Epidemics have always affected the most disadvantaged social categories more intensely. This social inequality is expressed in the use of care and emergencies: greater frequency but also greater seriousness. Our hypothesis is that, during a period of confinement, the most disadvantaged populations are more affected by the COVID-19 infection than the rest of the population. The number of remedies is greater, as is the severity of the forms of infection.
