Elderly Patients and COVID-19 Infection: a Cohort of Fifty Patients Over Ninety Years of Age

Study Overview
=================
Brief Summary
-----------------
SARS-CoV2 or CoVid19 disease is a newly described pathology linked to a subtype of the coronavirus family identified in China in December 2019. This pathology can present multiple clinical facets, ranging from asymptomatic forms to more commonly critical pulmonary forms called Acute Respiratory Distress Syndrome. The elderly population is more at risk for this infection due to the senescence of the immune system, co-morbidities and poly medications. They also often present a greater state of fragility. This study aims to report the epidemiology of the first 50 patients over 90 years of age hospitalized within the CHU Brugmann hospital.
