Key result
Recombinant norovirus GII.P16-GII.2 accounts for ~79% of acute gastroenteritis outbreaks in China.
Observational (n=313)
Yes
The GII.P16-GII.2 recombinant norovirus strain emerged as a predominant cause of outbreaks in China in late 2016, potentially replacing GII.4 viruses.
May signal need for targeted norovirus surveillance; leaves open global predominance and vaccine implications.
During October-December 2016, the number of norovirus outbreaks in China increased sharply from the same period during the previous 4 years. We identified a recombinant norovirus strain, GII.P16-GII.2, as the cause of 44 (79%) of the 56 outbreaks, signaling that this strain could replace the predominant GII.4 viruses.

Ao et al. (2017) conducted an observational in Norovirus-associated acute gastroenteritis (n=313). Norovirus GII.P16-GII.2 strain was evaluated on Proportion of norovirus outbreaks caused by the GII.P16-GII.2 strain during late 2016. A recombinant norovirus strain, GII.P16-GII.2, emerged as the predominant cause of acute gastroenteritis in China in late 2016, accounting for 79% of the 56 outbreaks during that period.
