According to the web of causation model of health and illness, the interaction between numerous causal variables creates a more potent combination of factors predisposing an in-dividual to illness. This implies:
1. Not only are there more variables, but the variables interact resulting in higher probability of illness.
2. One disease causes another, especially in vulnerable populations.
3. The greater the poverty, the more likely people are to have diseases.
4. Nurses should ensure that everyone is immunized because vulnerable populations spread disease.
