Severe Acute Respiratory Syndrome-Coronavirus-2 and Loss of Autonomy in the Elderly

In most diseases, older people have less typical symptomatology than that described for younger people. The investigators therefore hypothesize that within the framework of coronavirus disease 19, the clinical pictures in the elderly will present specificities that will need to be described. Moreover, since infection by the severe acute respiratory syndrome (SARS-CoV-2) virus is new to humans, the investigators do not yet have sufficient information on the fate of the elderly, in terms of loss of autonomy, rehospitalization, institutionalization, mortality, etc. the investigators therefore assume that the clinical pictures in the elderly will present specificities that will need to be described. The investigators hypothesize that an acute infection of this type will have short-, medium-, and long-term repercussions in the elderly.
