In this study of more than 6500 emergency department patients, symptoms consistent with Long COVID are reported by 38.9% of SARS-CoV-2 test-positive and 20.7% of test-negative patients three months after their visit. A documented SARS-CoV-2 infection increased the risk fourfold of reporting Long COVID symptoms.
