Global Avian Influenza Viruses with Zoonotic Potential situation update
28 December 2023, 08:30 hours; Rome
Overview
This update covers avian influenza viruses (AIV) with zoonotic potential occurring worldwide, i.e. H5Nx, H7Nx high pathogenicity avian influenza (HPAI) viruses and H3N8, H5Nx, H6N1, H7Nx, H9N2, H10N3, H10N7, H10N8 and H11 low pathogenicity avian influenza (LPAI).
Specific information is available for Avian Influenza A(H7N9) virus viruses and Sub-Saharan Africa HPAI in related FAO Avian Influenza situation updates.
HPAI outbreaks in animals officially reported since last update (28 September 2023): in total, 715 outbreaks/events have been reported in four geographic regions caused by H5Nx (101), H5N1 (580), H5N5 (2), H5N6 (28), H7N6 (2) and HxNx (2). (see Table 1 for details)
LPAI events in animals officially reported since the last update (30 November 2023): 15 new events were reported.
Number of human cases officially reported since last update (30 November 2023): 3 new events were reported.1,2

Data was retrieved from WOAH WAHIS portal, government websites. Data cut off time: reported on 28 December 2023 8:30 CEST. $:estimate.
§ During the reporting period, China (Hong Kong SAR) also reported two H5 in Eurasian wigeons and three H5N1 detections in a Pin-tailed snipe and Eurasian teals (pathogenicity unknown).
The full list of bird and mammalian species affected by H5Nx HPAI are available HERE.
Notes: Only those reporting events in animals since 24 August 2023 are listed in the table, those reporting for the first time since 1 October 2023 in orange. Codes: D:domestic, C:captivity, W:wild birds, F: Feral, E:Environment, M: mammalian species other than humans, example: W123 indicates 123 wild birds affected. EA: Fully Eurasian; rEN: Reassortment Eurasian and North American.
