Yeah, so the big fear is obviously this virus evolves and gets much better at infecting humans. And the more chances it has to spill over into a person, the more chances it has to mutate. And scientists think, you know, that might have happened actually in this teenager in Canada who seems to have caught it maybe from a bird, that the virus actually evolved while inside of them.

And then that's what ended up leading to such a serious illness. Thankfully, there is no evidence this person spread it to anyone else. And we did get a reminder of how things could go south here. There was a recent study from Scripps Research Institute, and it looked at the protein on the virus that I had mentioned before to see how it would need to change to better infect humans.

And to their surprise, they discovered it would take just one mutation. They were expecting it would take three.

That's right. So this doesn't mean there's going to be a pandemic tomorrow. There would have to be other changes in the virus to help it spread easily between humans. Scientists have an idea of what some of those can be. Others are kind of unknown at this point.

A big thing we're watching, especially as flu season is underway, is that a person who is infected with seasonal influenza, you know, which humans catch all the time, could also be co-infected with bird flu. And that could lead to a process of genetic mixing known as reassortment. And this has been a key process in previous influenza pandemics. It's possible this could happen in a person.

It's possible it could happen in a pig. These are some of the things we're watching as bird flu stretches into the next year.
