Abstract
Objective. To study the epidemiologic, clinical, laboratory, and radiologic features, prognostic indicators, and short-term to medium-term outcomes for children with severe acute respiratory syndrome (SARS) and to validate the performance characteristics of a clinical case definition, calculated with respect to SARS-associated coronavirus (SARS-CoV) seroconversion.Methods. Children 12 years was associated with oxygen requirements. Sore throat, high neutrophil count at presentation, and peak neutrophilia were independent factors predicting severe illness. The clinical case definition demonstrated good sensitivity, specificity, and positive and negative predictive values (97.8%, 92.7%, 88%, and 98.7%, respectively) for diagnostic accuracy.Conclusions. Children are susceptible to SARS-CoV infection. Teenagers resemble adults with respect to disease progression and may develop severe illness. The short-term to medium-term outcomes are good. Sore throat and initial and peak neutrophilia seem to be predictors of severe illness. Our clinical case definition performed well in the epidemic.
