Every year, a winter outbreak of acute viral gastroenteritis (AVG) occurs in France, resulting in 1 to 1.5 million visits to primary care physicians. Clusters of cases occur in group settings, particularly in healthcare facilities where persistent environmental contamination facilitates the transmission of viruses, especially noroviruses. We present surveillance data on AGV for the 2006–2007 winter season in metropolitan France. Method. Surveillance of acute gastroenteritis in France is carried out by several complementary systems: the Sentinelles Network for cases presenting to general practitioners, a network of hospital emergency departments, reporting of nosocomial infections, mandatory reporting of collective foodborne illnesses, and the National Reference Center for Enteric Viruses. Results. According to data from the Sentinelles Network and the network of emergency departments, the 2006–2007 winter outbreak was relatively moderate, with a peak during the first week of January. It affected 1,422,000 people who consulted their general practitioners. In total, 83 clusters of acute gastroenteritis (AGE) occurring between November 15, 2006, and May 1, 2007, were reported to the French Institute for Public Health Surveillance. Noroviruses, particularly the Bristol genotype, were responsible for the majority of the 57 biologically confirmed clusters of cases, with rotaviruses detected in 7 clusters. More than half of the reported clusters (46/83) originated in long-term care facilities for the elderly (EHPA). Discussion-Conclusion. The complementary surveillance systems for GEA in France allow for a good characterization of winter outbreaks in terms of their size and duration, healthcare utilization, and the identification of circulating viruses. The upcoming implementation of a procedure for reporting clusters of GEA cases in long-term care facilities will allow for a more comprehensive and earlier identification of these outbreaks, enhanced investigations, and the rapid implementation of appropriate and effective management measures.
