The Covid-19 virus which has been ravaging France may not have originated in China, according to a study published by virologists at the Pasteur Institute in Paris. The French strain may have been circulating locally and unrecognised before the global outbreak accelerated.
Tests on samples from 97 French and three Algerians infected with Sars-CoV-2 suggest that the virus may have been around in France before the pandemic started.
Van der Werf, Simon-Loriere e.a: "Introductions and early spread of SARS-CoV-2 in France"
The sixteen-page study, by researchers affiliated with the prestigious Pasteur Institute in Paris, was first reported by Hong Kong’s South China Morning Post, and says that already on 10 January, France implemented “strengthened surveillance of Covid-19 cases,” five days after the World Health Organisation issued the first “Disease Outbreak News” on a “pneumonia of unknown cause” which was first reported by China on 31 December 2019.
Genetic analysis of the samples revealed that the dominant types of viral strains in France belonged to a “clade” or group with a common ancestor that did not come from either China or Italy.
“The French outbreak has been mainly seeded by one or several variants of this clade … we can infer that the virus was silently circulating in France in February,” write the researchers.
