The situation regarding avian influenza continues to evolve in Europe and globally, with reports of new outbreaks in birds and occasional infections in mammals. Sporadic human infections have been reported in countries outside the EU, while the risk to the public in the EU remains low.
Between 3 December 2022 and 1 March 2023 highly pathogenic avian influenza (HPAI) A(H5N1) virus, clade 2.3.4.4b, was reported in Europe in domestic (522) and wild (1,138) birds over 24 countries. An unexpected number of HPAI virus detections in sea birds were observed, mainly in gull species and particularly in black-headed gulls (large mortality events were observed in France, Belgium, the Netherlands, and Italy).
No human infections with avian influenza virus were reported in the European Union/European Economic Area (EU/EEA) in 2021. Sporadic human infections with avian influenza virus A(H5) (including A(H5N1) and A(H5N6)), A(H9N2) and A(H10N3) infection were reported globally in 2021.
In February 2023, Cambodia reported a family cluster in Sithor Kandal district, Prey Veng province, with two people (a girl and her father) infected with avian influenza A(H5N1) virus.
