Overview
The incidence and prevalence of hypersensitivity pneumonitis varies depending on various factors like season, occupation etc.Hypersensitivity pneumonitis usually affects patients in fourth to sixth decade of life.The mean age at diagnosis is 53 +/- 14 years.There is no racial predilection to hypersensitivity pneumonitis. Hypersensitivity pneumonitis affects men and women equally. Death due to Hypersensitivity pneumonitis is reported more in men.
Epidemiology and Demographics
Incidence
- The incidence rate of hypersensitivity pneumonitis varies depending on various factors like season, occupation etc. [1]
Prevalence

- These are as following:
- Farmers:
- Pigeon Breeders: 6000-21,000 cases per 100,000 persons per year
- Bird Fanciers: 20-20,000 cases per 100,000 persons per year
Age
- Hypersensitivity pneumonitis usually affects patients in fourth to sixth decade of life.
- The mean age at diagnosis is 53 +/- 14 years.[6]
Race
- There is no racial predilection to hypersensitivity pneumonitis.
Gender
- Hypersensitivity pneumonitis affects men and women equally.
- Death due to Hypersensitivity pneumonitis is reported more in men.[7]
