what are the three principles of outbreak management

Second, many investigators clinicians and non-clinicians find it useful to visit one or more patients with the disease. It is an axiom of field epidemiology that if you cannot generate good hypotheses (for example, by talking to some case-patients or local staff and examining the descriptive epidemiology and outliers), then proceeding to analytic epidemiology, such as a case-control study, is likely to be a waste of time. The five principles are designed to provide a framework for data governance for WHO. The management of pregnancy during antenatal care during virulent outbreaks should be guided by the following principles: Initial mandatory sensitivity screening test for all virulent infections such as Cholera, COVID-19, Ebola virus infection, and so on should conducted to rule out cases of infective patients. Yes. Salmonellosis associated with marijuana: a multistate outbreak traced by plasmid fingerprinting. an email from your counterpart at the National. List the six steps in an outbreak investigation. Other investigations, particularly those of a newly recognized disease or syndrome, begin with a relatively specific or narrow case definition. Epidemic is defined as - " the unusual occurrence of the disease or health related event in a community or region, clearly in excess of "expected occurrence". Or are new cases continuing to occur? Having a plan of action upon which everyone agrees will allow you to hit the ground running and avoid delays resulting from misunderstandings. Because the Fisher Exact Test is tedious to calculate, let Epi Info or another computer program perform the calculations for you. 2009 Aug;5(8):e1000471. Outbreak Management Ossama Rasslan Key Points Outbreaks of infection should be clearly defined, identified, and promptly investigated because of their importance in terms of morbidity, cost, improvement of patient care, and institutional image. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. Unable to load your collection due to an error, Unable to load your delegates due to an error. The Epiville SARS outbreak is localized within the Amoy Apartments complex and Star Hospital, with an onset from 10th August to 23rd August 2003, and disproportionately affects older individuals above the age of 50. Consider, for example, the outbreak of hepatitis A illustrated by the epidemic curve in Figure 6.5. Torok TJ, Tauxe RV, Wise RP, Livengood JR, Sokolow R, Mauvais S, et al. Upon confirmation of the outbreak, an outbreak response team and management plan is developed. If you only had data through Week 35, that is, through point A, you might conclude that the outbreak is still on the upswing, with more cases to come. There are three types of transmission-based precautions: contact precautions, droplet precautions and airborne precautions. Tidsskr Nor Laegeforen. Examples of exclusion policies that may be implemented to prevent the transmission of infection during an outbreak include: Restricted movement of residents within the facility will assist with the reduction of transmission. Principles of Outbreak Investigations Be systematic! Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Some societies use Oxford Academic personal accounts to provide access to their members. Adapted from: European Programme for Intervention Epidemiology Training [Internet]. (42) At which meal do you think the critical exposure occurred? Infect Control Hosp Epidemiol 2003;24:84852. Copyright 201822 : Bug Control (Aust) Pty Ltd and Bug Control New Zealand Ltd. All rights reserved. Implement additional precautions immediately. HACCP is a systematic approach to the identification, evaluation, and control of food safety hazards based on the following seven principles: Principle 1: Conduct a hazard . Thus, the investigators were forced to develop new hypotheses about a source of Legionnaires disease to explain this outbreak. (28) In a line listing, each column represents an important variable, such as name or identification number, age, sex, case classification, etc., while each row represents a different case. The itineraries were similar. You must arrange travel, lodging, and local transportation. government site. A case might be temporarily classified as probable or possible while laboratory results are pending. The principles are intended primarily for use by WHO staff across all parts of the Organization in order to help define the values and standards that govern how data that flows into, across and out of WHO is collected, processed, shared and used. In this outbreak, the association between eating beef at the banquet and gastroenteritis was both strong (RR=5.7) and statistically significant (p < 0.001). Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Verifying the diagnosis is important: (a) to ensure that the disease has been properly identified, since control measures are often disease-specific; and (b) to rule out laboratory error as the basis for the increase in reported cases. through the air, via a vector, via contaminated food or water, or during unprotected sexual intercourse. An outbreak or an epidemic is the occurrence of more cases of disease than expected in a given area or among a specific group of people over a particular period of time. Figure 6.4 Number of Cases of Acute Hemorrhagic Conjunctivitis, By Month and Week of Report Puerto Rico, August 7October 30, 2003. In an attachment, you found an official laboratory report from the Upper Northern . Return to text. Fortunately, for a rare disease such as legionellosis and most other outbreak-associated diseases, the odds ratio from a case-control study approximates the relative risk that would have been found if a cohort study had been feasible. If the control group is systematically different from the case group in certain ways, a true association between exposure and disease may be missed or a spurious association may be observed between a non-causal exposure and disease. Whichever decision you make, you may be right or you may be wrong. Describe the principles of outbreak management Describe different methods of outbreak management as they pertain to the epidemiological triad (i.e., host, agent and environment). For some diseases, date of onset is sufficient. Free access to premium services like Tuneln, Mubi and more. Case definitions: meningococcal disease and viral meningitis. This turned out to be the exact period during which a restaurant employee, diagnosed with hepatitis A in mid-October, would have been shedding virus while still working. By accepting, you agree to the updated privacy policy. Ensure responsibility is assigned to one person on each unit for screening accountability. - Follow the same steps for every type of outbreak - Write down case definitions - Ask the same questions of everybody Stop often to re-assess what you know - Line list and epi curve provide valuable information; many investigations never go past this point Presented at 53rd Annual Epidemic Intelligence Service Conference, April 1923, 2004, Atlanta. JAMA 1997;278:38995. As a result, investigators often create different categories of a case definition, such as confirmed, probable, and possible or suspect, that allow for uncertainty. The clinical criteria should be based on simple and objective measures such as fever 40C (101F), three or more loose bowel movements per day, or myalgias (muscle pain) severe enough to limit the patients usual activities. This approach ensures that the investigation proceeds without missing important steps along the way. The affected population had a greater proportion of persons who were black, female, young, and less likely to smoke than persons in a typical Legionnaires outbreak. In general, control measures are usually directed against one or more segments in the chain of transmission (agent, source, mode of transmission, portal of entry, or host) that are susceptible to intervention. J Epidemiol Comm Health 1989;43:3114. What vehicles are commonly implicated? Source Castel AD, Blythe D, Edwards L, Totaro J, Shah D, Moore M. A large outbreak of Salmonella Enteritidis infections associated with crabcakes at a church fundraiserMaryland, 2003. A case definition is a standard set of criteria for deciding whether an individual should be classified as having the health condition of interest. Start at the earliest case of the epidemic and count back the minimum incubation period, and note this date as well. Who is in charge? Figure 6.5 Hepatitis A from Sub Shop Massachusetts, 2001. In a large community outbreak of botulism in Illinois, investigators used three sequential case-control studies to identify the vehicle. 1 Principles of Outbreak Management 2 Definition of outbreak Occurrence of more cases of disease than expected in a given area among a specific group of people over a particular period of time or Two or more linked cases of the same illness 3 Objectives of outbreak investigations To control continuing outbreaks To prevent future outbreaks Return to text. 11.3.4 Outbreak management team - communication requirements . The investigation of an outbreak is based on a multidisciplinary approach (clinical, epidemiological, environmental, and microbiological) with a descriptive and analytical (hypothesis testing) phase. Odds ratios. In a similar fashion, if the time of exposure and the times of onset of illness are known but the cause has not yet been identified, the incubation period can be estimated from the epidemic curve. Understand principles of Legionella outbreak investigation. Epub 2009 Aug 21. Presented at 53rd Annual Epidemic Intelligence Service Conference, April 1923, 2004, Atlanta. Potentially correlated events can be noted on the graph. For example, if one of the hypotheses under consideration is that persons who worked in the west wing were at greater risk of disease, do not define a case as illness among persons who worked in the west wing with onset between Instead, define a case as illness among persons who worked in the facility with onset between Then conduct the appropriate analysis to determine whether those who worked in the west wing were at greater risk than those who worked elsewhere. )epidemiological investigation doc. A newer edition of this book is available. Education, child protection, commerce, transportation, and human rights have all suffered. Case Definitions Meningococcal Disease. If you believe you should have access to that content, please contact your librarian. The lesson learned is that when the epidemiology does not fit the usual or natural patterns of transmission, investigators should think about intentional modes of transmission. Centers for Disease Control and Prevention. These skills improve with practice and experience. Division of work Division of work, also known as division of labour, involves dividing a job into individual tasks. Principles