“…Two of these HCoV strains, designated OC43 and 229E, were detected in individuals with common colds, and occasionally in young children, elderly persons, immunocompromised individuals, and military personnel with lower respiratory tract infection (LRI) [Chany et al, 1982; Falsey et al, 2002; Folz and Elkordy, 1999; Gagneur et al, 2002; McIntosh et al, 1974; Monto, 1974; Riski and Hovi, 1980; Sizun et al, 1995; Sizun et al, 1994; Wenzel et al, 1974]. Recently, three new HCoV strains have been identified using both molecular and traditional culture methods: severe acute respiratory syndrome coronavirus (SARS-CoV) [Drosten et al, 2003], human coronavirus Netherlands (HCoV-NL63) [Fouchier et al, 2004; van der Hoek et al, 2004], and human coronavirus Hong Kong (CoV-HKU1) [Woo et al, 2005].…”
