Epidemiological commentsThe original report submitted on 27 November 2019 for highly pathogenic avian influenza (HPAI) with OIE reference number 32493 was deleted and replaced with the report number 32513 for low pathogenic avian influenza on 29 November 2019. The latter report and correspondent follow-up report No. 32654 were subsequently deleted on the 20 December 2019 and replaced by the current immediate notification. These changes were done due to the intravenous pathogenicity index (IVPI) laboratory analysis which confirmed the H5N6 as highly pathogenic avian influenza.
