A switch from avian- to human-type receptor specificity is considered a major risk factor for transmission in humans (33, 35, 64). For this reason, our observation that the single Texas H5 HA Gln226Leu mutation can switch receptor specificity is a clear concern. The bovine airway and mammary gland epithelium have predominantly avian-type and, to a lesser extent, human-type receptors (65, 66), which provide little selective pressure for acquiring human-type receptor specificity. However, H5N1 infection of dairy workers, who have human-type receptors (34), provide selective pressure for human-type receptor specificity. Furthermore, in the flu season, coinfection with seasonal influenza viruses could lead to reassortment of bovine and human viruses and the creation of a hybrid virus that is more adapted for human infection.

Bird/ #cowflu #H5N1 is a single mutation away from possible human to human transmission.

The more dairy workers get infected, the higher the selective pressure for this mutation to occur.

"There are so many cattle passing away from avian influenza that the rendering trucks are backed up...We are desperately overwhelmed at this point."

Cows w/H5N1 left exposed with no warning signs or biosecurity precautions.

"The footage was deemed too graphic for publication."
