Asbestosis — occupational disease The lung disease asbestosis is caused primarily by prolonged inhalation of asbestos fibers. It occurs mainly among workers whose occupations involve exposure to asbestos and people who live near mines, factories, and construction sites.

Occupational diseases and occupational injuries are distinct categories of health problems encountered in the workplace, though both are central concerns of occupational medicine.

Occupational Disease: This refers to any illness or health condition associated with a specific job or industry. These conditions typically result from prolonged exposure to various biological, chemical, physical, or psychological factors present in the work environment. Because these diseases often develop over time, they can be difficult to diagnose, as they may mimic illnesses from non-occupational causes. Examples include respiratory diseases caused by inhaling dusts, such as pneumoconiosis or asbestosis.1234
Occupational Injury: This is defined as any bodily damage or health problem resulting directly from activities undertaken at the workplace. Unlike the often gradual onset of occupational disease, injuries are typically the result of immediate, identifiable events or accidents. High-risk environments, such as mining, construction, or the operation of heavy machinery, are frequently associated with these traumatic incidents.53

While both are preventable through proper safety standards and hazard control, occupational injuries are often more "spectacular" and easier to track, whereas occupational diseases may go unrecognized for years due to the time required for symptoms to manifest.53