of Outbreak invEstigation. The descriptive epidemiology may provide useful clues that can be turned into hypotheses. This also leads to specialization, accuracy, and speed in the workforce. For librarians and administrators, your personal account also provides access to institutional account management. New Engl J Med 1992;326:11737. Outbreak Protocol is provided for health practitioners to aid in the detection and control of communicable disease outbreaks by providing a framework of provincial legislation and policy. Refer to hospital transfers. In fact, any sudden rise in the number of cases suggests sudden exposure to a common source one incubation period earlier (Figure 6.3). When local data are not available, a health department may use rates from state or national data, or, alternatively, conduct a telephone survey of physicians to determine whether they are seeing more cases of the disease than usual. For example, in an outbreak of hypervitaminosis D that occurred in Massachusetts in 1991, investigators found that all of the case-patients drank milk delivered to their homes by a local dairy. Details of suppliers should be included in the outbreak management plan. Effective outbreak management requires a multidisciplinary approach and involves individuals with different responsibilities. Limited essential equipment and furniture should be placed within the affected room/s or area/s during an outbreak. Using the dates of onset listed below, draw an epidemic curve. Steps in the Epiville SARS Outbreak Investigation. The causative infectious disease will govern which precautions should be implemented. Next, compute a measure of association, such as a risk ratio or odds ratio. Separate staff should be allocated to affected or non-affected residents where possible. In a third study, investigators used radio broadcast appeals to identify healthy restaurant patrons who had eaten the implicated sandwich. More details regarding standard and transmission-based precautions can be obtained from the relevant sections of the manual. Fraser DW, Tsai TF, Orenstein W, Parkin WE, Beecham HJ, Sharrar RG, et al. In theory, a propagated epidemic one spread from person-to-person with increasing numbers of cases in each generation should have a series of progressively taller peaks one incubation period apart, but in reality few produce this classic pattern. When this is unable to be accommodated then residents with the same organism may need to be accommodated/cohorted in a shared room together. Download. In analytic epidemiology, inclusion of false-positive cases can produce misleading results. Therefore, the epidemic curve can be used to identify the likely period of exposure. Subtracting 2 weeks from the week of October 28 points to the week of October 14. Return to text. Standard plus appropriate transmission-based precautions are to be implemented as soon as an outbreak or a potential outbreak has been identified or determined. The expected number is usually the number from the previous few weeks or months, or from a comparable period during the previous few years. Investigators may conduct what is sometimes called stimulated or enhanced passive surveillance by sending a letter describing the situation and asking for reports of similar cases. For example, the outbreak of West Nile virus in Queens, New York, in 1999 was promptly investigated to determine the extent of the outbreak and risk factors for disease so appropriate control measures could be developed and implemented. If the epidemic curve points to a narrow period of exposure, what events occurred around that time? A 95% confidence interval, the interval used most commonly by epidemiologists, corresponds to a p=0.05 cut-off. A large community outbreak of waterborne giardiasis-delayed detection in a non-endemic urban area. Presented at 53rd Annual Epidemic Intelligence Service Conference, April 1923, 2004, Atlanta. Snow on cholera. Detection, isolation, and molecular subtyping of. Investigators of an outbreak of salmonellosis in The Dalles, Oregon, were stumped when they were able to implicate salad bars in several local restaurants, but could not identify any common ingredients or distribution system. 1. Consider again the gastroenteritis data in Table 6.8. Malimu principles of outbreak investigation, (E pi !! 3. For example, in an outbreak of listeriosis in 2002 caused by contaminated sliceable turkey deli meat, announcements in the media alerted the public to avoid the implicated product and instructed them to see a physician if they developed symptoms compatible with the disease in question.(27). Those that may be essential will need to be discussed with the provider. In other words, they should be similar to the cases except that they dont have the disease. A p-value this small indicates that the null hypothesis is highly improbable, and the investigators rejected the null hypothesis. The shape of the epidemic curve may provide clues about the pattern of spread in the population, e.g., point versus intermittent source versus propagated. The term "outbreak" is used for a small usually localized epidemic. The attack rate is low among those not exposed, so the difference or ratio between attack rates is high. In other words, epidemiologists cannot afford to conduct an investigation that is quick and dirty. They must conduct investigations that are quick and clean.