SOS Médecins' activity has increased slightly nationwide and in most regions over the past week; however, overall activity remains below the levels observed in 2011 for the same period. This increase is primarily among children under 15 years of age (+18%). The flu indicator is on the rise nationwide (+27%), across all age groups and particularly among those under 15 (+60%). This indicator accounts for 2.5% of the associations’ total activity and remains, nonetheless, well below the figures observed last year for the same period. The bronchiolitis indicator has increased over the past week (+17%); for this condition, diagnoses account for 5% of SOS Médecins’ activity for children under 2 years of age nationwide. This trend is comparable to that observed in 2011 for the same period. The gastroenteritis indicator is stable across the associations (10% of total association activity); however, a slight increase is observed among those under 15 years of age (+17%). The trends observed for the influenza, bronchiolitis, and gastroenteritis indicators are comparable to those observed in the emergency departments of the OSCOUR® network for the past week. The measles indicator is stable over the observed period. The death indicator is slightly higher, comparable to the trends observed in 2011 and 2010 for the same period. The most frequently observed condition nationwide is gastroenteritis. Over the past week, ENT and respiratory conditions (tonsillitis, nasopharyngitis, tracheitis, flu-like syndrome, and bronchitis) have increased across all age groups, particularly among children under 15.
