Abstract

Globally, surveillance systems showed an increasein norovirus activity in late 2012. Molecular datashared through the NoroNet network suggest thatthis increase is related to the emergence of a newnorovirus genotype II.4 variant, termed Sydney 2012.Healthcare institutions are advised to be prepared fora severe norovirus season.
