I haven’t seen much mention of this: After decreasing for 7 weeks, hospital visits for influenza-like illness in the US held steady for a week and have now started to increase again. The CDC chart:

CDC influenza incidence, week 51

On the other hand, Google flu trends only shows a slight increase, in line with last year, and lab-confirmed flu cases decreased slightly in this period.  Nevertheless, it will be no surprise if influenza has two peaks this season (though I expected a longer respite between peaks).  I’m guessing we’re going to see an increase in flu again over the next few weeks.

Edit: OK, well, maybe I’m jumping the gun. The rise looks like it may just be a blip, dropping down again in the subsequent week:
