Occupational Disease

occupational disease, any illness associated with a particular occupation or industry. Such diseases result from a variety of biological, chemical, physical, and psychological factors that are present in the work environment or are otherwise encountered in the course of employment. Occupational medicine is concerned with the effect of all kinds of work on health and the effect of health on a worker’s ability and efficiency.

Occupational diseases are essentially preventable and can be ascribed to faulty working conditions. The control of occupational health hazards decreases the incidence of work-related diseases and accidents and improves the health and morale of the work force, leading to decreased absenteeism and increased worker efficiency. In most cases the moral and economic benefits far outweigh the costs of eliminating occupational hazards.

This article discusses general occupational health hazards and the disorders they cause, as well as the role of occupational health services. More detailed information about specific disorders can be found in the articles dealing with human diseases and the structures of the human body, such as cancer; infection; and respiratory disease.
