Over the past week in the region:

• The start of the flu season has been confirmed in the region. The increase mainly affects children aged 2 to 15, with a more pronounced rise in visits to SOS Médecins clinics than in emergency room visits. No significant impact has been observed among the elderly, whether in nursing homes or in emergency rooms. Two cases of severe type A influenza in adults have been hospitalized in intensive care in the region. The number of influenza virus isolates by the virology laboratories of the region’s two university hospitals is also on the rise. Nationally, type B viruses are predominant in private practice consultations.

• An increase in cases of gastroenteritis seen by SOS Médecins, reaching epidemic threshold levels. The number of clusters of gastroenteritis cases in nursing homes has continued to rise since early January. Nationally, the new norovirus genotype (GII.17) is becoming dominant over the older GII.4 virus.

• Moderate persistence of bronchiolitis cases in the pediatric emergency department at Nantes University Hospital.
