We analyzed data from reported outbreaks of norovirus (NoV)-caused gastroenteritis from 13 European countries (July 2001 to July 2006) for trends in time and indications of different epidemiology of genotypes and variants. Of the 13 countries participating in this surveillance network, 11 were capable of collecting integrated epidemiological and virological surveillance data and 10 countries reported outbreaks throughout the entire period. Large differences in the numbers and rates of reported outbreaks per country were observed, reflecting the differences in the focus and coverage of national surveillance systems. GII.4 strains predominated throughout the 5-year surveillance period, but the proportion of outbreaks associated with GII.4 rose remarkably during years in which NoV activity was particularly high. Spring and summer peaks indicated the emergence of genetically distinct variants within GII.4 across Europe and were followed by increased NoV activity during the 2002-2003 and 2004-2005 winter seasons. GII.4 viruses predominated in health care settings and in person-to-person transmission. The consecutive emergence of new GII.4 variants is highly indicative of immune-driven selection. 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. Understanding the mechanisms driving the changes in epidemiology and clinical impact of these rapidly evolving RNA viruses is essential to design effective intervention and prevention measures.

Data quality of 5 years of central norovirus outbreak reporting in the European Network for food-borne viruses / Kroneman A in Journal of Public Health [J Public Health], Vol. 30, N° 1 (03/2008)

[article]  inJournal of Public Health [J Public Health] > Vol. 30, N° 1 (03/2008) . - 82-90 Titre : Data quality of 5 years of central norovirus outbreak reporting in the European Network for food-borne viruses Type de document : Article scientifique Auteur(s) : Kroneman A ; Harris J ; Vennema H ; Duizer E ; van Duynhoven Y ; Gray J ; Iturriza M ; Bottiger B ; Falkenhorst G ; Johnsen C ; von Bonsdorff CH ; Maunula L ; Kuusi M ; Pothier P ; Gallay A ; Schreier E ; Koch J ; Szucs G ; Reuter G ; Krisztalovics K ; Lynch M ; McKeown P ; Foley B ; Coughlan S ; Ruggeri FM ; Di Bartolo I ; Vainio K ; Isakbaeva E ; Poljsak Prijatelj M ; Hocevar Grom A ; Bosch A ; Buesa J ; Sanchez Fauquier A ; Hernandez Pezzi G ; Hedlund KO ; Koopmans M Appartenance auteur(s) InVS DMI Année de publication : 2008 Article en page(s) : 82-90 Langues : Anglais (eng) Mots-clés : Norovirus ; Epidémie ; Réseau surveillance ; Surveillance épidémiologique ; Europe Résumé : BACKGROUND: The food-borne viruses in Europe (FBVE) network database was established in 1999 to monitor trends in outbreaks of gastroenteritis due to noroviruses (NoVs), to identify major transmission routes of NoV infections within and between participating countries and to detect diffuse international food-borne outbreaks. METHODS: We reviewed the total of 9430 NoV outbreak reports from 13 countries with date of onset between 1 January 2002 and 1 January 2007 for representativeness, completeness and timeliness against these objectives. RESULTS: Rates of reporting ranged from a yearly average of 1.8 in 2003 to 11.6 in 2006. Completeness of reporting of an agreed minimum dataset improved over the years, both for epidemiological and virological data. For the 10 countries that provided integrated (epidemiological AND virological) reporting over the 5-year period, the completeness of the minimum dataset rose from 15% in 2003 to 48% in 2006. Two countries have not been able to combine both data types due to the structure of the national surveillance system (England and Wales and Germany). Timeliness of reporting (median days between the onset of an outbreak and the date of reporting to the FBVE database) differed greatly between countries, but gradually improved to 47 days in 2006. CONCLUSION: The outbreaks reported to the FBVE reflect the lack of standardization of surveillance systems across Europe, making direct comparison of data between countries difficult. However, trends in reported outbreaks per country, distribution of NoV genotypes, and detection of diffuse international outbreaks were used as background data in acute questions about NoV illness and the changing genotype distribution during the 5-year period, shown to be of added value. Integrated reporting is essential for these objectives, but could be limited to sentinel countries with surveillance systems that allow this integration. For successful intervention in case of diffuse international outbreaks, completeness and timeliness of reporting would need to be improved and expanded to countries that presently do not participate.

Epidémie d'infections à calicivirus associée à la consommation de framboises congelées / Ponka A in Eurosurveillance [Euro Surveill], Vol. 4, N° 6 (06/1999)

La plupart des malades avaient déjeuné à la cantine de leur société dont la cuisine centrale livre chaque jour 1200 à 1300 déjeuners aux cantines des 59 bureaux que compte cette société. L'aliment incriminé était un coulis de framboises congelées importées de pays d'Europe de l'Est, la culture de ces baies étant peu développée en Finlande. Les conclusions de cette enquête et les soupçons émis lors de plusieurs épidémies similaires survenues en Finlande ont poussé les autorités nationales chargées du contrôle alimentaire à émettre des recommandations provisoires, à savoir que les cuisines industrielles ne devraient plus servir de mets non chauffés préparés avec des baies congelées. Il est possible que les baies soient un véhicule de transmission de gastroentérites virales plus courant que nous le pensons. De nouvelles études épidémiologiques, associées à l'utilisation de nouvelles techniques de biologie moléculaire, permettront d'évaluer le rôle des baies dans la transmission des infections à SRSV (small round structured viruses) ou petits virus ronds auxquels appartiennent les calicivirus retrouvés dans les échantillons de selles prélevés sur les malades.
