Before leaving for a field investigation, consult laboratory staff to ensure that you take the proper laboratory material and know the proper collection, storage, and transportation techniques. If you need specialized laboratory work such as confirmation in a reference laboratory, DNA or other chemical or biological fingerprinting, or polymerase chain reaction, you must secure a sufficient number of appropriate specimens, isolates, and other laboratory material as soon as possible. The epi curve shows the magnitude of the epidemic over time as a simple, easily understood visual. For full access to this pdf, sign in to an existing account, or purchase an annual subscription.

Presented at 51st Annual Epidemic Intelligence Service Conference, April 2226, 2004, Atlanta. Once the decision to conduct a field investigation of an acute outbreak has been made, working quickly is essential as is getting the right answer. The reader will learn about the major ten steps in the investigation, with examples, which starts by confirming the existence of the outbreak, verifying the diagnosis, gathering case information, descriptive epidemiology, formulating and testing the hypothesis when necessary, conducting environmental surveys to supplement epidemiological evidence, and providing timely on-site reporting of the findings, with practical recommendations to local and national responsible authorities. Is the number of new cases slowing down or, better yet, stopping? By accepting, you agree to the updated privacy policy. In other words, they should be similar to the cases except that they dont have the disease. (34) The most cases occurred in Washburn (n=21) and Chippewa (n=17) Counties. Yes. The investigation of an outbreak is an evolving process: information gathered or conclusions made at a given stage must be fully used for following steps. If the map shows a cluster or other pattern (such as cases along a road), the investigator must consider possible explanations perhaps water supplies, wind currents, or proximity to a restaurant or grocery. Lower respiratory infections are the third leading causes of death worldwide (World Health Organization (WHO) 2008 ). Often, a spot map by site of presumed exposure is more informative than one by residence. Presented at 53rd Annual Epidemic Intelligence Service Conference, April 1923, 2004, Atlanta. PPE must be worn by cleaning staff when cleaning isolation rooms during an outbreak. Infection can be caused by bacteria, fungi, viruses or prions and can affect almost all body systems. Referring to Table 6.10, a chi-square of 13.02 corresponds to a p-value less than 0.001. Weed and pest animal management is an integral part of managing natural resources and agricultural systems. For example, bed nets are used to protect sleeping persons from being bitten by mosquitoes that may transmit malaria. Four public health issues were considered: prevention measures, self-health evaluation, SARS knowledge, and appraisal of crisis management. MMWR 2004;53:6324. A spot map is a simple and useful technique for illustrating where cases live, work, or may have been exposed. 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. You indicated this topic was not helpful to you Could you please leave a comment telling us why? Presentation Transcript. Nursing home staff did report that the 2 residents of the south wing who developed pneumonia did spend much of their time in the north wing. Readers must therefore always . Presented at 53rd Annual Epidemic Intelligence Service Conference, April 1923, 2004, Atlanta. Outcomes of treated human granulocytic ehrlichiosis cases. External appointments will need to be reviewed. (35) Specifically, the epidemic curve indicated that the outbreak was basically over, because no new case had been reported in the previous two weeks. This assumption is known as the null hypothesis. Only approved chemicals should be used in accordance with facility cleaning protocols. Some interventions are aimed at blocking the mode of transmission. The cases that stand apart may be just as informative as the overall pattern. Describe the principles of outbreak management 1. Risk is a core principle in financial management. Principle 1: Think broadly about risk. Unable to load your collection due to an error, Unable to load your delegates due to an error. Are intervention measures working? You may recall that the investigation of pneumonia among attendees of an American Legion conference in Philadelphia in 1976 that gave Legionnaires disease its name was not considered complete until a new organism was isolated in the laboratory some six months later.(48). 4. Roehrig JT, Nash D, Maldin B, Labowitz A, Martin DA, Lanciotti RS, et al. Adequate supplies of PPE will need to be available for initial set-up, as well as ongoing use during the outbreak. Neutral detergent and hospital-grade disinfectant should be readily available. Salem, VA; County: Columbia; Sex: Male; Race: black; Disease: Lyme Disease; Date of Onset: 2005; Lab Confirmed? Even if the cases turn out to be the same disease, the number of cases may not exceed what the health department normally sees in a comparable time period. Why are some groups with particular age, sex, or other person characteristics at greater risk than other groups with different person characteristics? 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. 