title: Adenovirus type 21 bronchopneumonia in infants and young children.
abstract: An epidemic of bronchopneumonia in infants and young children, with adenovirus type 21 infection, was observed in Auckland, New Zealand, in 1977. Eighteen children, four to 44 months of age, with clinical and radiologic evidence of bronchopneumonia are described. Several of the children were seriously ill but there were no deaths. When reviewed six to 12 months after diagnosis, six children had clinical signs and 13 had radiologic signs of residual pulmonary disease. There were no detectable pulmonary sequelae in two children. Three children were lost to follow-up and could not be evaluated. Adenovirus type 21 bronchopneumonia is a serious illness and an important cause of chronic bronchopneumopathy in infants and young children.
