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]
