Should we be worried about the new swine flu discovered in China?

In China, researchers have discovered a new family of swine flu virus that has all the characteristics that could cause a future pandemic. Should we be worried? Response with a specialist.

American scientific journal PNAS, Chinese researchers have discovered a strain of swine flu virus in China with all the characteristics capable of causing a future pandemic. These viruses, which are called G4, are genetically descended from the H1N1 strain, causing a pandemic from 2009 to 2010. “data-reactid =” 24 “> This is a discovery that we would have done well. study published in the American scientific journal PNAS, Chinese researchers have discovered a strain of swine flu virus in China with all the characteristics capable of causing a future pandemic. These viruses, which are called G4, are genetically descended from the H1N1 strain, which caused a pandemic from 2009 to 2010.

Scientists from Chinese universities and the China Center for Disease Prevention and Control said the viruses “have all the essential traits that show high adaptability to infect humans.” The G4 has been found in more than 10% of workers and people working with pigs, a considerable figure. The virus has therefore already spread to humans, but there is as yet no evidence that it can be transmitted from human to human.

“Nothing special”

If the statements of these scientists can be scary, Professor Bruno Lina, virologist at the University Hospital of Lyon, is reassuring concerning this strain of virus which is “nothing extraordinary”. “These are viruses that are used to circulating. There are currently, as well in Europe as in Asia or in the United States, a certain number of other lineages of virus which present approximately similar characteristics, which thus comprise genes which come from human H1N1 viruses , but potentially other viruses as well. ”

No reason to panic, according to the professor of virology at the University of Lyon 1, who claims that this virus cannot cause a pandemic similar to the one we are currently experiencing with Covid-19: “This announcement is not everything synonymous with a short-term health emergency. We are in great normality. There are many other H1N1’s, it’s a non-phenomenon. The veterinarians responsible for monitoring swine flu will confirm this. ”
