Answer

As a group, diffuse interstitial diseases of the lung are uncommon. Based on the Bernalillo County, NM, USA registry data published in 1994, the overall estimated incidence is approximately 30 cases per 100,000 persons per year. [2]  Rates of interstitial lung disease are somewhat higher in men than in women, and the epidemiology is markedly affected by age and occupational exposures. Of patients referred to a pulmonary disease specialist, an estimated 10-15% have a DPLD.
