Trends in Overall Activity: The number of visits and hospitalizations remains stable across all age groups, except for children aged 2–14, where a slight increase in visits has been observed. The total number of cases across all age groups is higher than that observed during the same period in 2014.

Trends in the Most Common ConditionsAmong children under 2 years of age, visits for influenza/flu-like illness are rising sharply (+84%), though the total number remains low (254 visits). Visits for other major conditions are stable or declining, particularly for bronchiolitis (-22%). Among children aged 2 to 14, the increase in visits for trauma (+15%, or +2,225 visits) continues this week, and other indicators such as ENT infections, abdominal pain, isolated fever, asthma, and influenza/flu-like illness are on the rise. The main conditions are stable or declining among adults.

Trends in Seasonal Indicators: Emergency room visits for influenza/influenza-like illness are on the rise (doubling in number) among children under 15 years of age (i.e., +518 visits) but are stable in other age groups. With 1,919 weekly visits, the numbers are very close to those of 2013 and significantly higher than those of 2014. At the regional level, visits for influenza/flu-like illness are increasing in all regions except the North.Emergency department visits for gastroenteritis are decreasing among adults (-16%) but increasing among children under 2 years of age (+18%). At the regional level, there is a decrease or stability in the number of visits in all regions except for the Southeast and the Île-de-France, where the number of visits is slightly increasing. The temporal trend compared to the two previous seasons indicates that the epidemic peak has likely passed in all regions. For other indicators such as acute bronchitis, pneumonia, asthma, and ENT infections, the number of visits continues to decline this week among adults over 15 years of age. In contrast, among children aged 2 to 14, an uptick in visits is observed, with modest increases for acute bronchitis (+35%, or +85 visits) and pneumonia (+10%, or +35 visits), but a more significant rise for asthma (+52%, or +349 visits) and ENT infections (+32%, or +1,041 visits). These indicators remain stable among children under 2 years of age. Among children under 2 years of age, emergency department visits for bronchiolitis have decreased by 22%, with a peak in visits across all regions and numbers very close to those of previous years.
