Slow Influenza Season

As you can see from the latest updated graph we are having almost exclusively an "RSV respiratory viral season". Our RSV numbers continue to be high and our sites are reporting up to 45 % positivity.
Elsewhere in the country influenza is in full swing (see US map), comparable to previous years. Of the H1 strains isolated and typed 90% were similar to A/New Caledonia/20/99-like, which is the influenza A (H1) component of the 2006-07 influenza vaccine. Similarly, the H3 isolated viruses were characterized as A/Wisconsin/67/2005-like, which is the influenza A (H3) component of the 2006-07 influenza vaccine. As far as Influenza B viruses, 52% were similar to B/Ohio/01/2005, the B component of the 2006-07 influenza vaccine.
Bottom line, there is still time to get that flu shot, because it is most likely coming.
