The etiological agent is a novel coronavirus (CoV), designated as SARS-CoV, which emerged from an animal reservoir during the winter 2002–2003 when it infected over 8000 humans worldwide. It emerged again the next winter and since then, no SARS outbreak has been recorded (Chen and Subbarao 2007). Yet, a serious possibility of reemergence of SARS-CoV or of the introduction of other related viruses from an animal reservoir remains."}
