At the Métropole Savoie hospital, to deal with the daily influx of severe patients during the second wave of COVID-19, 23 patients had to be transferred away from their home city and far from their families as part of a medical evacuation (EVASAN).~The purpose of the study is to investigate whether there is an association between medical evacuations and the occurrence of psychological disorders such as post-traumatic stress, anxiety or depression occurring within 6 to 10 months in families of evacuated patients.~The investigators want to compare the prevalence of psychological disorders in the families of patients evacuated for a serious form of COVID-19 (cases) compared to that of families of patients not evacuated (controls) hospitalized for a serious form of COVID-19.
