Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Chandrakala Yannam, MD [2]
Overview
The world wide incidence of acute interstitial pneumonitis is approximately 97 cases per 100,000 individuals. The prevalence of acute interstitial pneumonitis is not known. Acute interstitial pneumonitis affects men and women equally. Acute interstitial pneumonitis occur typically previously healthy individuals in the age group of 50 to 55years.
