Occupational asthma

Occupational asthma refers to asthma caused by exposure to asthma in the occupational environment. Its incidence is closely related to the degree of industrial development. In addition, its incidence is also related to the properties of asthma. For example, in workers who have been exposed to asthma isocyanates for a long time, the incidence of occupational asthma is about 5% to 10%. Among workers in the detergent industry who have been in prolonged contact with proteolytic enzymes, the incidence rate is 50% or higher. With the development of industry, the incidence of occupational asthma in our country is also increasing year by year. Specific bronchial provocation test is the most diagnostic method for the diagnosis of occupational asthma and the screening of occupational asthma. Avoiding contact with allergens is the most important measure in the treatment of occupational asthma.
