For any given problem, the type(s) and number of interventions to be implemented will vary, depending on the nature of the acute problem, including its cause, mode of spread, and other factors. At this level health services workers can work to retrain, re-educate and rehabilitate people who have already developed an impairment or disability. Modify the affected environment through vector control. Because of differences in knowledge, beliefs, and perceived impact of the outbreak, each group might draw different conclusions about causality from the same information. Primary prevention includes those measures that prevent the onset of illness before the disease process begins. Use of post-exposure prophylaxis after occupational exposure to Zaire ebolavirus. Clinical management of patients with viral haemorrhagic fever: a pocket guide for the front-line health worker. Ebola Virus Disease - WebMD Similarly, clusters of a healthcare-associated infectionespecially among postsurgical or immunocompromised patientsare often investigated because of the potential for serious complications and greatly prolonged hospitalization, the possibility of iatrogenic illness as an avoidable medical event, and the immediate need to resolve questions about the safety of continuing to admit patients to the hospital (2).

Public health officials who have responsibility and legal authority for making decisions about interventions should consider certain key principles: selecting the appropriate intervention, facilitating implementation of the intervention, and assessing the effectiveness of the intervention (Box 11.1). Another approach to classificationas universal, selective, or indicated preventive interventionsrelates to who receives the intervention.

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. 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. 2017 Oct 12;377(15):1438-47. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5705229, http://www.ncbi.nlm.nih.gov/pubmed/29020589?tool=bestpractice.com.

During the Ebola virus disease epidemic in 20142015, public health officials in the United States used a combination of intervention measures directed at persons in whom Ebola virus disease was diagnosed (isolation), at their close contacts (active monitoring, quarantine, or restrictions on travel), at those providing healthcare to them (training in correct use of special protective gear and active monitoring), and at those arriving from selected countries (screening or active monitoring) (20).

Health Education can be applied at all three levels of disease prevention and can be of great help in maximizing the gains from preventive behavior. Assessing causality at each step in an investigation is important not only for assessing the strength of evidence developed up to that point, but also in helping to identify what evidence is missing or requires further attention and for planning additional approaches (e.g., data gathering and analysis) essential for supporting decisions regarding interventions. Exclude unvaccinated persons from cohorts of vaccinated persons. Healthcare workers suspected of being infected should be isolated and treated the same as any other patient until a negative diagnosis is confirmed. Avoid funeral or burial practices that involve touching the body of someone who died from EVD or suspect EVD. Primary prevention stops violence before it occurs.

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. These levels of prevention were first described by Leavell and Clark3 and continue to provide a useful framework to describe the spectrum of prevention activities. 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. 2015 Nov;15(11):1300-4. https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(15)00228-5/fulltext, http://www.ncbi.nlm.nih.gov/pubmed/26321189?tool=bestpractice.com, From the personal collection of Chris Lane, MSc (Public Health England/World Health Organization); used with permission.
