Key points

In week 45, the incidence rate based on antigen tests was on a stabilising trend. New hospital admissions and number of deaths continued to decline.

  • Metropolitan France:
    • A slowdown in the drop in incidence rate from antigen tests corrected for the public holiday (11/11)
    • Increase in the incidence and positivity rates based on antigen tests in the under-20 age group
    • Less significant decrease in new hospital admissions
  • Overseas France:
    • Corrected incidence rates based on antigen tests at low levels but rising in Martinique, French Guyana and Mayotte.


  • Omicron sub-lineages: Mostly BA.5 with 93% of sequences in the week 43 Flash Survey (24/10)*
  • Among the BA.5 sub-lineages, BQ.1.1 continues to rise (32% vs 25% in the week 42 Flash survey)


  • Vaccination on 14 November 2022 (Vaccin Covid data):
    • 82.7% of the population aged 65+ had received at least one booster dose.
    • 34.6% of 60-79 year-olds (representing 41.0% of those who are eligible given the date of their last injection) and 41.1% of those aged 80 and over (53.5% of those eligible) had received their second booster dose.
  • Given the ongoing active circulation of SARS-CoV-2 and the approach of the winter season, compliance with the  combined measures remains essential:
    • up-to-date COVID-19 vaccination, through a booster dose with a bivalent vaccine (against the initial strain and the Omicron variant of SARS-CoV-2) for eligible individuals already vaccinated with a primary course;
    • isolation in the event of a positive COVID-19 test and/or symptoms;
    • continued application of preventive measures, including wearing a face mask – particularly around people at risk of developing complications, as well as in enclosed spaces favourable to transmission (e.g. public transport) or during large gatherings – hand washing and ventilation of enclosed spaces.
