Bronchiolitis

This interpretation remains to be confirmed due to the holidays and the end-of-year festivities, which may have influenced these trends.

  • All age groups are affected.

  • A slight decrease in the number of visits to SOS Médecins has been observed.

  • The holidays and the end-of-year festivities may have influenced these trends.
