Brief Summary

Chilblains (inflammatory lesion of the feet or hands) have been reported with an unusual frequency during the confinement period, most commonly in children, teenagers and young adults. The aim of the ECCES study is to find out whether these manifestations of chilblains can be linked to the SARS-CoV-2 coronavirus. For this, an epidemiologic study will compare two types of family (or more precisely people who were confined together in March-April-May):

  • "case family" in which at least one of the members had chilblains
  • "comparator family" in which none of the members had chilblains Environment (home lockdown) of the two types of family will be analyzed. Each member of the "family" will be suggested doing a serological test.
