Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by the SARS-associated coronavirus (SARS-CoV). It was first reported in Asia in 2003. The SARS outbreak of 2003 made it a disease to watch. While it seems SARS has subsided in its aggression, with no known cases reported worldwide since 2004, it is always best to stay informed and prepared.
