Currently no systematic data are available on the incidence or prevalence of bronchiectasis. A general theory is that the emergence of vaccines and antibiotics in the 20th century resulted in a decline in the rate of bronchiectasis in developed countries. [17]

The best data available suggest that the prevalence of bronchiectasis mirrors the socioeconomic conditions of the population under study, with significantly lower prevalence in areas where immunizations and antibiotics are readily available. Bronchiectasis remains a major cause of morbidity in less-developed countries, especially in countries with limited access to medical care and antibiotic therapy. [15, 16]
