Building a collection of human biological samples in France (CORSER project - A seroepidemiological study of the SARS-CoV-2 virus)

Aim: to detect the presence of specific SARS-CoV-2 antibodies in different populations, either those who traveled to China in the weeks preceding the start of the outbreak, or those with suspected infection with SARS-CoV-2. The aim is to understand: When and how the virus was transmitted from animals to humansWhen the virus began circulating in humans in FranceHow long the infectious period lastsWhat percentage of patients experience few or no symptomsTo answer these questions, the scientists will carry out the first seroepidemiological studies (detecting coronavirus antibodies in patients) of SARS-CoV-2 infection, while also developing a serological test. Samples will be taken:- from subjects who traveled to China during the period from August 1, 2019 to January 31, 2020 and who were not diagnosed as infected with SARS-CoV-2 (CORSER-1);- from suspected cases of SARS-CoV-2 infection that tested negative for the virus with the RT-PCR assay on a respiratory sample; contacts or individuals exposed to confirmed cases of SARS-CoV-2 infection; or individuals who worked or stayed in a hospital where confirmed cases of SARS-CoV-2 infection were treated (CORSER-2).
