Groups Most Impacted—Hospitalizations

Provides an update on how COVID-19, influenza, and RSV hospitalizations are affecting different groups.

Groups Most Impacted Update:
  • As a percent of all emergency department visits, children under 18 have the highest proportion of diagnosed influenza visits. Influenza visits decreased or remained stable in all age groups. COVID-19-related emergency department visits are highest among infants under 12 months and adults 65+; visits due to diagnosed RSV are highest among infants under 12 months.
  • Rates of influenza-related hospitalizations are elevated in all age groups; adults 65+ have the highest rate compared to other age groups. Non-Hispanic American Indian/Alaska Native and Non-Hispanic Black persons have the highest age-adjusted influenza hospitalization rate compared with other racial and ethnic groups. Rates of COVID-19 and RSV hospitalizations are decreasing but remain elevated among adults 65+ and infants under 12 months.
  • Nationally, the percent of total deaths due to COVID-19, influenza, or RSV were highest (4.2%) among adults 65+.

  • SOURCE: Respiratory Virus Hospitalization Surveillance Network (RESP-NET).
  • Combined is the sum of COVID-19, influenza, and respiratory syncytial virus (RSV) hospitalization rates.
  • Additional information, including the surveillance catchment area, is available at https://www.cdc.gov/surveillance/resp-net/dashboard.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 lag.
  • Incidence rates of COVID-19- and respiratory syncytial virus (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 influenza-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.
  • COVID-19 and respiratory syncytial virus (RSV) surveillance are currently conducted year-round. For influenza, the surveillance period begins October 1 and ends April 30 of each year.
  • FluSurv-NET surveillance for the 2023-24 season began on October 1, 2023.
  • Rates are likely to be underestimated as some COVID-19-, influenza-, and respiratory syncytial virus (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 ages <6 months and 6 months to <12 months, 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.
