TL;DR: Establishing a global NoV network by which data on strains with the potential to cause pandemics can be rapidly exchanged may lead to improved prevention and intervention strategies, and show notable differences in geographic prevalence.

Abstract: Background Noroviruses (NoVs) are the most common cause of viral gastroenteritis Their high incidence and importance in health care facilities result in a great impact on public health Studies from around the world describing increasing prevalence have been difficult to compare because of differing nomenclatures for variants of the dominant genotype, GII4 We studied the global patterns of GII4 epidemiology in relation to its genetic diversity Methods Data from NoV outbreaks with dates of onset from January 2001 through March 2007 were collected from 15 institutions on 5 continents Partial genome sequences (n = 775) were collected, allowing phylogenetic comparison of data from different countries Results The 15 institutions reported 3098 GII4 outbreaks, 62% of all reported NoV outbreaks Eight GII4 variants were identified Four had a global distribution-the 1996, 2002, 2004, and 2006b variants The 2003Asia and 2006a variants caused epidemics, but they were geographically limited Finally, the 2001 Japan and 2001Henry variants were found across the world but at low frequencies Conclusions NoV epidemics resulted from the global spread of GII4 strains that evolved under the influence of population immunity Lineages show notable (and currently unexplained) differences in geographic prevalence Establishing a global NoV network by which data on strains with the potential to cause pandemics can be rapidly exchanged may lead to improved prevention and intervention strategies

Strain-Specific Virolysis Patterns of Human Noroviruses in Response to Alcohols
Geun Woo Park,Nikail Collins,Leslie Barclay,Liya Hu,B. V. Venkataram Prasad,Benjamin A. Lopman,Jan Vinjé +6 more
TL;DR: Alcohol susceptibility patterns between different norovirus genotypes vary widely and that virolysis data for a single strain or genotype are not representative for all noroviruses are demonstrated.
Antigenic Relatedness of Norovirus GII.4 Variants Determined by Human Challenge Sera.
Ying-Chun Dai,Xu-Fu Zhang,Ming Xia,Ming Tan,Christina Quigley,Wen Lei,Hao Fang,Weiming Zhong,Bonita E. Lee,Xiao-Li Pang,Jun Nie,Xi Jiang +11 more
TL;DR: The overall abilities of G.II.4 NoVs to bind to the A/B/H HBGAs were maintained while their binding affinities to individual ABH antigens varied, highlighting the importance of human HBGas in NoV evolution and how conserved antigenic types impact vaccine development against GII. 4 variants.

Jones Anderson Monteiro Siqueira,Edivaldo Costa Sousa Júnior,Alexandre da Costa Linhares,Yvone Benchimol Gabbay +3 more
TL;DR: The present report documents the importance of NoV as a cause of childhood infection during a longitudinal study conducted more than 30 years ago, in which 20 children were included from birth to 3 years of age.

Noroviruses in oysters from local markets and oyster farms in southern Thailand.
Leera Kittigul,Kannika Pombubpa,Suntharee Sukonthalux,Tippawan Rattanatham,Fuangfa Utrarachkij +4 more
TL;DR: Findings indicate that NoV contamination in oysters obtained from both markets and oyster farms might pose a potential risk of acute gastroenteritis associated with raw oyster consumption.

A simple, fast, and accurate algorithm to estimate large phylogenies by maximum likelihood.
Stéphane Guindon,Olivier Gascuel +1 more
TL;DR: This work has used extensive and realistic computer simulations to show that the topological accuracy of this new method is at least as high as that of the existing maximum-likelihood programs and much higher than the performance of distance-based and parsimony approaches.

TL;DR: Overall, foodborne diseases appear to cause more illnesses but fewer deaths than previously estimated.
Food-related illness and death in the United States.
TL;DR: The results of this study are consistent with those of previous studies in the United States, South America, Spain, and Mexico, and although in countries like Chile, disk diffusion is practical and reliable for most susceptibility testing, detecting low-level vancomycin resistance in enterocci is difficult without supplementary testing.

The global burden of diarrhoeal disease, as estimated from studies published between 1992 and 2000
TL;DR: Current estimates of the global burden of disease for diarrhoea are reported and compared with previous estimates made using data collected in 1954-79 and 1980-89, finding that the total morbidity component of the disease burden is greater than previously.
Norwalk Virus: How Infectious Is It?
Peter Teunis,Christine L. Moe,Pengbo Liu,Sara E. Miller,Lisa C. Lindesmith,Ralph S. Baric,Jacques Le Pendu,Rebecca L. Calderon +7 more
TL;DR: A new variant of the hit theory model of microbial infection was developed to estimate the variation in Norwalk virus infectivity, as well as the degree of virus aggregation, consistent with independent (electron microscopic) observations.
