INTRODUCTION: COVID-19 causes significant morbidity in the USA, particularly among American Indian/Alaska Native (AI/AN) persons. Estimates of COVID-19 burden among AI/AN communities are needed to identify health outcome disparities and inform prevention strategies, but under-ascertainment of AI/AN status in national data may result in underestimation of COVID-19 disease burden.
METHODS: Surveillance for acute respiratory illness was conducted among AI/AN persons at eight healthcare facilities in Arizona and Alaska to identify COVID-19-associated hospitalizations and outpatient visits. Weekly and annual incidence rates of COVID-19-associated hospitalizations per 100,000 persons were calculated overall and by site and age. Risk factors for COVID-19-associated hospitalizations (versus outpatient visits) were assessed.
RESULTS: From January 2021 to December 2022, 1159 COVID-19-associated hospitalizations were identified. Incidence rates were 439.8 per 100,000 in 2021 and 332.6 per 100,000 in 2022 and highest among adults ≥ 65 years at all sites. Compared to national estimates from 2021 to 2022, incidence rates by time and age were similar among older adults, whereas incidence rates among AI/AN children were over twice as high. Among adults, older age, chronic lung disease, chronic kidney disease, and diabetes increased the risk of hospitalization; frequent mask use outside the home and COVID-19 vaccination were protective, particularly if vaccinated within the past year. Among children, younger age and heart conditions increased the risk of hospitalization.
CONCLUSIONS: The findings demonstrate a substantial burden of COVID-19 in AI/AN persons and provide critically needed data regarding the risks for severe outcomes. AI/AN children experience a disproportionate burden of COVID-19 disease.
