Prevention

  • Vaccination on 19 September 2022 (Vaccin Covid data):
    • 74.3% of the population aged 18+ and 82.4% of people aged 65+ had received a booster dose
    • 28.7% of 60-79 year-olds (representing 34.2% of those eligible given the date of their last injection) and 36.4% of people aged 80+ (47.8% of those eligible) had received a second booster dose
  • Given the acceleration in circulation of SARS-CoV-2, compliance with the combined measures remains necessary:
    • staying up-to-date with COVID-19 vaccinations, including the second booster dose for vulnerable people;
    • self-isolation in case of a positive test for COVID-19 and/or symptoms;
    • continued application of precautionary measures, including wearing a mask, particularly around people atrisk and in enclosed areas favourable to transmission (especially public transport and large gatherings), as well as frequent hand washing and ventilation of enclosed spaces.
