my country finds that the new type of recombinant pig influenza virus may have a common disease of human and animals.

According to the China Centers for Disease Prevention and Control, a study published by the School of Public Health of the University of Hong Kong recently pointed out that in China, H9N2 bird flu virus is infected with pigs and reorganized with pig flu viruses. Based on the existing research, the virus strain has the possibility of spreading human and animal diseases.

Pig influenza virus is an important pathogen of human beast. Previous studies have found that poultry and human A type A influenza virus can be infected with pigs at the same time, and new people and animals are common, which has the possibility of potential popularity.

In new studies, the researchers collected samples of pig nose swabs at different time periods to compare the separated type A influenza virus.

From April 2021 to February 2022, a total of 829 pig nose swabs were collected, and 8 A type of influenza virus was separated: 7 from August 2021 and one from September 2021.

Researchers have found that the type A influenza virus detected in August 2021 is H3N2 virus, and its internal gene fragments come from the H1N1 type A virus spectrum.

The type A influenza virus separated in September 2021 is a re -assignment between multiple pig flu. Part of the gene fragment of the virus belongs to the poultry H9N2 virus subtype, which includes gene fragments derived from the PH1N1 spectrum and Eurasian poultry H1N1 spectrum.

Based on existing research, gene -type 4 European poultry -like pig -like influenza viruses can combine human saliva receptors to enable the virus to be effectively copied in human airway epithelial cells. The sequence analysis shows that some of the gene -type 4 viruses reported before and the Eurasian poultry H1N1 virus separated from this study may have a common ancestor, indicating that the genome and its reorganization of popular potential will be further evaluated.

In addition, human infection related to poultry type A influenza virus contains internal genes from poultry H9N2 viruses, indicating that the internal genes of H9N2 virus may help transmission of human and animals, indicating that the virus strain has the possibility of transmission of human and livestock.
