Key Points

• In week 45 (November 4–10, 2024), emergency department visits increased compared to the previous week among children under 15 years of age (+9%, or +7,230 visits), and remained stable among adults. Hospitalizations following emergency department visits followed the same trend.

• The increase in visits among children is mainly driven by respiratory conditions: ENT infections (+28%, or +2,331 visits), asthma attacks (+60%, or +1,439 visits), pneumonia (+46%, or 275 visits), acute bronchitis (+46%, or +142 visits), cough (+39%, or +384 visits), bronchiolitis in children under 2 years of age (+44%, or +733 visits), and influenza/influenza-like illness (+61%, or +141 visits). The share of activity for these various indicators remains at levels comparable to (or even lower than, for ENT infections, bronchitis, and bronchiolitis) those observed in previous years.

• Among adults, respiratory indicators remain stable, except for visits for asthma attacks (+9%, or +119 visits) and influenza/flu-like illness (+25%, or +130 visits).

• Furthermore, among children, there was an increase in visits for isolated fever (+15%, or +452 visits), gastroenteritis (+9%, or +167 visits), and vomiting among 2- to 14-year-olds (10%, or +62 visits).
