The recent report of a highly pathogenic virus of subtype H7 (N to be identified) shows the risk for the region, especially at this time of the year (near spring bird migration).
Interestingly, surveillance in the wild had previously shown circulation of H5N2, also a HPAI strain which somehow denied claims that highly pathogenic viruses do not persist in wild birds.
This time: not only appears a different subtype, but it appears directly in poultry affecting breeder where there is usually greater biosecurity.
Some specialists in the United States have come to express the term "seasonally endemic" to refer to AI in allusion that HPAI cannot continue to be considered exotic.
