PARIS, June 16 (Xinhua) -- The COVID-19 strains in France, both those detected during the start of the epidemic and variants found in recent months, have nothing to do with China, local media reported.
Ju referred to the genetic study conducted by scientists from Pasteur Institute, which discovered that the main strain of the coronavirus present in France was linked to a genetic group, or a clade, which had no link with China or Italy.
"Phylogenetic analysis identified several early independent SARS-CoV-2 (the virus that causes COVID-19) introductions without local transmission, highlighting the efficacy of the measures taken to prevent virus spread from symptomatic cases," said the Pasteur Institute.
"In parallel, our genomic data reveals the later predominant circulation of a major clade in many French regions, and implies local circulation of the virus in undocumented infections prior to the wave of COVID-19 cases," it added.
"Pasteur Institute's sequencing results prove that the strains that circulated in France were not the same as the strain in Wuhan, Hubei. Besides, the strains in France were much older," Ju said, quoted by the Paris-based Chinese daily.
The results were confirmed by findings of a French hospital which reviewed the country's first confirmed cases, she added.
In May 2020, doctors at the Albert Schweitzer hospital in Colmar in northeastern France found that the first suspected cases of COVID-19 infection in France could date back to November 2019 after having reviewed 2,456 chest scans performed between Nov. 1, 2019 and April 30, 2020 for all reasons (cardiac, pulmonary, traumatic, and tumor pathologies.)
