全球非洲豬瘟疫情形勢十分嚴峻，2019年以來共29個國(guó)家/地區報告了技近新發(fā)或正在流行的疫情，是窗非洲豬瘟的防控備受全世界關注。爲議化全面(miàn)了解非洲豬瘟病毒（ASFV）特性，概述了近年來中明對(duì)ASFV病原學(xué)特性和流行病學(x國算ué)特點的一些新認識：ASFV對(duì)外界抵抗力較強，月商但怕幹燥、高溫、強酸和強堿；除家豬、野豬、數木軟蜱外，蒼蠅也可能(néng)扮火為演著(zhe)儲存宿主的角色；污染的飼料、飲用水也是ASFV的重要傳染源聽做，其中飲水造成(chéng)ASFV感染的劑量更低，熱唱二者的風險點相差1萬倍，防控時(shí)要高度重視飲用水湖雪；非洲豬瘟傳播途徑較多，但肉制品、環境、車作設備或車輛、人員是傳播的重要風險因拿物素，管理好(hǎo)其流動是防控的關鍵。本文對(duì)于識别非洲豬瘟的又上所有潛在傳染源和傳播途徑，以便采取更有效的金中防控措施具有參考意義。
