Rapid Risk Assessment, 25.09.2023
Between 1 July and 31 August 2023, an HPAI H5N1 outbreak was detected in geese in the north of the district of Schleswig-Flensburg in Schleswig-Holstein in Germany on 7 July, which is presumably due to an entry by wild birds. As expected, the number of cases in wild birds decreased in July (n=83) and August (n=17). Most cases were reported from the coastal federal states of Lower Saxony (n=56), Schleswig-Holstein (n=17) and Mecklenburg-Western Pomerania (n=8), followed by North Rhine-Westphalia (n=8), Saxony (n=4), Bavaria, Berlin, and Hamburg (2 each) and Saxony-Anhalt (n=1) (Tab. 1, Fig. 1). Similar to the previous months, the reports most frequently concerned gulls (n=45) and terns (n=42), birds of prey (n=2) and only occasionally alcids (n=2), wild geese (n=2) and gannet (n=1) (Tab.1).
