Due to the decrease in air passengers from China due to the spread of the new coronavirus infection, the risk of invasion of the infectious disease of pigs, African swine fever, which continues to be prevalent in Asian countries such as China, has been significantly reduced. Tokyo
It was found in the research of Professor Katsuaki Sugiura of the Graduate School of Agriculture and Life Sciences, University.
東京大学によると、杉浦教授らは以前に開発していた侵入リスク評価モデルを使って新型コロナで中国からの航空旅客とレストランの営業時間短縮による食品廃棄物が減少している現状を踏まえ、月間侵入確率を計算した。その結果、1月は4.2％だったが、それ以降は2月0.45％、3月0.03％、4月0.0002％、5月0.00005％、6月0.0009％と中国からの航空旅客が減少するのに伴い、大幅に低下していた。
Calculating the situation in 2019 when tourists from China were seen nationwide, the monthly intrusion probability was around 4%, so the intrusion risk was greatly reduced from 10/1 to 7 / 1.Professor Sugiura and colleagues conclude that the decrease in air passengers from China and the decrease in food waste had an impact.
Classical swine fever is an infectious disease that spreads to pigs and wild boars from the African swine fever virus, and does not infect humans. Since invading China in August 2018, it has spread from China to Asian countries, and the risk of invasion into Japan is increasing.Infection spreads by bringing in pork products by air passengers and feeding leftover food mixed with virus to pigs.
