TL;DR: Data from ten European countries show a striking increase and unusual seasonal pattern of norovirus gastroenteritis in 2002 that occurred concurrently with the emergence of a novel genetic variant, raising questions about the biological properties of the variant and the mechanisms for its rapid dissemination.

TL;DR: The ability of the network to identify strains circulating with an incidence of ⩾1% allowed the identification of possible emerging strains such as G8 and G12 since the beginning of the study; analysis of recent data indicates their increased incidence.

TL;DR: The consecutive emergence of new GII.4 variants is highly indicative of immune-driven selection, and their predominance in health care settings suggests properties that facilitate transmission in settings with a high concentration of people such as higher virus loads in excreta or a higher incidence of vomiting.

TL;DR: Investigations showed that the outbreaks of gastroenteritis in Denmark in mid January 2010 were caused by norovirus of several genotypes and by enterotoxigenic Escherichia coli.

TL;DR: The single most important cause of diarrhea was rotavirus, which points toward the need for a childhood vaccine for this pathogen, but norov virus, adenovirus, and sapovirus were also major etiologies.
