TOPEKA — Kansas is suffering from the worst outbreak of highly pathogenic avian influenza in the country, with nearly 414,000 birds affected, according to the U.S. Department of Agriculture.
HPAI, an umbrella term for avian influenza that includes highly contagious strains such as H5 and H7, is considered a low public health risk, although it can pass to humans through birds and dairy products from infected cattle, according to the U.S. Centers for Disease Control and Prevention.
“H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows with sporadic human cases in U.S. dairy and poultry workers,” according to CDC.
As of Friday, there are four affected commercial flocks and six affected backyard flocks reported in Kansas, according to the U.S. Department of Agriculture. Avian influenza kills almost 100% of the birds it infects.
The bulk of the infected birds, about 380,000, in Kansas were reported to be in a commercial operation in Pottawatomie County, USDA reports said.
In a map highlighting outbreaks across the nation, Kansas is the only state showing the most severe reports during the past 30 days. It is followed by Indiana, with about 87,000 birds affected, including two commercial flocks and five backyard flocks.
Kansas has not had a reported instance of avian bird flu in a human, according to CDC records. Since 2024, there have been 74 reported bird flu cases in humans and two deaths.
