The percentage of respiratory specimens testing positive for influenza in clinical laboratories increased.

  • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 3.2%, which is above the national baseline of 2.1%. All 10 regions reported ILI at or above region-specific baseline levels. Puerto Rico and six states experienced high ILI activity; New York City and six states experienced moderate ILI activity; 13 states experienced low ILI activity; 24 states experienced minimal ILI activity; and the District of Columbia and one state had insufficient data.
