Emerg Infect Dis. 2013 Aug;19(8):1317-20. doi: 10.3201/eid1908.130445.

Abstract

We report an increase in the proportion of genotype GI.6 norovirus outbreaks in the United States from 1.4% in 2010 to 7.7% in 2012 (p<0.001). Compared with non-GI.6 outbreaks, GI.6 outbreaks were characterized by summer seasonality, foodborne transmission, and non-health care settings.

Keywords: GI.6 genotype; Norovirus; United States; gastroenteritis; outbreak; surveillance; viruses.
