CDC Warns The Nations With The Swine Flu Strain In China A ‘Potential Pandemic Concern’


China researchers claim to discover the new swine flu with ‘pandemic potential’. According to the officials, the flu can infect humans and has the possibility to cause a future pandemic. On the study that’s been officially released on Monday, the scientists have cautioned that the virus does not pose an immediate global health threat. The disease has been named G4 Virus, as it is genetically descended from the H1N1 swine flu that caused a serious pandemic in 2009. G4 is now showing “all the essential hallmarks of a candidate pandemic virus,” stated in the study, published in the scientific journal PNAS (Proceedings of the National Academy of Sciences)

Has the G4, or the New Swine Flu Strain Hit America?

U.S. health authorities have also tracked a newly discovered strain of swine flu in China, for which they say has the appearances, and features of viruses with the potential to cause a human pandemic. Fortunately, G4 Virus has not been spotted in the U.S. Researchers have conducted surveillance on pigs in China, which found genotype 4 (G4) Eurasian avian-like H1N1 viruses have been detected for over 4 years, as in 2016, they had reported in PNAS.

The Role Of ‘Reassortment’ Process In Generating The New Virus

The G4 Virus strain has genes from a mix of avian, human, and especially pig viruses and also genes from the 2009 H1N1 flu pandemic virus. An animal can be the host to mix up the genetic material through a process that is known as ‘Reassortment’. Mr. Flor M. Munoz, M.D., M.Sc., FAAP, who is a member of the AAP Committee on Infectious Diseases stated the process of ‘Reassortment’ generates the new virus. The new strain looks as if it’s growing incredibly well in human airway epithelial cells and possesses “all the essential marks of being highly adapted to infect humans, in near or far future”, according to the reports.

The Evidence Found of a Past Infection

To make sure the swine flu could be expected as a pandemic disaster, 338 swine farm workers in China found 10% had slight symptoms of a past infection. There is not any evidence reported of person-to-person transmission, but experts expect the virus may continue to mutate and adapt. The CDC or the Centers for Disease Control and Prevention has named the strain a “potential pandemic concern,” because of its originality. There is not any sort of immunity found in the humans that might work properly against this virus, and it seems too different from seasonal flu vaccine strains for the vaccines to prove to be effective. However, there are no signs that show it could be detected there in pigs, and humans in the U.S.
