Resources and information about highly pathogenic avian influenza (HPAI), the disease caused by infection with avian (bird) influenza (flu) Type A viruses.
Since December 2014, USDA has confirmed several cases of highly pathogenic avian influenza (HPAI) H5 in the Pacific, Central, and Mississippi flyways (migratory bird paths). The disease has been found in wild birds, as well as in a few backyard and commercial poultry flocks. The symptoms can vary from a mild disease with little or no mortality to a highly fatal, rapidly spreading epidemic (highly pathogenic avian influenza) depending on the infecting virus strain, host factors, and environmental stressors.

What Are We Doing?
Penn State faculty members and extension educators are serving on a statewide avian flu task force chaired by Pennsylvania Agriculture Secretary Russell Redding. The group is developing action plans and procedures related to biosecurity; depopulation and disposal of infected flocks; issues relevant to small or backyard flocks; alternatives for youth poultry exhibitors at county fairs and other shows where live birds have been prohibited; and other concerns.
In addition, Penn State's Animal Diagnostic Laboratory routinely tests poultry samples for the presence of avian flu viruses and other disease pathogens. In the past, rapid diagnosis by the lab has enabled the state to contain avian flu outbreaks and limit costs.
