Key Points

In week 47, an acceleration in SARS-CoV-2 transmission was observed based on virological indicators (calculated using antigen tests alone and all tests combined), as well as on indicators of healthcare utilization. Hospital indicators (unconsolidated) remained stable at the national level.

• Mainland France:

  • Incidence rates continue to rise

  • Positivity rates continue to rise

• Overseas territories:

  • Increase in incidence rates in nearly all regions

Variants

• Omicron sublineages: BA.5 ubiquitous, accounting for 93% of sequences in the Flash S45 survey (11/07)*

• Among BA.5 sublineages, BQ.1.1 continues to rise (49% in Flash S45 vs. 34% in Flash S43)

Prevention

• Vaccination as of November 28, 2022 (Covid Vaccine data):

  • 7.2% of those aged 60–79 had received a booster tailored to the Omicron variant (10.0% of those eligible). Additionally, 31.6% of them are considered protected by vaccination;

  • 9.4% of those aged 80 and older had received a booster tailored to the Omicron variant (11.3% of those eligible) and 13.0% are considered protected by vaccination.

• Given the active circulation of SARS-CoV-2, as well as several winter viruses, it is necessary to strengthen adherence to the various combined measures:

  • up-to-date COVID-19 vaccination, particularly through a booster dose with a bivalent vaccine (against the original strain and the Omicron variant of SARS-CoV-2) for those eligible who have received their primary series; isolation in the event of a positive COVID-19 test and/or symptoms;

  • continued adherence to preventive measures: wearing a mask (in the presence of vulnerable individuals, in crowded indoor spaces such as public transportation), handwashing, and ventilation of enclosed spaces.
