A man in Colorado has been diagnosed with avian influenza but the chance of the virus spreading is low, according to the Centers for Disease Control and Prevention. 

Avian influenza, more commonly known as bird flu, is a virus that impacts poultry and birds but can sometimes spread to humans.

The pathogen is passed to humans and spread through an infected bird's saliva, mucus or feces.

The CDC says the infected man had direct exposure to poultry with H5N1 bird flu. The patient reported fatigue for a few days as their only symptom and has since recovered, according to the CDC.
