Most patients (94.7%) reported several symptoms. Fatigue, post\u2010exertional malaise, dizziness, nausea, headache, and concentration difficulties were the most common. Seronegative children had a higher number of individual symptoms. School absence and drop\u2010out from leisure activities was substantial in both groups with higher numbers for the seronegative group. Self\u2010reported health was low in both groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Children attending a specialist paediatric long COVID clinic experienced multiple symptoms and poor self\u2010reported health.
