Objectives: To determine the clinical presentation, findings, and outcomes of older adults (> 60) with severe acute respiratory syndrome (SARS) and compare these with a control group of younger patients (≤60). Design: Retrospective cohort study. Setting: A community‐based, acute hospital in Hong Kong. Participants: All adult inpatients with a clinical diagnosis of SARS. Measurements: Clinical presentations, investigations, treatment, and 30‐ and 150‐day mortality. Results: There were 52 young and 25 older patients with a mean age±standard deviation of 39.5±11.7 and 72.1±7.2, respectively. Fever, chills, and diarrhea were more common in younger patients, whereas decrease in appetite and general condition occurred only in older patients. The prevalence of positive reverse‐transcriptase polymerase chain reaction for SARS‐associated coronavirus (SARS‐CoV) in nasopharyngeal secretions and stool samples was similar in the two groups. The prevalence of positive serological tests for SARS‐CoV was significantly lower in older patients (42% vs 92%, P |
