Which aspect is NOT a part of a host in the public health model?

In the context of the public health model, the host refers to the individual who is at risk of a health issue, such as addiction. This model takes into account various aspects that can influence an individual’s susceptibility to health problems, including their personal characteristics, behaviors, and the broader social and cultural environment surrounding them.

The physiological symptoms of addiction primarily refer to the physical manifestations of the condition and are more closely associated with the illness itself, rather than the characteristics of the host. The host elements generally include the social context in which an individual lives, such as their relationships and support systems; the individual's own attributes like genetics, personality traits, and behaviors; and the cultural norms that shape the behaviors and perceptions of a community. These factors help to paint a complete picture of the host's environment and influences but do not explicitly include the physiological symptoms, which are a direct consequence of the health issue rather than a characteristic of the host.
