Avian influenza has been around for a long time, and recent research on it has made further discoveries. According to CCTV reports, data from Japan’s Ministry of Agriculture, Forestry and Fisheries show that during the 2022-2023 bird flu season, Japan encountered the most serious bird flu epidemic on record.A total of 84 bird flu outbreaks were reported, and more than 17 million poultry were culled., resulting in a shortage of egg supply.
Recently, a survey conducted by Kyushu University in Japan showed thatFlies may be involved in spreading avian influenza virus.
Researchers captured hundreds of blowflies near chicken farms in Demizu City, Kagoshima Prefecture, where multiple bird flu outbreaks occurred at the end of last year, and conducted detailed analysis. The results showed that at the location with the highest virus detection rate, about 15% of blowflies had guano containing avian influenza viruses in their digestive tracts, and the virus still maintained its ability to infect.
It is said that blowflies often gather in bird droppings and animal carcasses during the egg-laying period in winter because they need nutrition. They are also common around chicken houses, and chickens also have the habit of preying on flies.It may be that flies brought the avian influenza virus in feces or carcasses into the poultry house, causing serious infection.
This discovery also provides new ideas for the prevention and control of avian influenza. Before this, people generally blocked the circulation of sick poultry, and also set up anti-bird nets, etc., but still could not provide an effective prevention plan. This discovery provides more inspiration.Use insect netting to deal with flies, which may have a good effect on reducing the spread of avian influenza.
