Respiratory Viral Activity In Southern California

As you can see from the graphs we are at the end of SEASONAL influenza and RSV seasons. We had only a few RSV positive samples last week for 1% of tested samples.

We are seeing some Parainfluenza (mostly 2 and 3) and a few human metapneumoviruses as well.

We have had a few influenza B isolated and of course we are all keeping our eyes fixed on the changing situation here and abroad with Swine Flu (H1N1).
The most up to date information can be obtained on the CDC website: CDC.gov/swineflu and I would recommend consulting this for questions concerning possible suspect cases. Currently , individuals in California with a positive exposure history who are symptomatic and test positive for influenza A are having their isolates analyzed by the county health departments for verification of swine flu. Recommendations for isolation, treatment and prophylaxis can be found on this frequently updated website.
