Q. How did the chicken cross the road?
A. It flu.

“The genetic data is clear that once this strain of bird flu—H5N1 clade 2.3.4.4 genotype B3.13 —hopped into cattle, it could readily spread to other mammals. The genetic data links viruses from cattle moving many times into other animals: There were five cattle-to-poultry jumps, one cattle-to-raccoon transmission, two events where the virus moved from cattle to domestic cats, and three times when the virus from cattle spilled back into wild birds.”

“Concerning” spread of bird flu from cows to cats suspected in Texas

Mammal-to-mammal transmission raises new concerns about the virus's ability to spread.

It is concerning that the H5N1 has spread to multiple herds of cattle around several states in a few weeks.

The really worrying part of this story is how it spread from the cattle to the cats in about a week killing 50% of the poor things.

Several dairy workers also appear to have caught it too. At this rate of spread and across mammals it could make the COVID outbreak look tame.

Time to start stockpiling again?
