scans. About 23% of the children who were followed up developed Long COVID—experiencing symptoms like lasting cough, tiredness, brain fog, and worsening after physical activity. The researchers found that children with certain patterns on their chest CT scans (increased blood vessel markings) and younger children were more likely to develop Long COVID.
This study provides epidemiological evidence that a substantial proportion of children develop persistent symptoms after COVID-19, with findings that mirror key ME/CFS features including post-exertional malaise and brain fog. Understanding which imaging biomarkers might predict Long COVID progression in children could inform early identification strategies and mechanistic research relevant to ME/CFS pathophysiology.
This study does not establish that chest CT abnormalities directly cause Long COVID; the authors themselves noted no significant correlation despite identifying vascular markings as a predictor in a decision tree model. It does not clarify the biological mechanisms underlying Long COVID, nor does it prove that imaging findings are causally linked rather than merely associated with disease development. The findings are specific to pediatric populations in two Chinese centers and may not generalize to other age groups or geographic regions.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
