Threat/Vulnerability Assessment - Here, an in-depth assessment of the host, the agent, and the environment is carried out to analyze what attributes (for example, vaccination prevalence, recent epidemics, or access to safe water) might increase the risk of an epidemic among the displaced. Risk Assessment - Likelihood and magnitude of disease outbreaks are calculated and interventions are prioritized based on cost, availability of supplies, and so on. Even with this framework in place, however, the recent Cholera epidemic in Haiti shows that there is still work to be done in preventing disease outbreaks in IDP communities.  Part of the issue is the lack of availability of sufficient funding and access, both of which will be discussed further.
