This marks the state’s first human case of bird flu. The Oregon Health Authority said the case is linked to an outbreak in chickens at a commercial egg farm in Clackamas County last month.

Health officials have announced six more H5N1 bird flu infections in humans: five in California and the first known case in Oregon.

The US western state of Oregon is the latest to confirm a case of avian influenza in a human, according to a release from the state Health Authority. The transmission was confirmed by the Centers for Disease Control and Prevention.
