The Centers for Disease Control and Prevention (CDC) issued a health alert Friday to inform clinicians, state health departments and the public of a case of avian influenza — aka bird flu — in a person who had contact with dairy cows in Texas.
A farmworker on a commercial dairy farm in Texas developed conjunctivitis last week, and subsequently tested positive for bird flu, the agency said.
The positive bird flu diagnosis came after milk from dairy cows in Texas and Kansas tested positive for the disease.
The infection follows a 2022 case in Colorado, and is the second person to test positive for the bird flu virus in the U.S.
While the CDC said that the current risk these viruses pose to the public remains low, people who are regularly around infected birds, cattle, or other animals are at higher risk of infection and should take appropriate precautions.
Since 1997, more than 900 sporadic human cases of bird flu have been reported in 23 countries.Â
The CDC said that more than half of the approximately 900 cases resulted in death.Â
While the fatality rate for humans is high, there is a near 100% fatality rate for birds with the disease.Â
