Purpose
RESP-NET interactive dashboard
RESP-NET is made up of three networks that monitor laboratory-confirmed hospitalizations associated with influenza (FluSurv-NET), COVID-19 (COVID-NET), and RSV (RSV-NET).
The rates presented on the RESP-NET interactive dashboard can be used to follow trends and comparisons of influenza, COVID-19, and RSV-associated hospitalizations in different demographic groups and over time. CDC uses a Nowcast modeling tool to estimate weekly respiratory virus-associated hospitalization rates for the most recent 3 weeks, before surveillance data are fully reported and while hospitalization reports are still coming in.
This dashboard is updated weekly. Data are preliminary and subject to change as more data become available. Rates for recent hospital admissions are subject to reporting delays that might increase around holidays or during periods of increased hospital utilization. As new data are received each week, previous rates are updated accordingly.
Why RESP-NET data are important
COVID-19, RSV, and influenza-associated hospitalization rates are used to understand trends in virus circulation, estimate disease burden, and respond to outbreaks. Demographic and detailed clinical information, including underlying medical conditions, allow CDC to better understand hospitalization trends and determine who is most at risk for severe illness. These data guide public health planning and decision making.
RESP-NET does not collect data on all hospitalizations associated with respiratory viruses, but it can describe hospitalizations associated with influenza, SARS-CoV-2 (the virus that causes COVID-19), and RSV. It is estimated that these respiratory viruses accounted for more than one million hospitalizations in the United States from October 2024 through September 2025. Surveillance is conducted through a network of acute care hospitals in select counties or county equivalents in:
- 14 states and up to 194 counties for influenza, COVID-19, and RSV surveillance.
These surveillance platforms cover more than 40.9 million people or an estimated 12% of the U.S. population.
The surveillance platforms for these viruses are FluSurv-NET, COVID-NET, and RSV-NET.
Rates presented on the RESP-NET interactive dashboard can be used to follow trends and compare COVID-19, influenza, and RSV-associated hospitalization rates in different demographic groups. This includes data by age group, sex, and race and ethnicity, and across seasons and states.
Surveillance in RESP-NET relies on clinical testing ordered by a healthcare provider. Hospitalization rates are unadjusted and do not account for undertesting, differing provider or facility testing practices, and diagnostic test sensitivity. The true burden of hospitalizations associated with influenza, COVID-19, and RSV in the United States may be greater than what is shown by these numbers.
