Prevalence of COVID-19 in a French Dependent Care Facility for the Elderly and in a French Long-term Care Unit: Observational Study

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the prevalence of COVID-19 among the residents and geriatric inpatients of the care facilities attached to the Centre Hospitalier Sud Essonne (a general hospital located in Ile-de-France, France), and the factors that are likely to influence this prevalence.

Detailed Description
-----------------
Among people exposed to the COVID-19 (SARS-COV-2) pandemic, elderly people are considered as particularly vulnerable, especially those living in nursing homes or hospitalized. Furthermore, facilities / accommodations are registered among the main locations of COVID-19 clusters. These observations have led the French government to establish specific protection measures and survey dependent care facilities for the elderly and long-term care units in the hospital. With these new standards established, a long-term study of all the residents and geriatric inpatients of the care facilities attached to the Centre Hospitalier Sud Essonne (a general hospital located in Ile-de-France, France), can provide additional knowledge on COVID-19.
