“…NLVs have been implicated in 96% of the outbreaks of acute nonbacterial gastroenteritis in the US documented by the Centers for Disease Control and Prevention (CDC) between 1996(Fankhauser et al, 1998. Additionally, NLVs are a major cause of acute nonbacterial gastroenteritis in children and adults worldwide (Bon et al, 1999;Parks et al, 1999;Taylor et al, 1996;Vinje et al, 1997). NLV outbreaks have been reported in communities, schools and day care centers, nursing homes, hospitals, recreational areas, cruise ships, military ships and bases (Fankhauser et al, 1998;Grohmann et al, 1991;McCarthy et al, 2000;Sharp et al, 1995).…”
