It's still all H1N1 Influenza

As you can see from the graph we are still having quite a bit of influenza A circulating and from the CDC and LA County information we know that this is almost exclusively H1N1. We have not yet seen seasonal influenza circulating and have had only a few influenza B. Parainfluenza also is circulating, although in much smaller numbers than influenza A. The overall influenza trend in our reporting sites is paralleling the experience nationwide with a downturn in the number of positive tests and hospital admissions for influenza A and ILI.

There are very few positive RSV tests and we would expect this to increase as we head into December. Stay tuned to this site and we will keep you updated on all respiratory viruses detected in the LA County area.
