Farmer's lung disease(FLD) is a common form of occupational
hypersensitivity pneumonitis(HP)(also termed “greenhouse
lung”). FLD often occurs in greenhouse
farmers due to the long-term exposure to high
temperatures,
humidity, poor
air ventilation and high intensity of microorganism in
soils in the closed
environment of
greenhouses. Greenhouse
lung has a high disability rate and poor
prognosis if not diagnosed or treated in
time, which is a heavy burden to the society. Therefore, it is imperative to pay
attention to early identification and
epidemiological monitoring, and to evaluate the
disease burden, which is of great significance to formulating
public health measures to prevent the
disease.
