The Centers for Disease Control and Prevention said in a summary on Friday that it is preparing for the “possibility of increased risk to human health” from bird flu following an outbreak among dairy cows and two confirmed human cases.
However, the federal health agency also said the risk of bird flu, also known as avian influenza, to people in the U.S. is currently low and there is no evidence of person-to person transmission in the U.S.
Federal and state public health officials said in late March they were investigating an illness among primarily older dairy cows in Kansas, New Mexico and Texas and causing symptoms including decreased lactation and low appetite.
