Of these types, Farmer's Lung and Bird-Breeder's Lung are the most common. "Studies document 8-540 cases per 100,000 persons per year for farmers and 6000-21,000 cases per 100,000 persons per year for pigeon breeders. High attack rates are documented in sporadic outbreaks. Prevalence varies by region, climate, and farming practices. HP affects 0.4-7% of the farming population. Reported prevalence among bird fanciers is estimated to be 20-20,000 cases per 100,000 persons at risk." [3]
Treatment[edit]
The best treatment is to avoid the provoking allergen, as chronic exposure can cause permanent damage.Corticosteroids such as prednisolone may help to control symptoms but may produce side-effects.[18]
