Study Population
Over a five months period, 29 pediatric subjects presented to CHOP Pulmonary Clinic for evaluation of persistent symptoms six weeks or more after COVID-19 infection (Table 1 ). Of subjects seen for COVID- related complaints, 14% had previously been followed in CHOP Pulmonary Clinic for other concerns prior to their acute COVID-19 infection. The mean age at presentation was 13.1 years (range: 4-19 years). Females (58.6%) and non-whites (55.25%) made up the majority of the patients seen. Many subjects were overweight or obese with a BMI above the 85th percentile (62.1%). Baseline atopy, defined as presence of asthma, eczema and/or allergic rhinitis, was present in 65.5% of subjects. Of the eleven subjects with asthma, 55% had mild asthma, 36% had moderate asthma, and 9% had severe asthma. Eight subjects with asthma were previously prescribed a daily inhaled corticosteroid. Most subjects (96.6%) reported engagement in regular physical activity prior to acute COVID-19 infection.
