COVID-19 - Multicentre Study on Nosocomial Transmission of SARS-CoV-2 Virus: an Ancillary Study (NOSO-COR IMMUNO)
Multicentre Study on Nosocomial Transmission of SARS-CoV-2 Virus: an Ancillary Study
There are still uncertainties about the existence of protective immunity and the duration of protective antibodies in patients infected with SARS-CoV-2. Serological testing is an appropriate tool for epidemiological investigations to assess the persistence of antibodies over time. The nature of the immune response induced by this virus is also poorly understood. This ancillary study aims at assessing the immunological characteristics of patients that participated in the NOSO-COR study at Hospices Civils de Lyon six and twelve months after the initial infectious episode.
Two visits will be scheduled at 6 and 12 months (± 1 month) after the initial SARS-CoV-2 infectious episode, Blood, saliva and nasopharyngeal samples will be collected for seroprevalence and immunological investigation.

OTHER: RT-PCR confirmed COVID-19 patients
RT-PCR confirmed patients included in the NOSO-COR study are invited six and 12 months after the initial infection to provide blood (41.5mL in total), salivary and nasopharyngeal samples and to complete a questionnaire.
Each visit is expected to take about one hour.
