A highly pathogenic avian influenza confirmed in four states can be very deadly for birds, but a Kansas State University poultry expert says humans don’t need to worry about their own health or contaminated poultry products.

The US Department of Agriculture Animal and Plant Health Inspection Service has confirmed the presence of H5N2 avian influenza in Kansas, Missouri, Minnesota and Arkansas. This strain is considered highly pathogenic in birds with a high mortality rate.

The Centers for Disease Control considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry to be low. No human infections with the virus have been detected at this time.
