Chinese and American researchers have discovered a new type of dog flu virus

Swine flu virus H1N1 has spread to dogs and recombines with other virus genes in dogs, and the number of influenza virus subsypes in dogs is increasing, according to a study published In the American journal
.
and pigs are the main hosts of the genetic diversity that cause influenza viruses, while dogs and horses carry fewer types of influenza A viruses and are rarely contagious, the researchers said. Previous studies have found that the main types of influenza A viruses prevalent among dogs are H3N8 and H3N2.
between 2013 and 2015, researchers at Guangxi University in China and the Mount Sinai Icahn School of Medicine in the United States extracted and sequenced 16 strains of influenza virus in dogs living in Guangxi, China, and found genetic fragments of three swine flu viruses. The swine flu virus H1N1, which is transmitted to dogs, has been genetically recombined with the dog flu virus H3N2, and three new dog flu viruses have emerged.
Garcia-Sassott of the Mount Sinai Icahn School of Medicine, who was involved in the study, said the flu virus in dogs is diverse and the virus genes can be combined, which can pose a risk to humans.
say human serum will be used in the future to determine whether the body is immune to the dog flu virus. Garcia-Saste says that if people are immune, the risk of new virus transmission is less.
Dugard, professor of virology at the University of Edinburgh in the UK, commented that influenza viruses from other animals can spread to dogs, which does not mean that they will necessarily spread between dogs and that they are difficult to spread to other animals. There have been no cases of human infection with these dog flu viruses. (Source: Xinhua News Agency Zhou Zhou)
