title: The identification of hypersensitivity pneumonitis.
abstract: The clinical history may point suspicion at a specific sensitizer. Brief, intermittent exposure produces acute, often reversible disease, frequently misdiagnosed as viral or bacterial pneumonia. Long-term exposure fuels the insidious development of chronic, disabling disease with minimal reversibility.
