RSV Activity

Respiratory Viral Activity In Southern California

Still not much influenza in Southern California

We continue to see high levels of RSV in Southern California. This past week we were clocking in at 30% positive of specimens submitted to the local reporting laboratories. Our influenza rates are extremely low. This time last year we were well into influenza season with significant rates throughout the area. Stay tuned to this site for the most up to date numbers on RSV and influenza.
Also please refer to the CDC website: cdc.gov/flu for the most recent updates on resistant influenza. So far this season (with very few isolates available for testing) the majority of H1N1 isolates are RESISTANT to Oseltamivir but retain susceptibility to both Zanamivir and the adamantadines (Rimantidine and Amantidine).
Recommendations for both prophylaxis and treatment of influenza are updated based on the continued surveillance by the CDC and antiviral testing.

Respiratory Viral Activity In Southern California

RSV is the big player. We are over 1/4 of specimens testing positive. Influenza however, remains at very low levels (3.4% from the most recent CDC reporting). We have had a few sporadic positives from the Southern California reporting hospitals, but haven't yet hit the big time! Stay tuned for the latest counts and this is where you will see Infuenza reported first!
