According to a study published on June 5 in the online journal of Microbiology of the United States, H1N1 has been transmitted to dogs and recombined with other virus genes in dogs. Influenza virus subtypes in dogs are increasing. Is this kind of infectious disease harmful? Will it lead to death?
Birds and pigs are the main hosts of genetic diversity, while dogs and horses carry fewer types of influenza A and rarely infect people, the researchers said. Previous studies have found that H3N8 and H3N2 are the main types of influenza A virus circulating among dogs.
From 2013 to 2015, researchers from Guangxi University of China, Mount Sinai Medical College and other institutions extracted 16 influenza virus strains from dogs living in Guangxi, China, and sequenced them. Three gene fragments of swine influenza virus were found. Three new canine influenza viruses have been produced by recombination of H1N1 and H3N2.
According to Adolf middot Garcia Sutter of Mount Sinai Medical College, who participated in the study, the influenza virus in dogs has a diversity, and the virus genes can be combined with each other, which may cause risks to human beings.
In the future, human serum will be used to determine whether the human body is immune to the dog flu virus, the researchers said. Garcia - saster said that if people have immunity, the risk of new virus transmission to people will be smaller.
Professor of Virology at the University of Edinburgh, Paul Middleton digard, commented that influenza viruses from other animals can be transmitted to dogs, which does not mean that these viruses are bound to spread between dogs, and these viruses are difficult to transmit to other animals. So far, no one has been infected with the dog flu virus.
