They did quit testing most individuals though and assumed all cases were H1N1. It didn't out compete - it was just the first wave. The second wave of Flu is just building.
There is still testing being done, but it isn't being done systematically as part of an attempt to track an emerging virus. It's just not practical to test everyone with an influenza-like illness. Testing is still being ordered by hospital physicians who need to determine what is making their patient sick, and those results are still being reported to the CDC. Ever since the virus became so widespread, though, the sort of comprehensive surveillance you saw during the spring became impossible.
The overwhelming majority of lab-confirmed cases this flu season have always been the new H1N1 strain. If you look at the most recent statistics, you'll see that the new H1N1 virus has been and remains dominant. I'm sure someone will publish a seroprevalence study soon and that will answer this question even more conclusively. We'll know how many people have antibodies to the virus.
H1N1 had peaked here before the primary flu season even began.
Normal flu epidemics differ by region. An epidemic in any given region peaks in a few weeks and subsides over the following a few weeks, but different regions experience epidemics at different times. This virus behaved quite differently - it rapidly spread to every continent and is taking a much longer time to peak.
If you go back to the first part of this year, H1N1 was NOT the primary flu.
The first part of 2009? That's the tail end of the previous flu season. The new H1N1 strain didn't emerge until spring, so that makes sense. Once the new H1N1 virus emerged, it most certainly did outcompete the other viruses - first in the southern hemisphere, and then in the northern.
I think way too much was made of it by the media.
The story deserved the attention it got, but it was covered extremely irresponsibly by some. You know the media can't resist gloom and doom, though. The situation demanded caution, vigilance, and the rapid distribution of a vaccine. We got most of that, along with a generous helping of media-driven hysteria. We didn't dodge any bullets... we got hit but mother nature was playing paintball this time around.
