For most gastrointestinal outbreaks, selecting control measures depends on knowing whether transmission has resulted from person-to-person, foodborne, or waterborne spread and, if either of the two latter modes, on identifying the source. 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).

Secondary Prevention Immediate responses after violence has occurred to deal with the short-term consequences of violence. Primary prevention. Public health interventions should be scientifically driven on the basis of established facts and data, current investigation findings, and knowledge from previous investigations and studies. If there is a partial or total breach in PPE (e.g., gloves separate from sleeves leaving exposed skin, a tear develops in an outer glove, a needlestick) during patient care, the healthcare worker must move immediately to the doffing area to assess the exposure and implement the facility exposure plan, if indicated. During early stages, interventions based on established guidelines for disease control can be applied.

Taking these factors into account, the following actions should be reconsidered at each progressive stage of the field investigation: Adherence to these and other steps during epidemiologic field investigations can be integral to helping attain and optimize a scientifically rational basis for selecting and implementing public health interventions for controlling or terminating a problem. When the problem is identified initially, the levels of certainty about the etiology, source, and mode of spread can range from known to unknown (Figure 11.1). ATOD prevention is categorized by three types of strategies: Primary, Secondary, and Tertiary prevention. [81]WHO: Ebola virus disease: vaccines. Opens in new window. During epidemics, direct contact with any dead body should be avoided.

Emphasis of the primary prevention is, besides a sufficient calcium intake, to omit risk factors; with secondary prevention the use of medical treatments such as estrogens/gestagens, bisphosphonates, and recently also SERMs is applied. A useful framework that takes a stratified approach to exposure risk has been proposed. Lancet Infect Dis.

It may also be considered in patients with intact skin-only contact with an infected patient (alive or deceased) or their body fluids. Epidemiology, in particular field epidemiology, is a relatively young scientific discipline in the medical world, acquiring academic, and then public, acceptance only gradually over the past five to six decades. Although a single criterion might not be convincing in a given context or fully accepted on the basis of the interpreters viewpoint, a combination of well-assessed criteria pointing to a common exposure can strengthen confidence and facilitate support for directed interventions.

In contrast, attorneyswho either are representing plaintiff-patrons who putatively acquired their illnesses as a result of restaurant exposure or are defending a restaurant epidemiologically associated with a foodborne illness epidemicwill approach such a problem by using a legal framework for causation, which varies from epidemiologic causation (12). Meanwhile, epidemiologic evidence often is the first basis for implicating a causative agent or mode of spread before the results of more in-depth and lengthier scientific investigations become available to support decision-making about interventions. J Infect Dis. Relative emphasis of investigative and control efforts (intervention options) in disease outbreaks as influenced by levels of certainty about etiology and source or mode of transmission.
