The Centers for Disease Control and Prevention announced Monday that a person in Texas has tested positive for highly pathogenic avian influenza, otherwise known as H5N1 bird flu.

"This person had exposure to dairy cattle in Texas presumed to be infected with HPAI A(H5N1) viruses. The patient reported eye redness (consistent with conjunctivitis), as their only symptom, and is recovering," the CDC said in a statement. "The patient was told to isolate and is being treated with an antiviral drug for flu."

The CDC said this is the second case of a human testing positive for H5N1 in the United States, after a previous case was observed in Colorado in 2022.
