Severity of lung abnormalities quantified on chest radiographs correlates with clinical and laboratory parameters.

The initial extent of radiographic opacification may be useful for prognostic prediction. Radiographic progression correlates well with that of important clinical and laboratory parameters and may be used as an objective prognostic indicator early in SARS.

There are significant relationships among radiographic parameters, oxygen supplementation, and treatment response, and these relationships appear to be clinically useful in the treatment of SARS.

Severe acute respiratory syndrome (SARS) is a highly contagious and predominantly pneumonic illness caused by a novel coronavirus now commonly known as SARS-CoV. This article describes the key diagnostic clinical features, radiologic features, and investigation profiles of affected patients. We summarize our understanding from anecdotal experience and limited published data on the use of antiviral and corticosteroid therapy in the management of this highly contagious disease.

This study provided a reliable baseline estimate of the hospitalization burden of pneumococcal pneumonia in Hong Kong children before the advent of universal conjugate pneumococcal vaccination.
