Disparities in Outcomes During Lower Respiratory Tract Infection in American Indian Children: A 9-Year Retrospective Analysis in a Rural Population in South Dakota.

Background: American Indian (AI) children are at increased risk for severe disease during lower respiratory tract infection (LRTI). The reasons for this increased severity are poorly understood. The objective of this study was to define the clinical presentations of LRTI and highlight the differences between AI and non-AI previously healthy patients under the age of 24 months.
