While hospitalizations are currently decreasing, the unusual timing and pattern of these cases warrant attention. This article provides an update on the current situation,focusing on trends observed in France and offering context on influenza and related respiratory infections.
Recent trends in France
Data reveals a notable increase in emergency department visits related to flu-like syndromes. Visits rose from 56 in week 01 to 76 in week 02. A meaningful proportion of these cases involve young children and older adults. Specifically, individuals under five years of age account for approximately one-third of cases, while those over 65 represent 32% in week 01 and 16% in week 02. The rate of emergency room visits has also increased, from 1.4% in week 01 to 1.8% in week 02.
Conversely, hospitalizations for flu-like illnesses have shown a decline, decreasing from 16 in week 52 of 2025 to 13 and 10 in weeks 01 and 02 of 2026, respectively. The majority of hospitalizations are among individuals aged 65 and older.
General practitioner data suggests a decrease in consultations for acute respiratory infections (ARIs). The proportion of activity related to ARIs was 6.2% in week 01, decreasing to 4.6% in week 02. Though, it’s significant to note that this data might potentially be influenced by recent physician strikes and school holidays, possibly affecting data collection accuracy.
