Outbreaks of acute gastroenteritis associated with a re-emerging GII.P16-GII.2 norovirus in the spring of 2017 in Jiangsu, China.

ABSTRACT: A total of 64 acute gastroenteritis outbreaks with 2,953 patients starting in December of 2016 and occurring mostly in the late spring of 2017 were reported in Jiangsu, China. A recombinant GII.P16-GII.2 norovirus variant was associated with 47 outbreaks (73.4%) for the gastroenteritis epidemic, predominantly occurring in February and March of 2017. Sequence analysis of the RNA-dependent RNA polymerase (RdRp) and capsid protein of the viral isolates from these outbreaks confirmed that this GII.P16-GII.2 strain was the GII.P16-GII.2 variant with the intergenotypic recombination, identified in Taiwan, Hong Kong, and other cities in China in 2016. This GII.P16-GII.2 recombinant variant appeared to a re-emerging strain, firstly identified in 2011-2012 from Japan and USA but might be independen
