Key Points

COVID-19

• Testing and incidence rates decreased in S51. The positivity rate is also decreasing (24.1% vs. 28.5% in S-1). This trend is consistent with the overall trend observed in France.

• The Omicron variant is circulating almost exclusively in the region, with the BA.5 sublineage predominating, accounting for 96% of interpretable sequences from the Flash S49 survey (based on 89 interpretable sequences as of December 5). Among its sublineages, BQ.1.1 (including its sublineages) is the most frequently detected.

• The share of COVID-19 cases in the total caseload of SOS Médecins associations is decreasing (2.1% vs. 4.3% in Week 1), and the share of suspected COVID-19 cases in emergency departments remains stable compared to last week (1.7% vs. 1.8% in Week 1).

• The weekly number of new hospitalizations is decreasing for the second consecutive week (386 vs. 499 in W-1 and 550 in W-2). The number of new admissions to intensive care is stable (31 vs. 34 in W-1), as is the number of in-hospital deaths (36 vs. 33 in W-1).

Bronchiolitis

• Epidemic phase

• The region has been in the epidemic phase for 11 weeks

• Bronchiolitis activity among children under 2 years of age has been decreasing in emergency departments for the past two weeks (Figure 4) and has risen slightly for calls to SOS Médecins.

Influenza

• Epidemic phase

• The region has been in the influenza epidemic phase for the fourth consecutive week: activity continues to increase exponentially in emergency departments and among SOS Médecins cases.

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

• 4 severe cases of influenza admitted to intensive care reported by the intensive care sentinel network

Acute gastroenteritis

• Activity rates at SOS Médecins clinics are stable, close to the levels observed during the 2020-21 season.

• Activity rates in emergency departments are high but remain below last season’s levels.
