• Regionally, flu activity continues to rise, both in emergency departments and at the SOS Médecins association in Meurthe-et-Moselle. It is comparable to what was observed two years ago, during the 2012-2013 winter season. Nationally, the epidemic continues, with no observed increase in the proportion of hospitalizations due to the flu.

These influenza viruses are known to cause complications in at-risk individuals (see the InVS-National weekly influenza bulletin).
