Seriously? Because it’s too early to tell what the final stats will be given we haven’t passed the time of year when most people have died of flu each year. 8,000 died during what is usually the off-season for the flu, but we won’t know until May if this flu is unusual because it causes the bulk of deaths at a different time of year, or if those 8,000 deaths will be in addition to the typical 40,000 deaths we see with other flus. Saying definitively that “only 8,000” died of this flu right now is like deciding the outcome of a ballgame during the 5th inning.

He would answer your question, but as well as not reading newspapers, he also frequently fails to return to threads that he starts.

Well, **Marxxx** isn’t entirely wrong, because in terms of [pediatric deaths](http://www.cdc.gov/flu/weekly/weeklyarchives2009-2010/IPD02.htm) we already know that this ball game was a blow out. The fact that ultimately this flu season may turn out to be relatively mild in terms of overall deaths really is irrelevant when discussing a virus that was clearly a killer. Maybe with 20/20 hindsight, it wasn’t quite as bad as it might have been, but that’s some pretty good hindsight. We have no idea what this flu season would have been like had people not gotten vaccinated or slightly changed their routines.

The only real danger is that people will come to believe that this was all hysterics, so that when the next warning comes out, they feel justified in ignoring it.
