The G4 virus has been in the pig population since 2013, and research on vaccines and diagnostic kits is under way.

Swine flu virus is an important human and animal disease.
, the Proceedings of the American Academy of Sciences published an online research paper by a Chinese research team, co-authored by Liu Jinhua, professor of animal medicine at China Agricultural University, and Gao Fu, academician of the Chinese Academy of Sciences and director of the Chinese Center for Disease Control and Prevention.
paper says a swine flu virus, the G4 virus, which could trigger a pandemic, has been found in pigs.
the news caused widespread concern.
will the swine flu virus cause a pandemic? "Don't panic, the virus is not new, has been in pigs for many years, and no G4 virus has formed human-transmitted outbreaks.
" Liu Jinhua said in an interview with Science and Technology Daily, "So far, no pig farm practitioners have been found to have cluster edion, indicating that the virus to people only show a limited number of sexual infections, has not yet formed an effective ability to break through the inter-species barrier to infect people."
"The G4 virus has appeared in 2013, and is gradually spreading in pigs, is there a danger to this new influenza virus?" "What needs to be said is that the G4 influenza virus reported in the study is not a new virus, the virus has been around since 2013, and we have found through continuous follow-up monitoring that this type of virus is gradually becoming endemic in pigs."
"G4 virus epidemic in pigs increases the chances of human exposure to or infection with the virus.
paper notes that some pig farmers have detected antibodies.
"But this is only a serological monitoring data, not from these pig farm staff to isolate the G4 virus, and because the population infected with seasonal influenza virus or influenza vaccine, will have some antibody cross-reaction effect, so the real infection value should be lower than the serum monitoring value."
," Liu Jinhua said.
study also found that the g4 swine flu virus's internal genes are mostly derived from the pdm/09 H1N1 virus, compared with the traditional G1 virus in pigs, so the G4 virus may easily infect people after adaptive mutation.
compared with the new coronavirus, Liu Explained that the G4 virus is very different from its.
" new coronavirus is a new virus, people have never faced before, people know the characteristics of the new coronavirus, especially the pathogenesis, immune mechanism is still very little.
," he said.
current vaccine and diagnostic kit research is under way that no one can accurately determine when the next influenza pandemic will occur, but we should always be alert to the occurrence and epidemic of influenza. "In terms of public health security, the threat of the G4 influenza virus is present and therefore needs to be alerted to us,"
.
," Liu Jinhua said.
influenza virus is a kind of human-animal co-infectious disease, mastering the prevalence of virus in animal host is important for preventing and controlling the epidemic between virus animals and cross-infection population.
the occurrence of influenza A(H1N1) in 2009 not only caused serious economic losses to the global pig industry, but also endangered human public health.
after 2009, a number of research teams at home and abroad found that the human epidemic of the pdm/09 H1N1 influenza virus back to pigs and the swine flu virus circulating in pigs continue to occur gene rearrangement, and some re-emissionvirus has been infected with human events.
"In terms of influenza, influenza is a common pathogen in the population, with seasonal flu epidemics almost every winter and spring."
especially since the first pandemic flu occurred in 1918, people have accumulated four experience in the fight against influenza, not only have vaccines, but also special drugs, and more importantly, have a good monitoring network, once the new influenza virus epidemic will be immediately monitored, human influenza vaccine production technology is also very mature, can be developed quickly.
," Liu Jinhua said.
in the past ten years, Liu Jinhua's team has been carrying out the investigation of the swine flu virus.
" our team has not only carried out research on the continuous monitoring and virus characteristics of influenza viruses in pigs, but also has been studied for vaccine and diagnostic kits to prevent and control the occurrence of diseases in pigs.
," Liu Jinhua revealed.
