Eurosurveillance, 1996 to 2021: 25 years of public health impact

An outbreak of shigellosis was recently reported in Denmark associated with the consumption of imported baby corn from Thailand. We report a similar outbreak of shigellosis in Queensland, Australia that is possibly linked to the Danish outbreak through a common source in Thailand.

Respiratory virus activity is detected in Europe each winter, yet the precise timing and size of this activity is highly unpredictable. The impact of influenza infection and/or acute respiratory infection in European countries is continuously monitored through a variety of surveillance systems. All of these sources of information are used to assess the nature and extent of activity of influenza and other respiratory viruses, and to offer guidance on the prevention and control of morbidity and mortality due to influenza at a local, national and international level. The early warning system for a forthcoming influenza epidemic is mainly based on the use of a set of thresholds. In the Czech Republic, the acute respiratory infection (ARI) reporting system, with automated data processing, uses a statistical model for the early detection of unusual increased rates of the monitored indicators. The collected data consists of the number of ARI, the number of complications due to ARI and the population registered with the reporting general practitioners and paediatricians, all collected separately in five age groups. To improve the reporting system in the Czech Republic, clinical data on the weekly incidence of influenza-like illness (ILI) within the same population and the same age groups was started in January 2004. These data fit the European Commission’s recently adopted ILI case definition and allows a better comparison of data with other countries in Europe, in particular those participating in EISS (European Influenza Surveillance Scheme).

The number of isolates of Salmonella anatum from infants (aged 1 to 11 months) in England and Wales was higher than expected in November and December 1996 and early January. The Public Health Laboratory Service (PHLS) Laboratory of Enteric Pathogens (LEP)
