AI results complementing the 2021 Annual Report on surveillance for Avian Influenza in poultry and wild birds in Member States of the European Union - Portugal

This dataset contains the results of the EU co-funded surveillance activities conducted in 2021, which consisted of: Serological surveys to monitor the circulation of AIV subtypes H5 and H7 in poultry (active surveillance). These surveys should preferentially target poultry species or production systems with increased risk for introduction of avian influenza (AI). Passive surveillance aiming at the virological detection of AI in wild birds found dead or moribund.本数据集收录欧盟联合资助的2021年度监测活动的相关成果，该监测活动包含以下两项内容：一是针对家禽中禽流感病毒（Avian Influenza Virus, AIV）H5、H7亚型传播循环开展的血清学调查，属于主动监测范畴。此类调查应优先针对存在禽流感（Avian Influenza, AI）传入风险升高的家禽物种或养殖生产系统实施；二是针对死亡或濒死野生鸟类中的禽流感开展病毒学检测的被动监测工作。
