Highly pathogenic avian flu, H5N1 Bird Flu, has infected a worker in Texas, only the 2nd known human infection in the U.S. since the pandemic began, in 2022.
This directly follows an outbreak of H5N1 in Texas dairy cattle that has already spread to other states. Already, billions of birds have died in this pandemic, both domestic chickens & turkeys, as well as wild birds. It has not yet mutated into a form that is transmissible from human to human. However, gaining the ability to transmit between mammals, particularly farm animals, could be a step in that evolutionary direction. And its case fatality rate may be as high as 50%
