There were 12 wild birds either found dead or dying with H5N1 during January to March 2007 in Kowloon (Top). Consequently, the government conducted a special cleansing operation on 2/3/2007 in Sham Shui Po and Mongkok. After the cleansing operation, only one dead bird was found in Hung Hom over the following two months (Bottom). While the cleansing operation might have appeared effective, other factors like migration of birds could have contributed to the phenomenon.

由零七年一月至三月期間，九龍撿獲十二隻感染H5N1的病或死鳥(上圖)。有見及此，三月二日政府有關部門聯合在深水埗和旺角進行特別清洗行動。在往後的兩個月，只有一隻受感染的死鳥在紅磡被發現(下圖)。清洗後病或死鳥數目似乎大大減低，但在分析時，要考慮其它如雀鳥離去等因素。

Avian influenza 禽流感

What is avian influenza? 什麼是禽流感?

Avian influenza (“bird flu”) is an infectious disease of birds caused by type A strains of the influenza virus. The infection can cause a wide spectrum of signs and symptoms in birds, ranging from mild illness, which may be passed unnoticed, to a rapidly fatal disease. Avian influenza has caused widespread epidemics in bird population in many parts of the world.
禽流感是一種由甲型流感病毒所引起的禽鳥傳染病。受感染的禽鳥可能呈現輕度癥狀，部份或會出現急性致命的疾病。禽流感已逐漸演變成在全球各地禽鳥中散播的疫症。

Is human susceptible? 人會感染禽流感嗎?

Avian influenza has remained a disease of the bird populations. So far there is no solid proof of efficient human to human transmission. A majority of the infected persons have a history of close contact with infected birds through, for example, slaughtering.
到目前為止，禽流感仍主要是禽鳥的疾病，並未有實證顯示病毒經人傳人快速擴散。在已知的人類感染禽流感個案當中，大部份曾經與受感染禽鳥有緊密接觸，例如屠宰等。

Vaccine? Prevention? 如何預防？

Currently effective vaccine against avian influenza is not available. Preventive measures include maintaining good personal hygiene, proper slaughtering procedures and handling of poultries, avoiding handling of wild birds. Suspected cases of infected birds should be promptly reported to the authorities.
現時還沒有有效的預防禽流感疫苗。預防措施主要包括保持個人衛生、採取適當屠宰程序及處理家禽程序和避免接觸野生雀鳥等。假使發現疑似感染H5N1或已死的雀鳥，應盡快告知有關當局。
