From June 20 (MMWR week 25) – July 11 (MMWR week 28), overall weekly hospitalization rates increased for three consecutive weeks. Data for the weeks ending July 18 and July 25 (MMWR weeks 29 and 30) currently show a decline; however, those data are likely to change as more data for admissions occurring during those weeks are received.

Among the 42,403 laboratory-confirmed COVID-19-associated hospitalized cases, 39,983 (94.3%) had information on race and ethnicity, while collection of race and ethnicity was still pending for 2,420 (5.7%) cases. When examining overall age-adjusted rates by race/ethnicity, non-Hispanic American Indian or Alaska Native persons had an age-adjusted hospitalization rate approximately 5.3 times that of non-Hispanic White persons. Rates among non-Hispanic Black persons and Hispanic or Latino persons were both approximately 4.7 times the rate among non-Hispanic White persons.
When examining age-stratified crude hospitalization rates by race and ethnicity, compared with non-Hispanic white persons in the same age group, crude hospitalization rates were 7.8 times higher among Hispanic or Latino persons aged 0-17 years; 9.8 times higher among non-Hispanic American Indian or Alaska Native persons aged 18-49 years; 7.2 times higher among non-Hispanic American Indian or Alaska Native persons aged 50-64 years; and 3.8 times higher among non-Hispanic Black persons aged ≥ 65 years.

1 COVID-19-associated hospitalization rates by race/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.
2 For each age category, rate ratios are the ratios between crude hospitalization rates within each racial/ethnic group and the crude hospitalization rate among non-Hispanic white persons in the same age category.
3 Overall rates are adjusted to account for differences in age distributions within race/ethnicity strata in the COVID-NET catchment area; the age strata used for the adjustment include 0-17, 18-49, 50-64, and 65+ years.
Non-Hispanic Black persons and non-Hispanic White persons represented the highest proportions of hospitalized cases reported to COVID-NET, followed by Hispanic or Latino, non-Hispanic Asian or Pacific Islander and non-Hispanic American Indian or Alaska Native persons. However, some racial and ethnic groups are disproportionately represented among hospitalized cases as compared with the overall population of the catchment area. Prevalence ratios showed a similar pattern to that of the age-adjusted hospitalization rates: non-Hispanic American Indian or Alaska Native persons have the highest prevalence ratio, followed by non-Hispanic Black and Hispanic or Latino persons.

1 Persons of multiple races (0.2%) or unknown race and ethnicity (5.9%) are not represented in the table but are included as part of the denominator.
2 Prevalence ratio is calculated as the ratio of the proportion of hospitalized COVID-NET cases over the proportion of population in COVID-NET catchment area.
Among 10,687 hospitalized adults with information on underlying medical conditions, 90.8% had at least one reported underlying medical condition. The most commonly reported were hypertension, obesity, chronic metabolic disease and cardiovascular disease. Among 222 hospitalized children with information on underlying conditions, 52.3% had at least one reported underlying medical condition. The most commonly reported were obesity, neurologic conditions and asthma.
