China‘s Ministry of Agriculture and Rural Affairs said on Saturday that the so-called “G4” strain of swine flu virus is not new and does not infect or sicken humans and animals easily, rebuffing a study published earlier this week.
That study, by a team of Chinese scientists and published by the U.S. journal Proceedings of the National Academy of Sciences (PNAS), warned that a new swine flu virus, named G4, has become more infectious to humans and could become a potential “pandemic virus.”
However, China’s agriculture ministry said in a statement that the study has been interpreted by the media “in an exaggerated and nonfactual way.”
An analysis by the ministry concluded that sampling of the published study is too small to be representative, while the article lacks adequate evidence to show the G4 virus has become the dominant strain among pigs.
The ministry said it drew its conclusions after holding a seminar on the G4 virus’s impact on the hog industry and public health. Participants included Chinese veterinarians and anti-virus experts, as well as the leading authors of the PNAS study.
