Week 07-2022:

• SOS-Médecins: 378 consultations for influenza-like illness recorded, representing 4.5% of total activity (compared to 5.2% in week 06). However, due to a data transmission issue, data has been incomplete since February 16, 2022; this indicator should therefore be interpreted with caution.

More than 75% of visits involved children under 15 years of age (81% in week 06) and, more specifically, children under 5 years of age (51% compared to 56% in week 06).
