It is because Covid is considered endemic. Meaning it is here, infecting humans and it is here to stay. We also have treatments, they may not work for everyone, but that's also normal.

The bird flu is not endemic. The name kind of says it, its still mostly in birds. The reason why people focus on a single case in humans is that such an event could trigger the broad adaptation of the virus to humans (zoonosis).

Right now the virus has low potential to get transmitted, because it has not yet adapted to humans. If this happens, it could very well trigger the next pandemic.

And if you were unhappy about how fast the Coronavirus could mutate over the course of pandemic... well then get ready for worse since Influenza viruses whole deal is about mutating and recombining their transcripts.

So yes, there is a reason people focus so much on this one case.
