How is an occupational injury defined?

An occupational injury is typically defined as an event that results in harm or damage to an employee that occurs in the course of their work-related duties. This encompasses a broad range of incidents, including those that arise from systemic infections (such as exposure to harmful substances) or stress (like repetitive strain injuries).

A disease caused by systemic infections or stress that can result from the work environment fits squarely within this definition, as it highlights the impact of occupational factors on a worker's health. Recognizing various aspects of health beyond just acute injuries allows for a more comprehensive understanding of what constitutes an occupational injury, which potentially includes chronic conditions and diseases linked to the workplace.

In contrast, injuries from unexpected accidents, conditions caused by external forces, or injuries linked to physical exercise, while they can be work-related, do not fully capture the breadth of what can be classified as an occupational injury. It’s the inclusive perspective that acknowledges the influence of systemic factors and stressors in the workplace which makes "C" the most fitting definition.
