Situation Update: Summary of Weekly FluView
Key Flu Indicators
Today, October 15, 2010, CDC issued its first FluView for the 2010-2011 season. It contains data for the week of October 3-9, 2010. During the week of October 3a??9, 2010, nationally all key flu indicators are low. Below is a summary of the most recent key indicators:
- Visits to doctors for influenza-like illness (ILI) are low nationally, with all 10 U.S. regions reporting ILI below region-specific baseline levels.
- The proportion of deaths attributed to pneumonia and influenza (P&I) based on the 122 Cities Report is low at this time.
- No influenza-associated pediatric deaths were reported this week, but two pediatric deaths have occurred since May 23, 2010 (one in Louisiana and one in Texas). One death was associated with an influenza A virus for which the subtype was undetermined, and one death was due to an untyped influenza virus. These deaths occurred during June 6-12, 2010.
- No states reported widespread or regional influenza activity. Sporadic influenza activity was reported by 19 states and the District of Columbia, Guam and Puerto Rico. Thirty-one states reported no influenza activity.
- Influenza viruses identified so far include 2009 H1N1 viruses, influenza A (H3N2) viruses and influenza B viruses. These viruses remain similar to the viruses chosen for the 2010-2011 flu vaccine, and remain susceptible to the antiviral drugs oseltamivir and zanamivir.
