According to Google's statistics:
2012-2013 eclipses any of the previous six seasons, and it's still very early. Of course, it could be a year the viral hit peaks high but early, a la 2009-2010, or it could have a more traditional curve like 2007-2008. If it's the latter, a lot of people are going to get sick.

Until we know more, we should be thankful for one thing: though nasty enough, the number of fatalities is not horrific (yet). And unlike the flu of 2009, this one is not unusually severe in the pregnant or the obese. It’s just contagious—mighty, mighty contagious. So contagious that watching it play out makes you begin to understand the concept of a magic spell, so quickly does it seem to spread.
I've been in bed for a couple of days now with bronchitis triggered by what seemed to be this, or something like it. Brutal. Hang in there if you're enduring this.
