Key Points

Acute Gastroenteritis

• High activity in emergency departments

• Gastroenteritis-related activity in Week 17 has decreased in emergency departments, though it remains higher than during the same period in the two previous seasons over the past four weeks (1.9% vs. 2.2% in Week 1).

• The under-15 age group accounts for the majority of activity in emergency departments.

• Activity at SOS Médecins clinics has decreased: 5.7% (vs. 8.7% in Week 1), returning to the activity rates observed in previous years.

Notifiable Diseases (ND)

• The Regional Unit has real-time data on five notifiable infectious diseases reported in Bourgogne-Franche-Comté: invasive meningococcal disease (IMD), hepatitis A, Legionnaires’ disease, measles, and foodborne illness outbreaks (FBO).

• Results are presented based on the date of rash onset for measles (if missing, it is replaced by the date of specimen collection or hospitalization and, as a last resort, by the date of notification), the date of hospitalization for IIM, the date of symptom onset for hepatitis A and Legionnaires’ disease, and the date of the first case for foodborne outbreaks (if missing, it is replaced by the date of the meal or the last case, or, as a last resort, by the date of the outbreak report).
