This study was conducted to quantify the infectivity of PED at the farm level in the initial phase of an epidemic in Kagoshima Prefecture, the largest swine producing area in Japan. A compartmental model was developed with the following five components of farm status according to the situation of within-farm PED infection : susceptible with no infected pig (S) ; exposed with at least one infected pig but no pig showing clinical symptoms (E) ; infectious with at least one pig showing symptoms, but the farmer has not yet reported it to the veterinary authorities, whether intentionally or unintentionally (In) ; infectious with pigs showing symptoms, and recognized by the veterinary authorities as an infected farm (Id) ; and recovered with all pigs having recovered from PED (R). Parameters were solved to maximize the likelihood of daily new cases and cumulative number of recovered farms modelled given the actual numbers during the first 40 days of the epidemic using data provided by the Kagoshima Prefectural government. The incubation period was set at two days, and the first case of each farm was assumed to be reported on the next day to the authority. The basic reproduction number R0 was calculated using the next generation matrix. As results, the infectious period and R0 were estimated to be 54.4 days and 5.39, respectively. In conclusion, inter-farm infectiousness was very high during the initial phase, and the long infectious period at the farm level, in addition to the common source infections already reported, contributed to the rapid spread of the disease.","subitem_description_type":"Abstract"},{"subitem_description":"日本の養豚業は2013年に国内に侵入した世界的な豚流行性下痢(PED)の流行により甚大な被害を被った。本研究は,国内最大の養豚地帯である鹿児島県にて発生したPED流行初期における農場レベルでの感染力を定量化するために実施された。農場内感染状況により農場を以下の5つのコンパートメントに分けたコンパートメントモデルを作成した:感染豚がいない感受性期(S) ; 少なくとも一頭の感染豚がいるが一頭も症状を呈していない暴露期(E) ; 少なくとも一頭の豚が症状を呈しているが,意図的にあるいは意図せずにまだ獣医当局に報告されていない感染性期(In) ; 症状を呈している豚がおり,獣医当局に感染農場として認識されている感染性期(Id) ; 全ての豚がPEDから回復した回復期(R)。パラメーターは,鹿児島県から提供された流行開始から40日間の実際のデータを基に,日ごとの新発生数と累積清浄化農場数の最尤推定により導出した。潜伏期間は2日間,獣医当局へは発生翌日に通報されるものと仮定した。基本再生産数R0は次世代行列を用いて計算した。結果として,感染性期間およびR0はそれぞれ54.4日と5.39と推定された。まとめとして,流行初期の農場間感染力は非常に高く,これまですでに報告されている共通感染源感染に加えて農場の感染性期間の長期化が本病の迅速な拡大の原因となっていたことが明らかとなった。","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"","nameIdentifierScheme":"ISNI","nameIdentifierURI":"http://www.isni.org/isni/"}]}],"familyNames":[{"familyName":"MAKITA","familyNameLang":"en"},{"familyName":"蒔田","familyNameLang":"ja"}],"givenNames":[{"givenName":"Kohei","givenNameLang":"en"},{"givenName":"浩平","givenNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"4758","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9430","nameIdentifierScheme":"教員総覧","nameIdentifierURI":"https://www.rakuno.ac.jp/archives/teacher/9430.html"}],"names":[{"name":"MAKITA,
