Viral respiratory season around the corner!

We are starting to see some circulating respiratory viruses of interest! Parainfluenza remains the most commonly isolated virus (second of course to Rhinovirus!). Adenovirus is a close second and so far RSV and Influenza far behind. There have been a few sporadic RSV positives reported in Southern California and the occasional Influenza A, but nothing too significant. Perfect time to start immunizing for influenza if you haven't already! Stay tuned for graphs, up to date reporting and percent positives (endemic monitoring) for RSV.

Respiratory Viral Activity

The amount of RSV circulating is holding just above endemic levels-at 10-12% but the amount of influenza has been declining over the past few weeks. Most of the Influenza is A with only an occasional B isolated. We continue to see Adenovirus, Human metapneumovirus and an occasional Parainfluenza. We will keep monitoring and let you know when levels drop below our 10% cutoff for endemic circulation.

INFLUENZA!

Influenza is on the RISE and RSV remains steady with only a slight decrease over the past week. We are still seeing >10% of specimens positive (endemic levels), much later a season than last year. As for influenza, a very late and relatively mild season but we are seeing increasing numbers of Influenza A (mostly 2009 H1N1) and some Influenza B. Human metapneumovirus, so strong over the past few weeks is decreasing in numbers. Stay tuned.
