Highly pathogenic avian influenza
高致病性禽流感


These maps show the worldwide distribution of highly pathogenic avian influenza (HPAI), serotype H5N1 reported in human and animals from 2004- 2008. Human cases are expressed in graduated symbols, and animal outbreaks are represented in graduated colour.

Initially, animal outbreaks were reported largely from East Asia and South East Asia, when concurrently Thailand and Vietnam reported human infect cases of HPAI serotype H5N1. The animal outbreaks then gradually spread to Russia and some parts of Europe, while human cases remained localised in Asia and South East Asia. In 2006, H5N1 animal outbreaks were first reported in Africa, and the virus had almost intruded the entire Europe, including Scandinavian countries like Denmark and Sweden. In 2007-2008, animal outbreaks continued across Asia, Europe and some parts of Africa. Between 2006 and 2008, human cases were reported across East Asia, South East Asia, South Asia and Africa..

地圖顯示二零零四年至二零零八年全世界高致病性禽流感血清分型H5N1人類感染個案和動物感染爆發數字。人類個案數值區間顯示為漸變圖示,而動物爆發數值區間顯示為漸變顏色。

在這五年期間,動物感染爆發始於東亞及東南亞地區,當時泰國和越南均有人類感染高致病性禽流感H5N1個案。其後動物爆發續漸擴散到俄羅斯和歐洲某些國家,而人類感染個案在亞洲及東南亞地區持續發生。二零零六年,非洲首次錄得動物H5N1爆發,病毒亦入侵歐洲多國包括北歐國家如丹麥及瑞典。二零零六至二零零八年間,動物感染在亞洲、歐洲和部份非洲國家爆發。在這期間,人類個案則在東亞、東南亞、南亞和非洲續有呈報。
