In this chapter, the model used to systematically identify and characterize the spectrum of intervention options for outbreaks and other acute health threats focuses on two basic biologic and environmental dimensions: (1) interventions that can be directed at the source(s) of most infectious and other disease-causing agents and (2) interventions that can be directed at persons susceptible to such agents (Box 11.2). There are different ways of categorizing crime prevention efforts.

Under such circumstances, the primary objective of the field investigation is to use the scientific principles of epidemiology to determine a rational and appropriate response for ending or controlling the problem. Primary prevention strategies focus on a population the does not have a disease that an initiative is trying to prevent. Consequences to consider include the most common symptoms and syndrome caused, duration of illness, complications including hospitalization and case-fatality rates, need for treatment, and economic impact. http://www.ncbi.nlm.nih.gov/pubmed/29153266?tool=bestpractice.com, In addition to these interventions, psychological support is needed for healthcare workers exposed to dangerous pathogens. These examples underscore the practical challenges in balancing the need to assess causality through the process of scientific inquiry with the potentially conflicting need to intervene quickly to protect the publics health.

Primary crime prevention is directed at stopping the problem before it happens. The type(s) and number of interventions used might evolve as a function of incremental gains in information developed during the investigation. For ease of comprehension, we group the levels of engagement into those that are primary, secondary, and tertiary, deliberately using the same language used for the familiar public health levels of prevention. One example is botulism, which is a low-probability but high-consequence event. Secondary prevention includes those measures that lead to early diagnosis and prompt treatment of a disease.

These determinants, which might be both interrelated and not mutually exclusive, encompass a constellation of factors (e.g., specific knowledge of causative etiologic agent[s] and of reservoirs or mode[s] of acquisition or spread) and recognition of other causal determinants as reflected, in part, by assessing the investigations ability to address the causation criteria (see the following section). A two-dose vaccine regimen of a different vaccine that was also designed to protect against the Zaire ebolavirus species of Ebola was used under a research protocol in 2019 during an Ebola outbreak in the Democratic Republic of the Congo.
