The aim of this study was to investigate the relation of viral respiratory infection with bronchial hyperreactivity and bronchial obstruction. A viral infection using a live attenuated influenza virus was induced successfully in 10 of 30 patients with chronic obstructive pulmonary disease (COPD) and in 3 subjects without COPD (non-COPD). No significant change in bronchial reactivity and lung function could be found in comparison with the baseline values.
