Journal ArticleDOI
Transmission of H7N7 avian influenza A virus to human beings during a large outbreak in commercial poultry farms in the Netherlands
Marion Koopmans,Berry Wilbrink,Marina Conyn,G Natrop,Hans van der Nat,Harry Vennema,Adam Meijer,Jim E. van Steenbergen,Ron A. M. Fouchier,Albert D. M. E. Osterhaus,A Bosman +10 more
TL;DR: An unexpectedly high number of transmissions of avian influenza A virus subtype H7N7 to people directly involved in handling infected poultry, and evidence for person-to-person transmission are noted.
Journal ArticleDOI
An automated genotyping tool for enteroviruses and noroviruses
Annelies Kroneman,Harry Vennema,K. Deforche,Harrie van der Avoort,Silvia Peñaranda,M.S. Oberste,Jan Vinjé,Matty Koopmans +7 more
TL;DR: The online typing-tools reliably assign genotypes for enterovirus type or norovirus genotype and/or variant, with profile alignment, construction of phylogenetic trees and bootstrap validation makes these tools robust to ongoing evolution.
Journal ArticleDOI
Norovirus Illness Is a Global Problem: Emergence and Spread of Norovirus GII.4 Variants, 2001–2007
J. Joukje Siebenga,Harry Vennema,Du-Ping Zheng,Jan Vinjé,Bonita E. Lee,Xiao-Li Pang,Eric C.M. Ho,Wilina Lim,Avinash Choudekar,Shobha Broor,Tamar Halperin,Nassar B. G. Rasool,Joanne Hewitt,Gail E. Greening,Miao Jin,Zhao-jun Duan,Yalda Lucero,Miguel O'Ryan,Marina Hoehne,Eckart Schreier,Rodney M. Ratcliff,Peter A. White,Nobuhiro Iritani,Gábor Reuter,Marion Koopmans +24 more
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.
Journal ArticleDOI
Increase in viral gastroenteritis outbreaks in Europe and epidemic spread of new norovirus variant
Ben Lopman,Harry Vennema,Evelyne Kohli,Pierre Pothier,Alicia Sanchez,Anabel Negredo,Javier Buesa,Eckart Schreier,Mark Reacher,David R. Brown,Jim Gray,Miren Iturriza,Christopher Gallimore,Blenda Böttiger,Kjell Olof Hedlund,Maria Torvén,Carl Henrik von Bonsdorff,Leena Maunula,Mateja Poljšak-Prijatelj,Janet Zimšek,Gábor Reuter,György Szücs,Béla Melegh,Lennart Svennson,Yvonne van Duijnhoven,Marion Koopmans +25 more
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.
Journal ArticleDOI
Proposal for a unified norovirus nomenclature and genotyping.
Annelies Kroneman,Everardo Vega,Harry Vennema,Jan Vinjé,Peter A. White,Grant S. Hansman,Kim Y. Green,Kim Y. Green,Vito Martella,Kazuhiko Katayama,Marion Koopmans +10 more
TL;DR: It is demonstrated that the pairwise distance cutoff method can no longer be used and a phylogenetic approach to classify noroviruses is outlined and a dual nomenclature using both ORF1 and VP1 sequences is proposed, as recombination is common and recognizing recombinant viruses may be relevant.
