What is the definition of an occupational disease?

An occupational disease is defined as a condition that is caused wholly or partially by the work environment or the specific tasks and duties performed in a job. This means that the disease can result from exposure to harmful substances, repetitive stress, accidents, or other work-related activities that may exacerbate or lead to health problems.

Choosing the option that identifies the disease as being caused, either entirely or partly, by work accurately captures the essence of what constitutes an occupational disease within the framework of workers' compensation and occupational health. Recognizing that work-related factors can interact with other variables to contribute to a health condition is crucial for understanding the implications in both medical assessments and legal contexts.

In contrast, other options describe conditions that are either unrelated to work, caused exclusively by genetic or environmental factors without any link to occupational activities, which do not align with the definition of occupational disease. Thus, the emphasis is on the relationship between a person's work and their health, which is central to the understanding of occupational diseases.
