How HPAI cases are identified and announced:

There are several steps involved in confirming a poultry flock is positive for a highly pathogenic strain of avian influenza. Here is an outline of the process, which includes timing of public notification:

1.     A poultry producer or backyard flock owner notices unexplained death loss or other signs of illness in his/her birds.
2.     The individual notifies their veterinarian or an animal health official.
3.     Samples are collected from the birds on the premises.
4.     Samples are submitted to the North Dakota State University (NDSU) Veterinary Diagnositc Laboratory for preliminary testing.
5.     The NDSU Veterinary Diagnositc Laboratory determines if the samples are positive for an H5 or H7 influenza virus.
   • If samples are positive for an H5 or H7 virus, they are considered as presumptive positives and are forwarded to the National Veterinary Services Laboratory (NVSL) in Ames, Iowa. NVSL is the only laboratory in the United States that is authorized to officially confirm the presence of a HPAI and identify the specific strain of virus.
6.     Once NVSL confirms HPAI, the USDA posts updates on its website.
