"Latest human H5N1 bird flu case in US is 1st to cause respiratory symptoms"

Our introduction to May 11's "The first case of a walrus dying of bird flu registered on Svalbard"

Bird to mammal (including humans) Avian Flu transmission has been happening for years [centuries, millennia?]. It's mammal to mammal H5N1 spread that would get frightening. And especially respiratory transmission. That said, it doesn't sound like the Walrus got it from another mammal or that it became a buffet for a polar bear or ten....

This infection, tied to an ongoing outbreak in cows, is the first in the U.S. to cause respiratory symptoms, but not the first H5N1 case in the world to do so.

A third human case of bird flu has been linked to the ongoing outbreak in cows on U.S. dairy farms — and this one came with respiratory symptoms, such as cough, the Centers for Disease Control and Prevention (CDC) reported May 30.

Officials first became aware of bird flu spreading among U.S. dairy cows in March, and since then, the viral disease has been detected among cattle on farms in nine states. The type of bird flu spreading is known as H5N1, which has sporadically infected individual humans in the past but has never spread widely from person to person. However, these rare human infections can sometimes be fatal, and there's concern about the virus picking up the necessary mutations to spread easily through the populace.

Prior to the outbreak in cows, only one person in the U.S. had ever been infected with H5N1, as far as we know. Now, since the outbreak began, three people have likely been infected via exposure to sick cows. The first person infected by a cow was in Texas, and the second was in Michigan; both are dairy-farm workers and developed only eye infections from the virus before recovering....
