About twenty cases of the English variant of the Sars-Cov-2 coronavirus have been detected in France. How is it monitored nationally? Explanations.
Appeared in mid-December in the United Kingdom, the “English variant” of the Sars-Cov-2 coronavirus is now present in France: as of January 7, 2021, 19 cases had been identified in France. More contagious than “version 1” of the coronavirus, this English variant (called VOC 202012/01 by doctors) would not cause more severe symptoms.
Asked by our colleagues from France Info, Pr. Jean-François Delfraissy, President of the Scientific Council, said “very concerned“by this mutation of the Sars-Cov-2 virus:”the question is not to block it, but to slow it down (…) We’re in a kind of speed race between (…) the ineluctable appearance of this English variant which can lead us to (…) several tens of thousands of people affected (…) and the ability to immunize the most vulnerable people. We are in this race for the next three months.“
How to track this English variant to better slow it down?
Faced with the progression of this worrying mutation, a national investigation concerning all positive screening tests for Covid-19 carried out this Thursday January 7 and this Friday January 8, 2021 has been launched. The goal ? “It is to have a photograph, to measure the percentage of variant among all the positive cases“explained epidemiologist Arnaud Fontanet to our colleagues from Sunday newspaper. The results of this work are expected this week.
This major investigation takes place in two stages. First, it involves identifying the “dubious” screening tests using a specific PCR test: produced by Thermo Fisher, this test is able to differentiate between the Sars-Cov-2 coronavirus and its “clone” British. Deuzio, the “dubious” tests are subject to genetic sequencing to confirm the presence of VOC 202012/01, the famous “English variant”.
Sequencing, this painstaking work of determining whether a sample is infected by the Sars-Cov-2 coronavirus or by its British “clone”, is carried out in about twenty centers in France: the National Reference Center for Lyon respiratory infections can currently analyze 200 per week. In total, this analytical work takes between 3 and 5 days.
At present, 1.36% of the samples analyzed are considered suspect. If this may not seem like much, Laurent Kbaier, medical biologist and spokesperson for Biogroup, affirms that it is important to react without delay: “Denmark worried at 0.2%. A month later, they were at 2%, it’s exponential“.
