There is a significant association between lower respiratory tract infections and the occurrence of adult-onset asthma, although its mechanism is unclear. Background: The role of airway bacterial infection in the asthma However, the effect of bacterial infections on asthma exacerbation has These symptoms may be caused exercise or exposure to odors, allergens, or respiratory tract infections.
