Key Points

• SOS-Médecins: 2,188 consultations for flu-like illness recorded, representing 19.5% of total activity (compared to 16.3% in week 11). However, due to a data transmission issue, data has been incomplete since February 16, 2022; this indicator should therefore be interpreted with caution.

• Oscour®: 627 emergency department visits for influenza or influenza-like illness, representing 2.0% of total activity (1.4% in week 11), of which 12.8% resulted in hospitalization. The majority of these visits involved children under 15 years of age.
