Muchidzidzo ichi, H4n6 Subtype AIV yaive ichiparadzaniswa kwenguva yekutanga kubva kune faecal samples yemusango gomba madhiri (anas plotyrhynchos) muIsrael. Phylogenet mhedzisiro yeHA uye maini maGenera anoratidza kuti iyi madhiri ane hukama zvakanyanya neEuropean neAsia isopes. Sezvo Israeri iri pamwe neyeMiddle arctic-African migratory nzira, inofungidzirwa kuti dambudziko raigona kuunzwa ne shiri dzinofamba. Nyanzvi dzePhylogenetic yeMukati maGomeni Iyi H4n6 Subtype yeAIV ine chiyero chepamusoro, chinogona kukanganisa nguruve dzine hutano uye dzinosunga nzvimbo dzevanhu, uye zvinogona kukonzera chirwere cheziso mune ramangwana.
