Laboratory-Acquired Severe Acute Respiratory Syndrome

Abstract
The outbreak of severe acute respiratory syndrome (SARS) in Singapore ended in late May 2003.1 The Centers for Disease Control and Prevention (CDC) removed its travel alerts for Toronto, Hong Kong, China, and Taiwan shortly thereafter.2 We report the first case of SARS to occur in Singapore after the initial worldwide outbreak ended. Our report documents the transmission of SARS in a laboratory setting.
