  All data are preliminary and may change as more reports are received.
  
  Background: The Centers for Disease Control and Prevention’s (CDC) Influenza Division collects, compiles, and analyzes information on influenza activity year-round in the United States and produces FluView, a weekly influenza surveillance report, and FluView Interactive. The U.S. influenza surveillance system provides information in five categories collected from nine data sources. This is the first report of the 2015-2016 influenza season, which began on October 4, 2015.
  
  The five categories and nine data components of CDC influenza surveillance are:
  
  • Viral Surveillance: U.S. World Health Organization (WHO) collaborating laboratories, the
  
  • National Respiratory and Enteric Virus Surveillance System (NREVSS), and human infection
  
  • with novel influenza A virus case reporting;
  
  • Mortality: National Center for Health Statistics (NCHS) Mortality Surveillance System, 122
  
  • Cities Mortality Reporting System and influenza-associated pediatric deaths;
  
  • Hospitalizations: Influenza Hospitalization Network (FluSurv-NET) including the Emerging
  
  • Infections Program (EIP) and three additional states;
  
  • Outpatient Illness Surveillance: U.S. Outpatient Influenza-like Illness Surveillance Network
  
  • (ILINet);
  
  • Geographic Spread of Influenza: State and territorial epidemiologists’ reports.
  
  An overview of the CDC influenza surveillance system, including methodology and detailed descriptions of each data component, is available at: http://www.cdc.gov/flu/weekly/overview.htm.
  
  Synopsis: During week 40 (October 4-10, 2015), influenza activity was low in the United States.
  
  • Viral Surveillance: The most frequently identified influenza virus type reported by public health laboratories in week 40 was influenza A viruses, with influenza A (H3) viruses predominating. The percentage of respiratory specimens testing positive for influenza in clinical laboratories is low.
  
  • Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below their system-specific epidemic threshold in both the NCHS Mortality Surveillance System and the 122 Cities Mortality Reporting System.
  
  • Influenza-associated Pediatric Deaths: No influenza-associated pediatric deaths were reported.
  
  • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 1.2%, which is below the national baseline of 2.1%. All 10 regions reported ILI below region-specific baseline levels. Georgia experienced low ILI activity; Puerto Rico, New York City and 47 states experienced minimal ILI activity; and the District of Columbia and two states had insufficient data.
  
  • Geographic Spread of Influenza: The geographic spread of influenza in Guam was reported as widespread; one state reported regional activity; one state reported local activity; Puerto Rico and 27 states reported sporadic activity; the U.S. Virgin Islands and 21 states reported no influenza activity; and the District of Columbia did not report.
