Influenza A virus subtype H10N7 (A/H10N7) is a subtype of the species Influenza A virus (sometimes called bird flu virus). H10N7 was first reported in humans in Egypt in 2004.[1] It caused illness in two one-year-old infants, and residents of Ismailia, Egypt; one child's father, and a poultry merchant.[2]

The first reported H10N7 outbreak in the US occurred in Minnesota on two turkey farms in 1979 and on a third in 1980. "The clinical signs ranged from severe, with a mortality rate as high as 31%, to subclinical. Antigenically indistinguishable viruses were isolated from healthy mallards on a pond adjacent to the turkey farms".[3]
The Influenza A (H10N7) virus was also held responsible for an increased mortality of harbour seals (Phoca vitulina) in Europe in 2014.[4] First cases were reported in spring 2014 in Sweden and subsequently spread to Denmark.[5][6] Within a few months the virus spread to the Wadden Sea area of Germany and the Netherlands causing the death of about 10% of the local harbour seal population.[7]
