29 dead is a lot, right?

YES!  It's early in the flu season.  H1N1 is deadly.

How long does flu season go on?!

In the Northern hemisphere, winter is the time for flu, but the exact timing and duration of flu seasons vary. While flu outbreaks can happen as early as October, most of the time flu activity peaks in January or later.* The figure below shows peak flu activity for the United States by month for the 1982-83 through 2012-2013 flu seasons. The “peak month of flu activity” is the month with the highest percentage of respiratory specimens testing positive for influenza virus infection. During this 31-year period, flu activity most often peaked in February (14 seasons, or 45% of the time), followed by December, January and March (which each peaked during 5 seasons, or 16% of the time).

*During 2008-2009, flu activity peaked twice because of the 2009 H1N1 pandemic. Activity in the United States peaked once in in February due to seasonal influenza activity and then again in the Spring (June), with the first wave of 2009 H1N1 viruses A second, larger peak of 2009 H1N1 activity occurred in October, the peak of the 2009-2010 season.

Ok, cool, so we're really not out of it till April.
