National, Regional, and State Level Outpatient Illness and Viral Surveillance
This application showcases two of CDC’s influenza surveillance systems, the WHO/NREVSS Collaborating Labs and the US Outpatient Influenza-like Illness Surveillance Network (ILINet). Users are able to view both influenza laboratory data and medically attended visits for influenza-like illness (ILI) side by side for the influenza season and geography (national, regional, or select states) of interest.
Age Group Distribution of Influenza Positive Tests Reported by Public Health Laboratories
A second application also shows the age group distribution of influenza positive tests that are reported by public health laboratories by influenza virus type and subtype/lineage. This application allows users to view laboratory data from multiple seasons and different age groups.
FluSurv-NET Hospitalization Rates
This application shows cumulative and weekly hospitalization rates from FluSurv-NET, a population-based surveillance network for laboratory-confirmed influenza-associated hospitalizations. This application allows users to view rates across multiple seasons and different age groups.
FluSurv-NET Hospitalizations with Characteristics
A second application also shows data from FluSurvNET but focuses on the characteristics (such as the virus type, demographic, and clinical information) of these hospitalizations.
National Healthcare Safety Network (NHSN) Hospitalizations Surveillance
This application shows the number and rate of laboratory-confirmed influenza- associated hospital admissions and the number of influenza-associated ICU hospitalizations from the National Healthcare Safety Network’s (NHSN) hospitalization surveillance system. This application allows users to view data at the national and HHS region level across multiple seasons.
ILI Activity Indicator Map
This application shows ILI activity by state using data collected through ILINet. This interactive tool allows users to view state-specific activity levels for multiple seasons and to have a visual representation of relative activity from state to state. For more in depth state level information, users can access state influenza surveillance websites by clicking on the state.
Influenza Mortality Surveillance from the National Center for Health Statistics Mortality Surveillance System
This application shows national, regional, and state-level influenza mortality data from the National Center for Health Statistics (NCHS) Mortality Surveillance System.
Influenza Associated Pediatric Mortality
This application shows information collected through the Influenza-Associated Pediatric Mortality Surveillance System and allows users to view case characteristics including basic demographics, underlying conditions and time and place of death.
Human Infections with Novel Influenza A Viruses
This applications shows information collected on human infections with novel influenza A viruses and allows users to view case counts by geographic location, virus subtype, influenza season, and calendar year.
