  1. Bold is used to underline % and OR
  2. 1Home sampling for finger prick/Euroimmun ELISA-S test
  3. 2People aged 15 or over, living in mainland France, but not in residential care homes for the elderly or prisons
  4. 3The sampling design is taken into account for the estimation of prevalence, crude and adjusted odds ratios, confidence intervals and tests, with the SAS procsurvey procedure. The percentages are weighted by sampling weight (the inverse of e inclusion probability), corrected for non-response probability and calibrated on the margin of the census. The prevalences are not equal to n/N
  5. 4First-generation immigrants: born non-French outside France and living permanently in France (including those who subsequently acquired French nationality)
  6. 5Second-generation immigrants: born and living in France, with at least one parent a first-generation immigrant
  7. 6Including medical and paramedical professionals, Firefighters, Pharmacists and ambulance drivers (but not including hospital cleaners, for example)
  8. 7Home helps or housekeepers, food shop workers, delivery drivers, public transportation drivers, cab drivers, bank customer service or reception staff, petrol station employees, police officers, postal workers, cleaning staff, security guards, construction workers, truck drivers, farmers and social workers
