  • Greater Pathogenicity of Norovirus Strains in 2003? A Syndromic Approach

    Content Type: Abstract

    Although norovirus (NoV) is the most common cause of acute gastroenteritis (ewinter vomiting diseaseí), its contribution to mortality remains unknown and may be an unrecognized problem [1]. In Europe a genetic shift in circulating NoV strains was… read more

In Europe a genetic … suggests that a new NoV variant which arose in 2002/2003 may be associated with a greater risk of death than earlier …
  • Respiratory Syndrome in the Netherlands in Relation to Pathogen Activity

    Content Type: Abstract

    Syndromic surveillance may be suited for detection of emerging respiratory disease elevations that could pass undiagnosed. The syndromes under surveillance should then retrospectively reflect known respiratory pathogen activity. To validate this for… read more

  • Syndromic Surveillance for a Large Respiratory Disease Outbreak by Legionella in the Netherlands

    Content Type: Abstract

    To evaluate the added value of a syndromic surveillance system in detecting a large severe respiratory disease outbreak with a point-source we used the Legionnaires' disease (LD) outbreak of 1999 in the Netherlands as a case-study. We… read more

  • Understanding the Dynamics of Gastro-Intestinal Syndrome: General Practioner and Hospital Data vs Laboratory Surveillance

    Content Type: Abstract

    Objective Understanding the baseline dynamics of syndrome counts is essential for use in prospective syndromic surveillance. Therefore we studied to what extent the known seasonal dynamics of gastro-intestinal (GI… read more
    … several of the GI pathogens (R’s: below -0.68 and above 0.70) and the resulting modeling problems we eventually … Thus, the syndrome group as it is currently defined, may be of limited value for aberration detection, but, we … the low level of explained variance. In that case, it may be the traditional pathogen surveillance (based on the …
  • Validation of Data from Medical Registrations in The Netherlands for Syndromic Surveillance Use: Comparing Respiratory Syndromes with Laboratory Surveillance

    Content Type: Abstract

    Objective To study if syndromic surveillance would have an added value over existing surveillance systems, we retrospectively evaluated whether known trends in respiratory pathogens are reflected in medical registrations in the… read more
    … by influenza and RSV. We conclude that all 4 data sources may prove useful for prospective syndromic surveillance. I …
  • Syndromic Surveillance with Death Data: a Pilot Study in the Netherlands

    Content Type: Abstract

    Crude mortality could be valuable for infectious disease surveillance if available in a complete and timely fashion. Such data can be of used for detecting, and tracking the impact of unusual health events (e.g. pandemic… read more
    … surveillance data. The results show that mortality data may be suited for early warning purposes of higher than …
  • Syndromic Surveillance with Death Data: Is Crude Mortality Data Suitable for Real Time Surveillance?

    Content Type: Abstract

    Crude mortality could be valuable for infectious disease surveillance if available in a complete and timely fashion. Syndromic surveillance with weekly deaths has been demonstrated to be useful in France. Such data can be of use… read more

  • Syndromic Surveillance for Detection of Increased Morbidity and Mortality by Influenza

    Content Type: Abstract

    To evaluate whether a rise or shift in severe morbidity and mortality by influenza can be detected with syndromic surveillance.
    … during the influenza season 2003/2004, this deviance may indicate more severe consequences of influenza infection …
