The COVID-19-Associated Hospitalization Surveillance Network (COVID-NET) conducts population-based surveillance for laboratory-confirmed COVID-19-associated hospitalizations in select counties participating in the Emerging Infections Program (EIP) and the Influenza Hospitalization Surveillance Project (IHSP).
A total of 23,811 laboratory-confirmed COVID-19-associated hospitalizations were reported by sites between March 1, 2020, and May 23, 2020. The overall cumulative hospitalization rate was 73.3 per 100,000 population. Among the 0-4 years, 5-17 years, 18-49 years, 50-64 years, and ≥ 65 years age groups, the highest rate of hospitalization is among adults aged 65 years (229.7 per 100,000), followed by adults aged 50-64 years (113.4 per 100,000) and adults aged 18-49 years (41.0 per 100,000).
Within the 18-49 years and ≥ 65 years age groups, the hospitalization rates increased with increasing age.

Among the 23,811 laboratory-confirmed COVID-19-associated hospitalized cases, 19,775 (83%) had information available on race and ethnicity while collection of race and ethnicity data was still pending for 4,036 (17%) cases. Of the 19,775 cases with race and ethnicity data, 35.6% were non-Hispanic White, 34.1% were non-Hispanic Black, 17.9% were Hispanic/Latino, 4.5% were non-Hispanic Asian/Pacific Islander, 1.4% were non-Hispanic American Indian/Alaska Native, 0.2% were multiple race, and 6.3% had unknown race. In comparison, the COVID-NET catchment area population includes 58.8% non-Hispanic White, 17.7% non-Hispanic Black, 14.0% Hispanic/Latino, 8.8% non-Hispanic Asian/Pacific Islander, and 0.7% non-Hispanic American Indian/Alaska Native residents. Additional data on race and ethnicity by age are available.
COVID-19-associated hospitalization rates by race and ethnicity are calculated using hospitalized COVID-NET cases with known race and ethnicity for the numerator and NCHS bridged-race population estimates for the denominator. Rates are adjusted to account for differences in age distributions within race and ethnicity strata in the COVID-NET catchment area; the age strata used for the adjustment include 0-17, 18-49, 50-64, 75-84, and ≥85 years. Age-adjusted hospitalization rates are highest in non-Hispanic American Indian/Alaska Native and non-Hispanic Black populations, followed by Hispanic/Latino. Non-Hispanic Black and non-Hispanic American Indian/Alaska Native populations have a rate approximately 4.5 times that of non-Hispanic Whites, while Hispanic/Latinos have a rate approximately 3.5 times that of non-Hispanic Whites.
Among 5,187 hospitalized adults with information on underlying medical conditions, 91.7% had at least one reported underlying medical condition, the most commonly reported were hypertension, obesity, chronic metabolic disease, and cardiovascular disease.
