Covid19 Clinical Trial
Official title:
Biological Collection for the Study of the Relationship Between the Biological Profiles Observed and the Clinical Evolutions Within the Same Cluster of Transmission of the Coronavirus SARS-CoV-2
The hypothesis is that from a cluster defined by a confirmed positive case of COVID-19 and its contact cases, it is possible to study the different expressions and clinical evolutions of COVID-19 infection and to explore the biological profiles related to the observed clinical history. Certain biological determinants (virological, immunological, microbological or gentic) could indeed be correlated with the clinical presentation and/or be useful for personalized care. The main objective is to study the relationship between the biological profiles observed and the clinical evolutions within the same cluster of transmission of the coronavirus SARS-CoV-2 (positive COVID-19 cases and contact subjects).
Subjects with a COVID-19 infection and thei contact cases (identification according to health insurance criteria, see "Améli.fr") will be offered a clinical evaluation and the takin of biological samples, whether they are hospitalized or via the outpatient screening channel. For the main objective: during the D0 visit, the subjects who agreed to participate in the study will have a clinical evaluation according to a standardized questionnaire and a nasopharyngeal swab, saliva, blood, stool and urine. For secondary objectives : longitudinal follow-up will be carried out for 21 days, for index cases and contact cases, whether they have a positive or negative RT-PCR test on D0. A final consultation will be carried out at M3. Nasopharyngeal samples, saliva, blood, stool and urine will be taken on D10 and D21. A blood test will be taken at M3 to carry out a COVID-19 serology. ;