(22) Under such circumstances, epidemiologists find it useful to have a systematic approach to follow, such as the sequence listed in Table 6.2. In other situations, the media may have already spread the word. Subtract the time of onset of the median case from the time of exposure to estimate the median incubation period. If you have questions about the laboratory findings (for example, if the laboratory tests are inconsistent with the clinical and epidemiologic findings), ask a qualified laboratorian to review the laboratory techniques being used. Section B2.8: Transmission-Based Precautions: D.8: Environmental Cleaning: When to Use Detergent and Disinfectant, Section D.10: Environmental Cleaning: Cleaning of Isolation/Outbreak Rooms, Section B2.5: Management of the Resident in Isolation, Section B2.6: Transmission-Based Precautions: Procedure for the Setting Up and Management of An Isolation Room, Section B1.10: Standard Precautions: Safe Management of Soiled Linen, Section B1.9: Safe Disposal of Clinical/Contaminated Waste, excluding residents or cancelling therapies and recreational activities, restriction or exclusion of visitors to residents, restricting facility access to essential personnel only, restriction or cancellation of volunteer programmes, exclusion of staff who are unwell; depending on the infectious disease, this may also involve exclusion and isolation of their close contacts. : Yes; Lab Results: WB IgG+; Comments: Arthritis, arthralgias, headache, fatigue, sweats, chills; Physician Reporting: Dr. Howard; Phone: 555-1950; Date of Report: 11/24/06. Outbreaks may occur for a number of reasons including: introduction and transmission of an infectious disease within the healthcare site, lapses in infection control practices, contaminated or defective products or devices, and establishment of a reservoir for a pathogen somewhere in the healthcare facility. The odds ratio for Grocery Store A is calculated as: An odds ratio of 11 is quite large, indicating that shopping at Grocery Store A was strongly associated with developing legionellosis. This aggregation of cases seems to be unusual, but frequently the public (and sometimes the health agency) does not know the denominator. The numbering scheme for this step is problematic, because preparing for field work often is not the first step. Are the clinical features consistent with the diagnosis? Perl defined five key elements of health care outbreak response that other speakers commented on throughout this section: outbreak management; care of large numbers of critically ill patients; protection of health care workers, patients, and volunteers; communication with health care workers, patients, families, community members, and public health . Source: Pan American Health Organization. The hypothesis that the locally produced ground beef was the vehicle could easily be tested by asking case-patients and controls (persons without thyrotoxicosis or other thyroid disease) whether they ate ground beef from the same source. Often, a spot map by site of presumed exposure is more informative than one by residence. In an outbreak context, hypotheses are generated in a variety of ways. Third, summarize the clinical features using frequency distributions. The earlier the outbreak is detected and investigated in close relation with public health authorities, the greater will be the potential preventive impact of control measures. Describe an epidemic in terms of person, place and time. Step 10: follow-up to ensure implementation of control measures, Cooperation for international outbreak investigation and preparedness, Methodology of intervention trials in individuals, Methodological issues in the design and analysis of community intervention trials, Community intervention trials in high-income countries, Community-based intervention trials in low- and middle-income countries, Validity and bias in epidemiological research, Measuring the health of populations: the Global Burden of Disease study methods, Mathematical models of transmission and control of infectious agents, Sociology and psychology in public health, Health promotion, health education, and the publics health, Development and evaluation of complex multicomponent interventions in public health, Economic appraisal in public healthcare: assessing efficiency and equity, Governance and management of public health programmes, Implementation science and translational public health, Environmental and occupational health sciences, Environmental health issues in public health, Environmental exposure assessment: modelling air pollution concentrations, Toxicology and risk assessment in the analysis and management of environmental risk, Epidemiology and prevention of cardiovascular disease, Chronic obstructive pulmonary disease and asthma, Neurological diseases, epidemiology, and public health, Chronic hepatitis and other liver disease, Prevention and control of public health hazards, Public health aspects of illicit psychoactive drug use, Injury prevention and control: the public health approach, Interpersonal violence: a recent public health mandate, Urban health in low- and middle-income countries, Ethnicity, race, epidemiology, and public health, Forced migrants and other displaced populations, Prisons: from punishment to public health, Prevention and control of non-communicable diseases, Strategies and structures for public health intervention, Training of public health professionals in developing countries, Training of local