- 1,440 cases of Omicron variant infection confirmed by sequencing in France as of 23 December
Mental Health
High-level stability of mental health indicators (states of depression and anxiety, sleep problems and suicidal thoughts) in the CoviPrev survey (wave 30, 30 November-07 December 2021)
Prevention
- Vaccination on 22 December 2021 (Vaccin Covid data):
- 76.8% of the French population had received a complete primary vaccination series
- 39.0% of the 18+ age group (79.4% of eligible people) and 68.1% of the 65+ age group (86.9% of eligible people) had received a booster shot
- Importance of combining different measures: complete vaccination series (including complete primary series and booster), adherence to contact tracing and preventive measures. Compliance with prevention measures, including reducing contacts and frequently ventilating enclosed spaces, is essential during the end-of-year festive period in the context of the circulation of the Omicron variant
