A Study on Clinical Parameters of Patients with Severe Acute Respiratory Syndrome and Fever-clinic Patients

Objective To investigate clinical features of patients with severe acut respiratory syndrome (SARS) and fever-clinic patients in SARS prevalence days. Methods Clinical data of 45 SARS patients, 150 medical observation patients and 1200 home observation patients from fever-clinic were analyzed retrospectively. Results All the 45 SARS patients had the medical history of close contact with SARS, and their body temperatures were higher than the fever-clinic patients' ones. Leucopenia and lymphopenia in SARS patients were more common than those in the home observation patients, but were similar with those in the medical observation patients. All the SARS patients' chest radiographs showed large area of interstitial infiltration or shadows, and 46 7% patients developed rapidly in a short time. Conlusion Epidemic history and chest radiograph findings may be the major evidences to diagnose SARS, while the fever symptom and blood routine examination may be helpful to screen SARS.
