The mutation detected on the virus infecting a dairy farm worker in Texas has been recorded previously, the CDC said — and did not spark a major outbreak at that time. The change, on the PB2 ...
Yoshi Kawaoka: So in the past, there are avian influenza viruses that are in migratory waterfall [that] acquired mutations in PB2 proteins that make the virus replicate better in mammalian species.
A genetic mutation of H5N1 detected in California dairy cows raises concerns about increased mammal-to-mammal transmission and potential human infections.
the USDA reported finding that the D1.1 strain infecting cows in Nevada has a notable mutation known to help the bird-adapted virus replicate in mammals more efficiently (PB2 D701N). To date ...
