Avian influenza, also known as bird flu, has been detected in Canada geese in Jefferson County — now one of 10 Kentucky counties where infections have been found, as cases continue to surge across the U.S.

State officials say the highly pathogenic avian influenza – more commonly known as bird flu – is widespread in much of the state.

The discovery of bird flu in the San Mateo backyard flock prompted health officials to remind people to take biosecurity measures.
