2. Hypersensitivity Pneumonitis Hypersensitivity pneumonitis (HP), also called extrinsic allergic alveolitis, is a complex syndrome of varying intensity, clinical presentation, and natural history rather than a single, uniform disease HP represents an immunologic reaction to an inhaled agent, particularly an organic antigen, occurring within the pulmonary parenchyma. > 300 antigens spanning over a wide range of occupations have been described to cause HP. These antigens can be broadly classified into bacteria, fungi, animal proteins, plant proteins, low molecular weight chemicals, and metals. These exposures typically occur in specific occupations or hobbies but could also occur in the home and immediate environment.

Birds : 3.52 (95% CI: 2.29–5.40) Air-conditioners was 2.23 (95% CI: 1.59–3.14), Molds was 1.79 (95% CI: 1.23–2.60), Rural residence 1.64 (95% CI: 1.12–2.42), Air-coolers 1.45 (95% CI: 1.11–1.90), and Occupational exposure 1.39 (95% CI: 0.76–2.56) Exposure to Bird is important risk factors for HP, but.. is NOT THE ONLY ONE risk factor
