A dangerous type of bird flu virus discovered in the lung of a U.S. dairy cow that didn't show symptoms. Viral particles identified in processed, pasteurized milk. Genetic sequences showing distinct changes in this H5N1 strain that's been rapidly spreading throughout American cattle.
Those were just a handful of the rapid-fire developments this week as an unprecedented H5N1 outbreak among U.S. dairy cattle continued to evolve.
Scientists now warn this form of avian influenza is likely more widespread in cows, and was transmitting for longer than official reports suggest. And while American officials are ramping up testing all in an effort to keep sick cows from being moved between states others say we're already several steps behind the spread of a disease that could pose a major threat to human health.
Michael Worobey, a researcher from B.C. who's now head of the department of ecology and evolutionary biology at the University of Arizona, said these cattle infections may have been "flying under our radar for months," providing ongoing opportunities for this virus to acquire adaptations that could lead to a flu pandemic. "I think, in many ways, this is the biggest news story in the world right now."

This was way before it was known that it's spread through tissue. The CDC didn't even know what infection control precautions were needed so I ended up being in head to toe PPE*, donning and doffing every time I went to treat him. Turns out none of it was necessary.
He was a very nice man that I watched deteriorate in the most horrendous way through day to day changes that we could do nothing to stop or even marginally ameliorate. It was really scary for him especially and his family, too.
*PPE required by the CDC at the time

The mad cow crisis is a health and socio-economic crisis characterized by the collapse of beef consumption in the 1990s, as consumers became concerned about the transmission of bovine spongiform encephalopathy (BSE) to humans through the ingestion of this type of meat.

It would be a perfect ending for you know who.
