Nationally, the weekly number of cases has been below the epidemic threshold since week 13 (March 23–29).

• In week 14, the majority of circulating respiratory viruses were enteroviruses or rhinoviruses.

• The weekly number of diagnoses of acute gastroenteritis and diarrhea is stable and accounts for 10 to 12% of the total number of diagnoses made by each of the associations in week 15.

• Asthma-related activity is on the rise: 16 weekly diagnoses made by each of the associations in week 15. This activity accounts for a maximum of 2% of the total number of diagnoses made.

• According to the National Aerobiological Surveillance Network (RNSA), the allergy risk is moderate in both Alsatian departments.
