A study by a research team at the Japanese University of Tokyo, Japan, confirmed for the first time that H7N9 virus virus can spread through wreaths. Experts in charge of the study are concerned that the virus mutated into a new type of influenza virus that could trigger a global epidemic and called for an increase in alert.

The research team, led by Professor Hegang Ioshihiber from the University of Tokyo's Institute of Medical Sciences, after infection with the bird flu virus H7N9, revealed that the virus can be mixed in droplets with sleds and spread to the outside of the body. In order to prevent contamination of other healthy ferments, the researchers separated two ferrets from the cages by about 7 cm. After four days, healthy ferrets are still infected and detected at a distance of 80 cm. Virus.
Prior to this, when avian influenza viruses are infected with mammals, droplet infection is almost completely ignored. This is the first time that a strain of avian flu virus can pass through droplets. Researchers say that if the avian influenza virus genes mutate several times, a new type of influenza virus will be produced that will become more susceptible to human infection.
Professor He Gang warned that the bird flu H7N9 is likely to cause a global epidemic, and it is necessary to raise alertness and further research is needed. The H7N9 avian influenza virus confirmed the first case of human infection in the world in China in 2013. So far, more than 1,500 people have been infected in areas in China, mostly from birds to humans.
Hegang Iiiu specializes in the study of influenza virus and Ebola virus and is the winner of the German Nobel Medicine Prize, Robert Coho. He copied the Spanish influenza virus from 1918 to cause panic, and then made a more powerful H1N1 influenza virus that broke out in 2009, which was criticized by the scientific community.
In addition, Secretary of Food and Health of Hong Kong, Mr. Chan Chan-chu, stressed that the risk of bird flu has always existed. He said Bailiang, director of the University of Hong Kong's Center for Infectious and Infectious Diseases, said dozens of virus samples were highly pathogenic in human cases of H7N9 infection throughout China, causing serious infections in humans or birds. However, he pointed out that the spread of avian influenza virus through droplets is not new information. At this stage, the pandemic risk assessment of avian influenza is still low.
