From CDC site:
The fact that novel H1N1 activity can now be monitored through seasonal surveillance systems is an indication that there are higher levels of influenza-like illness in the United States than is normal for this time of year. About half of all influenza viruses being detected are novel H1N1 viruses.

There were the math models for pandemic spread of flu online when this virus first became public. It showed a slow, but steadily increasing number of infection which got seriously heavy on day 50 and peaked at day 85. By day 120 it's headed back to - but not quite to yet - normal. It is a slow-moving long term event.
At present we are about at day 17 in the whole cycle...
