From the New York Times I'm Sabrina Tavernisie and this is the daily.

The outbreak of bird flu that is tearing through the nation's poultry farms is the worst in U.S. history.

But scientists say it's now starting to spread into places and species it's never been before.

Today, my colleague Emily Anthus explains. It's Monday, April 22nd.

Emily, welcome back to the show.

Thanks for having me, happy to be here.

So Emily, we've been talking here on the daily about prices of things and how they've gotten so high

mostly in the context of inflation episodes and one of the items that keeps coming up is eggs

Egg prices were through the roof last year and we learned it was related to this. Avian flu has been surging in the United States.

You've been covering this.

Tell us what's happening.

Yeah, so I have been covering this virus

for the last few years and the bird flu is absolutely tearing through

poultry flocks and that is affecting egg prices. That's a concern for everyone

for me and for my family.

But when it comes to scientists,

egg prices are pretty low on their list of concerns

because they see this bird flu virus

behaving differently than previous versions have.

And they're getting nervous in particular about the fact that this virus is reaching places and

species where it's never been before.

Okay, so bird flu, though, isn't new. I mean, I remember hearing about cases in Asia and the 90s.
