Exacerbations of bronchiectasis that are caused by acute bacterial infections are often heralded by the onset of increased sputum production over baseline, increased viscidity of sputum, and, occasionally, a foul odor of the sputum. Rarely, low-grade fever may occur. Patients may experience an increase in generalized constitutional symptoms, such as fatigue and malaise, as well as increased dyspnea, shortness of breath, wheezing, or pleuritic pain.

With secondary infection or poorly treated pneumonia, the discrete pathogens are often unknown. However, most patients relate a history of childhood infections that may include tuberculosis, pertussis, or Mycoplasma infection. [14]
