Key Findings

• In Lorraine, the number of allergy cases diagnosed by emergency services remains within the usual fluctuations observed during this period, compared to data from 2014 and 2015, and accounts for just under 1% of these services’ activity. In Meurthe-et-Moselle, allergy diagnoses account for approximately 2.5% of SOS Médecin’s activity, with 19 and 18 allergy cases diagnosed in weeks 16 and 17, respectively.

• After a peak observed in week 16 (89 cases), the weekly number of asthma diagnoses in emergency departments dropped to 61 cases in week 17. These variations remain within the usual fluctuations observed during this time of year.

• According to the National Aerobiological Surveillance Network (RNSA), the allergy risk is high to moderate depending on the department in Lorraine: high in the departments of Meuse, Meurthe-et-Moselle, and Moselle, and moderate in the Vosges.

• An increase in gastroenteritis diagnoses was observed from week 11 (250 cases) to week 16 (220 cases), with a peak in weeks 12 and 13 (approximately 280 cases).In-depth analyses have shown that the Moselle department is the most affected and that the under-5 age group is the most impacted. In week 17, with 200 diagnosed cases, this condition accounts for nearly 2% of the region’s emergency department activity (see page 5). This increase observed during this period in 2015 was not seen in 2014 or 2013. An investigation is underway to determine the cause of this increase.

• The number of gastroenteritis cases diagnosed by the SOS Médecins 54 association remains within the usual fluctuations for this time of year, even though these diagnoses account for a significant portion of their caseload (approximately 7% of their total caseload).

• Data from the virology laboratory at Nancy University Hospital appear to indicate a resurgence in the circulation of rotaviruses since week 11, with an increase in the number of positive samples and a predominance of this virus compared to other enteric viruses.

• Respiratory viruses other than influenza (A or B) are circulating at levels typically observed, according to data from the virology laboratory at the Nancy University Hospital.
