Pneumoconiosis primarily arises from chronic exposure to minerals and dusts, such as those encountered in mining, excavation, or the processing of jade and stone. Workers in these industries, over long periods, inhale these dust particles which accumulate in the lungs, eventually merging and irritating the pulmonary system. This results in the formation of extensive fibrosis that encapsulates the dust particles, ultimately leading to the development of pneumoconiosis. Pneumoconiosis itself is not classified as an infectious disease but rather as an occupational disease. Therefore, there is no need to isolate patients with pneumoconiosis. However, patients should be removed from their work environments and avoid further exposure to dusts or fumes to prevent the exacerbation of their condition.