health workers to meet public health needs, Emergency public health and humanitarian assistance in the twenty-first century, Principles of public health emergency response for acute environmental, chemical, and radiation incidents, The future of international public health in an era of austerity, Oxford University Press makes no representation, express or implied, that the drug dosages in this book are correct. By asking about drug use in a second case-control study, the investigators implicated marijuana as the likely vehicle. Similarly, to control an outbreak of influenza-like illness in a nursing home, affected residents could be cohorted, that is, put together in a separate area to prevent transmission to others. Do they know anyone else with the disease? Vaccinations promote development of specific antibodies that protect against infection. As noted in Step 1, development of a communications plan and communicating with those who need to know during the investigation is critical. From an epidemiologic point of view, hypotheses are evaluated in one of two ways: either by comparing the hypotheses with the established facts or by using analytic epidemiology to quantify relationships and assess the role of chance. Alginate bags are to be used for all soiled, wet and contaminated laundry. Public Health Reports 2003; 118:928. Epub 2008 Nov 14. In that investigation, a case-control study failed to implicate any plausible food source as a common vehicle. (That is, do all of the cases occur with one incubation period?). 4. This illustrates an important axiom of field epidemiology: Get it while you can. Source: Jani AA, Barrett E, Murphy J, Norton D, Novak C, Painter J, Toney D. A steamship full of trouble: an outbreak of Salmonella Typhimurium DT 104 gastroenteritis at a holiday banquetVirginia, 2003. The controls provide the level of exposure you would expect to find among the case-patients if the null hypothesis were true. List different surveillance methods used to ascertain cases. When the epidemiology does not fit the natural pattern, think unnatural, i.e., intentional. Fortunately, potential controls are usually plentiful. Guiding Principles for Outbreak Management Arrangements 3 | P a g e Purpose of document This document is intended to outline principles for the design of COVID-19 Local Outbreak Plans led by the Director of Public Health at Upper Tier Local Authority level, working with Nash D, Mostashari F, Fine A, Miller J, OLeary D, Murray K, et al. Disclaimer, National Library of Medicine A cohort study is feasible only when the population is well defined and can be followed over a period of time. New Engl J Med 1982;306:124953. Verify diagnosis 4. JAMA 1985;253:12758. These incubation periods can be compared with a list of incubation periods of known diseases to narrow the possibilities. Is this epidemic curve consistent with a point-source epidemic? Standard plus appropriate transmission-based precautions are to be implemented as soon as an outbreak or a potential outbreak has been identified or determined. Ungchusak, Kumnuan, and Sopon Iamsirithaworn. Some simple and effective strategies protect portals of entry. For other diseases, particularly those with a relatively short incubation period, hour of onset may be more suitable (see Lesson 6). 1996 Nov 20;116(28):3329-34. Traditionally, a special type of histogram is used to depict the time course of an epidemic. Although teachers and other adult chaperones accompanied the students on both tours, no adult reported illness. As noted earlier, the severity of the illness, the potential for spread, availability of control measures, political considerations, public relations, available resources, and other factors all influence the decision to launch a field investigation. Cookies used to make website functionality more relevant to you. Public health dispatch: outbreak of listeriosis northeastern United States, 2002. You could calculate a p-value that is not less than 0.05 and consequently fail to reject the null hypothesis, which may turn out to be true. This document outlines the ethical principles that should guide communication planning and implementation at every level from frontline workers to policymakers. In fact, often these two steps are addressed at the same time. If so, effective disease control and prevention measures must be implemented in these new areas. If an outbreak affects a restricted population such as persons on a cruise ship, in a school, or at a work site, and if many cases are mild or asymptomatic and therefore undetected, a survey of the entire population is sometimes conducted to determine the extent of infection. Investigating an outbreak requires a combination of diplomacy, logical thinking, problem-solving ability, quantitative skills, epidemiologic know-how, and judgment. Referring to Table 6.10, a chi-square of 13.02 corresponds to a p-value less than 0.001. If exposure is much more common among the case-patients than among the controls, i.e., the observed exposure among case-patients is greater than expected exposure provided by the controls, then exposure is said to be associated with illness. A timely investigation has for aim to identify the source and vehicle of the outbreak and provides unique opportunities to better understand its occurrence and the role of contributing risk factors to implement the most appropriate measures to control it and prevent further recurrences. 1.
