RSV in Southern California

Respiratory Viral Isolates

Respiratory Viral Activity

The last few weeks have shown a significant decline in the number of influenza A (H1N1) cases throughout Southern California.
We are also starting to see the start of an RSV season (significantly later this year than in previous years!) We are now at almost 6% of specimens testing positive for RSV but this number is sure to jump in the next few weeks. When we hit 10% we declare RSV to be circulating in an endemic fashion. We are also continuing to see some parainfluenza 1 as well as human metapneumovirus in the community. Stay tuned for more viral information and percentages.
