People Most Impacted by Respiratory Viruses

Below, you will find the weekly percent of all ED visits attributed to COVID-19, flu, and RSV broken down by race and ethnicity. This data comes from people going to emergency departments but NOT being admitted for further care. It is important to look at these numbers to identify and address differences in health outcomes or in access and resources available to different communities.

Please note, prior to the 2025–26 season, monitoring of seasonal influenza ended on April 30 of each year. Starting with the 2025–26 season, tracking data for flu-associated hospital admissions from RESP-NET are year-round and continue until September 30, 2026.

Below, you will find weekly percent of deaths from COVID-19, flu, and RSV, categorized by race and ethnicity.

Below, you will find the weekly percent of all hospitalization for COVID-19, flu, and RSV, based on sex. Looking at data by sex (male/female) helps us identify differences in healthcare for men and women. This information can guide improvements in care, shape policy, improve research, and address social issues.

Below, you will find the weekly hospitalization numbers for COVID-19, flu, and RSV per 100,000 people, based on sex (male/female). This number reflects people admitted to the hospital for further care and treatment.

• SOURCE: National Syndromic Surveillance Program: https://www.cdc.gov/nssp/index.html
• Combined is the sum of COVID-19, flu, and RSV emergency department visits.
• For more detailed information on these data please see the Companion Guide: NSSP ED Data on Respiratory Illness | National Syndromic Surveillance Program (NSSP) | CDC

• SOURCE: Respiratory Virus Hospitalization Surveillance Network (RESP-NET).
• Influenza data for the week ending May 3, 2025, includes data from April 27, 2025, through April 30, 2025.
• Additional information, including the surveillance catchment area, is available at https://www.cdc.gov/resp-net/dashboard/index.html.
• Data are preliminary and subject to change as more data become available. In particular, case counts and rates for recent hospital admissions are subject to delay.
• Incidence rates of COVID-19 and RSV-associated hospitalizations (per 100,000) are calculated using the National Center for Health statistics (NCHS) vintage 2020 bridged-race postcensal population estimates for the counties included in the surveillance area, while incidence rates of flu-associated hospitalizations (per 100,000) are calculated using U.S. Census vintage 2022 unbridged-race postcensal population estimates for the counties or county-equivalents included the surveillance area.
• We conduct COVID-19 and RSV surveillance year-round. Prior to the 2025–26 season, the flu surveillance period began on October 1 and ended April 30 of each year. Starting with the 2025-26 season, flu surveillance became year-round.
• FluSurv-NET surveillance for the 2023–24 season began on October 1, 2023.
• Rates are likely to be underestimated as some COVID-19, flu, and RSV-associated hospitalizations might be missed because of undertesting, differing provider or facility testing practices, and diagnostic test sensitivity. Rates presented do not adjust for testing practices which may differ by pathogen, age, race and ethnicity, and other demographic criteria.
• The NCHS bridged-race population estimates or U.S. Census unbridged-race postcensal population estimates used as denominators for race provide data for children ages 0–1 year. To calculate rates of hospitalization among children less than 6 months and 6 months to a year or older, the population estimate for children ages 0–1 year is halved.
• Black, White, American Indian/Alaska Native, and Asian/Pacific Islander people were categorized as non-Hispanic; Hispanic people could be of any race. If Hispanic ethnicity was unknown, non-Hispanic ethnicity was assumed. Rates presented by race and ethnicity are calculated using records with known race. Those with missing or unknown race are excluded from race-specific estimates but are included in overall estimates.

• Source: Provisional Deaths from the CDC's National Center for Health Statistics (NCHS) National Vital Statistics System (NVSS). Accessed from https://wonder.cdc.gov/mcd-icd10-provisional.html
• Provisional data are non-final counts of deaths based on the flow of mortality data in NVSS. Data during recent periods are incomplete because of the lag in time between when a death occurs and when a death certificate is completed, submitted to NCHS, and processed for reporting. This delay can range from 1 week to 8 weeks or more, depending on the jurisdiction.
• Definitions: Provisional data are non-final counts of deaths based on the flow of mortality data in NVSS. Cause-specific death counts are defined as those deaths with the designated ICD-10 codes listed as an underlying or contributing cause of death on the death certificate. The ICD-10 code definitions are as follows: COVID-19 (U07.1), flu (J09-J11), RSV (J12.1, J20.5, J21.0).
• Death data are displayed by date of death. Death data reported are based on the total number of deaths received and coded as of the date of analysis and may not represent all deaths that occurred in that period.
• Percent of deaths is not presented for weeks where death counts are between 1–9 in accordance with NCHS data confidentiality standards.
• Provisional death data represent deaths among U.S. residents and occurring in the 50 states, plus the District of Columbia. Assignment to a geographic area is based on the place of residence listed on the death certificate. Data from U.S. territories are not currently included in NVSS provisional reporting.
• The percentage of all reported deaths that are attributed as COVID-19, flu, and RSV is calculated as the number of COVID-19, flu, and RSV deaths divided by the number of deaths from all causes multiplied by 100. The percentage of deaths is less affected by incomplete reporting in recent weeks because death certificate data from natural causes of death and all causes have similar timeliness.
