Provide an example of how Christian worldview can be integrated by a community health nurse when working with a population impacted by the communicable disease . The importance of a "buddy" when inside the patient care area and during donning and doffing, to ensure safe practice cannot be overstated, together with guidance from independent monitors if available. 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. February 2016 [internet publication]. http://www.ncbi.nlm.nih.gov/pubmed/29020589?tool=bestpractice.com. Finally, as illustrated by the Legionnaires disease outbreak in 1976, an extensive field investigation can fail to identify the cause, the source, and mode of spread in time to control the acute problem but still can enable advances in knowledge that ultimately lead to preventive measures (9). In such an instance, the response will be based on knowledge of possible continuing sources of norovirus or some other enteric pathogen, exposure in a restaurant, and removal of those sources. The severity of a specific problem is a principal determinant of the urgency and course of a field investigation and of any early intervention. On February 26, 2020, the Advisory Committee on Immunization Practices (ACIP)recommended pre-exposure prophylaxis vaccination with rVSV-ZEBOV for adults 18 years of age in the U.S. population who are at potential occupational risk of exposure to Zaire ebolavirus. https://www.who.int/news-room/detail/23-09-2019-second-ebola-vaccine-to-complement-ring-vaccination-given-green-light-in-drc. In his seminal article on criteria for assessing causal associations in epidemiology, Austin Bradford Hill concluded with a call for basing action on weighing the strength of the epidemiologic evidence against the severity of the consequences of delaying action and of taking premature action (1). Phase 2 placebo-controlled trial of two vaccines to prevent Ebola in Liberia. Immunization against infectious disease is a good example. Secondary prevention. Responses were largely maintained at 12 months. Preliminary control measures often can start on the basis of limited initial information and then be modified as investigations proceed. At this level health educators work to retrain, re-educate and rehabilitate the individual who has already had an impairment or disability. No patients who received the vaccine developed Ebola virus infection 10 days or more after randomization in the immediate-treatment arm; however, cases occurred in unvaccinated patients in the comparison group. This vaccine has not yet been approved by the FDA for routine use. Based on the target (individual vs population), disease stage, and risk factors (modifiable vs nonmodifiable), strategies can be categorized into 4 levels-health promotion (also known as primordial prevention), primary prevention, secondary prevention, and tertiary prevention. However, upstream approaches, e.g. Modify behavior to reduce risks to self or others. Breast self-examination is a good example of secondary prevention.

During epidemics, direct contact with any dead body should be avoided. [82]Centers for Disease Control and Prevention. In addition to severity, a spectrum of other factors influences the aggressiveness, extent, and scientific rigor of an epidemiologic field investigation. Crime prevention can be described in terms of three stages or levels - primary, secondary and tertiary prevention. 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. The criteria specified by Hilltemporality, strength of association, biologic gradient, consistency, plausibility, coherence, experiment, and analogyprovide a useful framework for assessing the strength of epidemiologic evidence developed during a field investigation.

Among certain sectorsfor example, the legal profession, private enterprise, and even regulatory agenciesacceptance of epidemiologic conclusions has been slower, in part because of the nature of causation in epidemiology: epidemiologic evidence establishes associations, not hard, irrefutable proof. The greater the severity, the sooner a public health intervention is expected. It is believed to occur naturally in specific animal populations that live in multiple sub-Saharan African countries. It helps block the virus from the cell receptor, preventing its entry into the cell. 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.
