A high proportion of Cree and other North American Indian children have a chronic cough and many have bronchial wall thickening on radiographs, reminiscent of white children with asthma, mild cystic fibrosis, or immune deficiency. When compared to postmortem studies, radiographs underestimate the degree of bronchial wall thickening present. As compared to white children, Indian children in the first two years of life are more susceptible to recurrent bronchitis and pneumonia, are much more likely to develop pneumonia with rubeola and pertussis, and are more likely to develop chronic lung disease after adenovirus infections. Staphylococcal complications with pneumatocele formation are more common. A greater number acquire pneumonia while in hospital with other medical or surgical problems. Indian children with pneumonia recover more slowly, and some continue to deteriorate even after admission to hospital.
很大比例的克里族及其他北美印第安儿童患有慢性咳嗽，许多儿童的X光片显示支气管壁增厚，这让人联想到患有哮喘、轻度囊性纤维化或免疫缺陷的白人儿童。与尸检研究相比，X光片低估了实际存在的支气管壁增厚程度。与白人儿童相比，印第安儿童在出生后的头两年更容易患复发性支气管炎和肺炎，患麻疹和百日咳后更易发展成肺炎，腺病毒感染后更易患上慢性肺病。葡萄球菌并发症伴肺气囊形成更为常见。更多儿童在因其他内科或外科问题住院期间患上肺炎。患肺炎的印第安儿童康复较慢，有些儿童甚至在入院后病情仍持续恶化。
