Indications for Worldwide Increased Norovirus Activity Associated With Emergence of a New Variant of Genotype II.4, Late 2012

Euro Surveill. 2013 Jan 3;18(1):8-9.

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.
