為評估傳染性造血器官壞死病病毒（infectious haematopoietic necrosis virus，IHNV）隨國際貿易傳入我國的風險，按照世界動物衛生組織（WOAH）動物衛生風險評估框架，從危害識別、風險評估及風險管理3個方面開展風險分析。結果顯示：IHNV隨活易感魚類（包括親魚、魚卵和魚苗）和鮮活餌料魚類（野雜魚）傳入的風險為“高”；隨非易感魚類及運輸活魚的水、包裝、運輸工具和用具等傳入的風險為“很低”；隨食用易感魚類（包括活的、冷凍的、冰鮮的以及魚肉）和易感魚加工產品傳入的風險為“可忽略”。根據以上風險評估結果提出相應風險管理措施：不從疫區進口高風險產品，低風險產品可以自由貿易，對來自疫區的非易感魚類和運輸活魚的水、包裝、運輸工具和用具實施消毒。

Analysis on the Entry Risk of Infectious Haematopoietic Necrosis

In order to evaluate the entry risk of infectious haematopoietic necrosis virus（IHNV）into China with international trade，hazard identification，risk assessment and risk management concerning the disease were analyzed according to WOAH entry risk assessment framework. The results showed that the entry risk of IHNV accompanying with live susceptible fish（including parent fish，fish eggs and fries）and live fish for baits（wild miscellaneous fish）was“high”；that with non-susceptible fish as well as water，packaging，means of transport and appliances for transporting live fish was“very low”；and that with susceptible fish for human consumption（including live，frozen or chilled fish and fish meat）and processed products of susceptible fish was “negligible”. Based on the results of above risk assessment，corresponding risk management measures were put forward，such as，except the products at low risk，those at high risk should not be imported from IHNV infected zones，all non-susceptible fish from infected zones as well as the water，packaging，means of transport and utensils for transporting live fish should be disinfected.
