As well as, information on medical historical past, microbiological and scientific COVID-19 course, and affected person demographics have been obtained from digital medical information.
At the very least three-quarters 325/428 (76%) of sufferers reported at the very least one persistent symptom. The most typical reported signs have been shortness of breath (157/428; 37%) and power fatigue (156/428; 36%) adopted by sleep issues (68/428; 16%), visible issues (55/428; 13%), and mind fog (54/428; 13%).
