In this model, the worker is considered the host because they are the individual who is exposed to various agents (such as chemical, physical, biological, or ergonomic hazards) in their work environment.

Understanding this relationship is crucial as the health outcomes of workers can be significantly influenced by the exposure to these agents. Identifying the worker as the host emphasizes the importance of assessing individual vulnerabilities, existing health conditions, and the potential for the development of occupational illnesses. This perspective allows health professionals, including occupational health nurses, to implement targeted interventions aimed at protecting the workforce, promoting health, and preventing workplace injuries.

While the workplace environment, the occupational health nurse, and the employer play critical roles in the overall occupational health framework, they are not classified as the host in this context. The environment acts as the setting where exposure occurs, the occupational health nurse provides care and interventions for the workers, and the employer is responsible for creating a safe and healthy workplace. However, it is the worker who is directly impacted by these factors, which is why
