CDC's influenza surveillance system is comprised of the following eight components:
* Laboratory Surveillance: Influenza laboratory surveillance is comprised of 2 networks of laboratories (150 laboratories) that report influenza data: U.S. World Health Organization Collaborating Laboratories and National Respiratory and Enteric Virus Surveillance System Collaborating Laboratories.
* Mortality Surveillance: Pneumonia and influenza related mortality data are reported through the 122 Cities Mortality Reporting System. Each week, the vital statistics offices report the total number of death certificates received and the number of those for which pneumonia orinfluenza was listed as the underlying or as a contributing cause of death by age group.
*Outpatient influenza-like illness (ILI) surveillance: Outpatient ILI data are collected through the U.S. Influenza Sentinel Provider Surveillance Network, a collaborative effort between CDC, state and local health departments, and health care providers. During the 2007-08 season,approximately 2,500 providers in 50 states were enrolled and over 1,800 reported at least once the total number of patients seen and the number of those patients with ILI by age group on a weekly basis.
* State and Territorial Epidemiologists Report: State health departments report the estimated level of influenza activity in their state each week as sporatic, local, regional or widespread.
* Influenza-associated pediatric mortality: Influenza-associated pediatric mortality is a nationally notifiable condition. Laboratory-confirmed influenza-associated deaths in children less than 18 years old are reported through the Nationally Notifiable Disease Surveillance System.
* Human Infections with Novel Influenza A Viruses: Human infections with novel influenza A viruses is a newly added nationally notifiable condition reportable through the Nationally Notifiable Disease Surveillance System.
* Emerging Infections Program (EIP): The EIP Influenza Project conducts surveillance for laboratory-confirmed influenza related hospitalizations in persons less than 18 years of age in 60 counties covering 12 metropolitan areas of 10 states (San Francisco CA, Denver CO, New Haven CT, Atlanta GA, Baltimore MD, Minneapolis/St. Paul MN, Albuquerque NM, Las Cruces, NM, Albany NY, Rochester NY, Portland OR, and Nashville TN).
* New Vaccine Surveillance Network (NVSN): The NVSN provides population-based estimates of laboratory-confirmed influenza hospitalization rates for children less than 5 years old residing in 3 counties: Hamilton County OH, Davidson County TN, and Monroe County NY. Children admitted to NVSN hospitals with fever or respiratory symptoms are prospectively enrolled and respiratory samples are collected and tested by viral culture and RT-PCR. NVSN estimated rates
are reported every two weeks during the influenza season.
Data Feedback: There is a dedicated website (http://www2.ncid.cdc.gov/flu/) for the US Influenza Sentinel Provider program. Sentinel providers and state influenza surveillance coordinators are assigned an ID and a password for this site that allow different levels of data entry and viewing.
When a provider logs on, he/she can enter their data and/or view their own data.
When a state coordinator logs on, he/she can enter data for any of their providers, delete duplicate records, and view a line list of weekly influenza data reported to CDC by sentinel providers and laboratories in their state.
... national sentinel provider and laboratory data are also available in chart and table format. Data entered on the Internet will be immediately available and reflected in all charts and tables on the website. Data transmitted via fax will be updated once a day Monday through Friday.
