- Respiratory illness in factory and office workers: A study of minor respiratory illnesses in relation to changes in ventilatory capacity, sputum characteristics, and atmospheric pollutionBritish Journal of Diseases of the ChestVol. 59Issue 2
- PreviewDuring the winter months of 1962–63 observations were made of respiratory symptoms in a group of 85 men working in two factories and a large office block, the majority of whom had some evidence of chronic bronchitis. The respiratory illnesses were classified on a symptomatic basis into coryza, chest colds, mucopurulent bronchitis, wheezy attacks, and “'flu” or acute respiratory disease. Chest colds and mucopurulent bronchitis were more frequently observed and were of longer duration in the men who had persistent expectoration of sputum between their illnesses than in those without sputum between their illnesses.
