    Epidemiology
    Source of the outbreak(s) or origin of infection
    • Unknown or inconclusive
    Epidemiological comments The comparative analysis of the obtained nucleotide sequence of the H gene fragment revealed that the isolates belong to an Asian genetic lineage of highly pathogenic avian influenza (lineage A/Gs/Guangdong/96, Clade 2.3.4.4.). Based on the H gene fragment the avian influenza A virus (H5) sequences were isolated in several RF Subjects in 2016-2017. And the avian influenza A virus (H5) sequences were isolated in South-East Asia in 2013-2014, as well as in Europe and Iran in 2017.
