Occupational disease refers to the diseases caused by workers in enterprises, institutions and individual economic organizations who are exposed to dust, radioactive substances and other toxic and harmful substances in their professional activities.
Occupational disease is a man-made disease. Its incidence and prevalence directly reflect the level of disease prevention and control.
The definition of occupational disease by the World Health Organization has not only medical meaning, but also legislative meaning, that is, the "statutory occupational disease" stipulated by the state.
