Abstract
BACKGROUND: COVID-19 is a new disease, so we don't know what comes next. Since information on delayed symptoms is limited, this study was conducted to assess the frequency of delayed symptoms in patients with COVID-19.

Two hundred patients hospitalized for COVID-19 and were discharged were assessed for delayed symptoms 6 wk after discharge.

On admission to hospital, patients reported a mean of 5.63±2.88 symptoms per patient, range from 1 to 14 symptoms. Dyspnea was seen in 119 (59.5%) 0f them as the most frequent symptom. Then weakness, myalgia, and shivering were reported with a frequency of 111 (55.5%), 107 (53.5%), and 103 (51.5%), respectively. Six weeks after discharge reassessment was done.
