Overseas Network, March 17On the night of the 15th local time, the French General Health Administration announced that a new variant of the new coronavirus had been found in the Lannion hospital, Côtes-d’Armor, Brittany.

According to French TV 3, this new mutant coronavirus was discovered in a cluster of infections that broke out at La Nyon Hospital in late February. As of March 13, 79 patients had been diagnosed with this cluster infection. After genetic sequencing, 8 of them belonged to a new, previously undiscovered mutated coronavirus infection.

According to the British Health Agency, this new variant of the new coronavirus will not be more contagious than the original strain, nor will it cause more serious forms of infection. However, the French health department remains on the lookout for this new strain and is currently conducting in-depth research to better understand this mutant virus and its effects.

In addition, this new variant of the new coronavirus has a special problem, that is, it is difficult to confirm whether it is infected by nucleic acid tests by RT-PCR. That is, the infected person will have symptoms, but the result of the nasopharyngeal sampling RT-PCR test is still negative, and the diagnosis must be confirmed by taking samples from the deeper airways or serum test.

The new strain discovered in Britain has been included in the list of new mutant coronaviruses controlled by the World Health Organization. Unlike the newer strains found in the UK, Brazil or South Africa, this new strain is not considered very concerning at this stage. However, Philip Froger, an expert at the Lille Medical Center, France, called for caution against the new mutant coronavirus discovered in Brittany. He explained: “It took us 6 months to really determine that the new mutant coronavirus discovered in the UK is more contagious and deadly. This means that we cannot make a light claim today about the mutant virus discovered in Britain. There is still a lot of scientific work before. to judge whether it is riskier. “

Brittany is a region less affected by the new corona epidemic in France. The current incidence (the number of confirmed cases per 100,000 inhabitants per week) is 132.9, well below the national average of more than 240 cases. However, following the discovery of new strains, as preventive measures, local governments and health institutions are strengthening measures to contain the spread of the virus, such as speeding up vaccination and reminding people to pay attention to protection. Côte d’Amour requires that people over the age of 11 wear masks when going out and drinking alcohol on public roads is prohibited. The decree is valid until April 7. The towns of Lannion, Guingamp, Saint-Brieuc and Morlaix in Brittany have established detection systems for this new strain. (Overseas Network-Paris-Lu Jia)Return to Sohu to see more
