An outbreak of avian poxvirus infection was confirmed in Japanese cormorants used for "cormorant fishing" in July 2017 in Yamanashi Prefecture. Also in July 2019, another outbreak of this disease was confirmed in a different group of birds. In both cases, the typical lesions in pox were observed visually in the beak and eyelids. As results of virological examination, avian poxviruses were isolated from samples in both cases.
