It is one of the first departments in France to have been affected by Covid-19 with an epidemic outbreak that developed in early March in the municipalities of Crac'h, Auray and Carnac. Three months later, we know more about the spread of the virus in Morbihan with the publication of the results of a retrospective serological survey conducted in early May with a sample of 1,252 people.
According to this study, managed by the company Open Health, 9.7% of the population of the department would have been in contact with the coronavirus, that is to say a little more than 70,000 inhabitants. The results were transmitted to the Scientific Council which recommended additional analyzes "which will be carried out soon", indicates the departmental council of Morbihan in a press release.
The virus has circulated more but less killed than at the national level
In the meantime, the community is already drawing some conclusions on the circulation of the epidemic on its territory. "The observation is made of a significantly higher prevalence of the disease than indicated by the models disseminated by the Ministry of Health and therefore of lower lethality," said the departmental council.
“This also demonstrates a significant past circulation of the virus within the Morbihan population, all areas combined, far beyond severe hospitalized cases, or positive cases tested reported by the ARS, and suggests a significant rate of asymptomatic or pauci-symptomatic ”, continues the press release.
François Goulard, Chairman of the Morbihan Departmental Council, now wishes this study to be carried out on a national scale "in order to monitor, in real time as well as retrospectively, the spread of the epidemic and to better base prophylaxis measures".
