Retrospective Study of Pediatric Patients With Covid-19 in Alsace in 2020-2021

Study Overview
=================
Brief Summary
-----------------
Covid-19 is an illness that appeared in China between the end of December 2019 and the beginning of 2020 after several cases of pneumonia of undetermined etiology were reported in the Hubei province in central China. These are caused by a previously unknown coronavirus, initially named 2019-nCoV then SARS-CoV-2, which was identified on January 7, 2020 in the Bronchoalveolar Lavage (BAL) of patients hospitalized in China. As for the first European cases, they were diagnosed in France on January 24, 2020. A Chinese study published in April 2020 (4) concerning adult patients showed that 14% of these cases could be defined as severe and that 5% of cases could be defined as critical. Another Chinese study showed that all children, regardless of age, could be infected and that asymptomatic, mild and moderate cases accounted for more than 90% of cases. In France, the Covid-19 epidemic hit Alsace hard from March 2020, mainly due to the cluster formed by the evangelical assembly of the Christian Open Door Church taking place from February 17 to 21 in Mulhouse in the Haut-Rhin. Thus, it is interesting to study pediatric patients hospitalized for Covid-19 in Alsace during 2020 in order to discover the clinical characteristics of these patients.
