Key Points

COVID-19

• The Omicron variant is circulating almost exclusively in the region, with the BA.5 sublineage predominating, accounting for 93.5% of interpretable sequences from the Flash S50 survey (based on 62 interpretable sequences as of December 12). Among these sublineages, BQ.1.1 is the most frequently detected.

• The share of COVID-19 cases in the total caseload of SOS Médecins associations is decreasing (1.3% vs. 2.1% in Week 1), as is the share of suspected COVID-19 cases in emergency departments (1.3% vs. 1.7% in Week 1).

• Epidemic phase.

• The region has been in the flu epidemic phase for the fifth consecutive week: activity is beginning to decline across all age groups in emergency departments and at SOS Médecins. However, the number of hospitalizations is still on the rise.

• 21 reports of clusters of acute respiratory infections in long-term care facilities.

• 11 severe cases of influenza admitted to intensive care reported by the intensive care sentinel network, including 3 in pediatric intensive care.
