H1N1 Update
As you can see from the graph below, the cases of influenza A continue to rise and most likely have not yet peaked.
The LA County Department of health and the CDC tell us that 99% of the Influenza A isolated is the novel 2009 H1N1 influenza virus. We have yet to see wide circulation of seasonal influenza, however there have been sporadic cases of influenza B.
We expect the number of cases to continue to rise in the Southern California region and most sites are reporting about a 20-25% positivity rate for specimens submitted for testing. The distribution of the virus is worldwide and vaccine is newly available.
We have seen a few positive RSV cases, consistent with previous seasons at this time of year. We would expect the number of RSV positives to start to pick up in the next month and we will be on the look out for seasonal influenza as well.
