Brief summary

The COVIDOR epidemiological study. Our study would be the first at the community level in Orleans Métropole, aiming to determine the link between a positive IgM level on the serological test and a healthy carrier of covid-19 in agents in contact with the public. It would provide epidemiological surveillance of anti-covid-19 immunity in the community

Detailed description

The metropolitan area of Orléans Métropole has 6,700 agents divided into 250 different trades and consequently multiple exposures and risks. The global covid-19 pandemic has affected France and the Loiret, the sarscov-2 coronavirus, has infected several thousand people. On May 7, 2020, there were 75 deaths at the CHRO hospital in Orleans, excluding EHPAD. The contamination rate of the population of the Loiret department has been estimated at 5.6% of the population by Public Health France. This rate is very low and does not allow the use of serological screening tests because of too many false positives or false negatives, there should be a prevalence of the disease greater than 60%. The French health authorities do not recommend the use of a screening test at the present time in view of the uncertainties of the results of this test. The Loiret Management Center, the Department and Orléans Métropole have decided to offer a covid-19 serological screening test, the covid-19 presto test, to voluntary territorial agents regardless of their return to work following the national deconfinement on May 11, 2020 This can only be done through an epidemiological surveillance study validated as part of a research protocol.

Design outcomes

Primary

Measure	Time frame	Description
Study the prevalence of Covid-19 infection, coronavirus (SARS coronavirus-2) in territorial agents in the 3 structures : CCTVL, Loire Valley Region Centre, Orleans Metropolitan city	15 minutes	Covid-19 attack rate by measuring the frequency of anti-covid-19 IgM in each of the territorial structures
