Trends in Seasonal IndicatorsWith 2,878 visits over the past week, emergency room visits for influenza/flu-like illness are up 64% among children under 15 (i.e., +621 visits) and 46% among adults (+404 visits). The numbers follow the trend of the 2012–2013 epidemic, with figures very close to those of 2013 and significantly higher than those of 2014. At the regional level, visits for influenza/influenza-like illness are beginning to rise in the northern and eastern regions and are showing a marked increase in the other regions.Emergency department visits for gastroenteritis are stable across all age groups, with numbers comparable to those of 2014 and lower than those of 2013. At the regional level, the number of visits remains stable in all regions except for the Île-de-France region, where the number of visits is rising slightly. The temporal trend compared to the two previous seasons indicates that the epidemic peak has likely passed in all regions. Indicators for pneumonia and ENT infections are rising among children under 15, by +18% (+104 visits) and +21% (+258 visits), respectively. Visits for asthma and acute bronchitis are also slightly up for this age group (+9% and +7%, respectively).

Across all age groups, the numbers for these four indicators remain higher than those of the previous two years. Among children under 2 years of age, emergency room visits for bronchiolitis are up 12%. The trend and numbers are consistent with those of the previous year.
