The CDC only has weekly figures for the last three years online. For the same period in the last three years, there have been no children dying from flu. For the winter period over the last few years, we have seen slightly more dying from flu than we've just seen over the summer.

Check jaunty-backports first, if not there's probably a PPA. Of course wtih a PPA it's essentially unverified and not security patch supported. I really wish there was more of a "auto-backports" service for the most popular distros - basically like doing a nightly build of upstream except it's a package. And of course untested and unsupported in every way.