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. The strategy of being more inclusive early on is especially useful in investigations that require travel to different hospitals, homes, or other sites to gather information, because collecting extra data while you are there is more efficient than having to return a second time. Subtract the time of onset of the earliest cases from the time of exposure to estimate the minimum incubation period. A good field investigator must be a good manager and collaborator as well as a good epidemiologist, because most investigations are conducted by a team rather than just one individual. In previous similar outbreaks, what have been the sources, modes of transmission, and risk factors for the disease? Nygrd K, Schimmer B, Sbstad , Walde A, Tveit I, Langeland N, Hausken T, Aavitsland P. BMC Public Health. Outbreak: A disease outbreak is the occurrence of cases of disease in excess of what would normally be expected in a defined community, geographical area or season. This also leads to specialization, accuracy, and speed in the workforce. Thus, a line listing contains key information on every case and can be scanned and updated as necessary. Some investigators use a more quantitative approach and calculate a population attributable risk percent for each food. If the epidemic curve points to a narrow period of exposure, what events occurred around that time? For other diseases and conditions, the expected number may be based on locally available data such as hospital discharge records, mortality statistics, or cancer or birth defect registries. PPE stations will be required outside rooms and within areas where affected residents are accommodated. The NZS4304:2002 standard identifies healthcare waste containing pathogens as infectious waste; waste meeting this definition needs to be handled accordingly. In addition, the p-value is exceedingly small, less than 0.001, and far less than the commonly used cutoff of 0.05. Self study modules on Tuberculosis, Module 7: Confidentiality in Tuberculosis Control: Background. Efforts to prevent fecal-oral transmission often focus on rearranging the environment to reduce the risk of contamination in the future and on changing behaviors, such as promoting hand washing. Reusable equipment is to be cleaned and laundered according to required laundry standards. Unfortunately, analytic studies sometimes are unrevealing. A dictionary of epidemiology, 4th ed. Epidemiologic clues to bioterrorism. This association was confirmed in the laboratory, where the outbreak subtype of the Legionnaires disease bacillus was isolated from the water in the mist machines reservoir. : Yes; Hospital Alerted: Yes; Lab Results: WB IgM+; Comments: Erythema migrans; fatigue, sweats, chills; Physician Reporting: Dr. 2. 3. Principles of Management teaches management principles to tomorrow's business leaders by weaving three threads through every chapter: strategy, entrepreneurship and active leadership. 2009 Aug;5(8):e1000471. The social, institutional, and political background associated with outbreaks usually makes their investigation complex and should be taken into account. This is called the risk ratio or the relative risk. 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. J Infect Dis 1992;165:7369. Principles of Outbreak Moreover, the healthcare worker may lose the trust of the patient, which can affect adherence to TB treatment. Depending on the outbreak, occupation, race, or other personal characteristics specific to the disease under investigation and the setting of the outbreak may also be important. All outliers are worth examining carefully because if they are part of the outbreak, they may have an easily identifiable exposure that may point directly to the source. Indeed, the Dictionary of Epidemiology defines outbreak as an epidemic limited to localized increase in the incidence of disease, e.g., village, town, or closed institution.(23). Clipboard, Search History, and several other advanced features are temporarily unavailable. HACCP PRINCIPLES. Clostridium Difficile C. difficile, C diff. Source: Treadwell TA, Koo D, Kuker K, Khan AS. Commonly, the investigator compares the attack rate in the exposed group to the attack rate in the unexposed group to measure the association between the exposure (e.g., the food item) and disease. Emerg Infect Dis 2002;8:398-401. Please enable it to take advantage of the complete set of features! (40) The following table shows the number of case-patients and controls who worked in Building X, near a recently excavated site. The preparations can be grouped into two broad categories: (a) scientific and investigative issues, and (b) management and operational issues. By talking with the laboratory staff you are also informing them about the outbreak, and they can anticipate what type of laboratory resources will be needed. N Engl J Med 2000;343;12237. Investigators enrolled 27 case-patients into a case-control study. Transmission of Norwalk virus during a football game. Staff assigned to cleaning duties should not have access to the kitchen during an outbreak. For librarians and administrators, your personal account also provides access to institutional account management. Yes. As noted above, the epidemic curve shows where you are in the natural course of the epidemic. When is the likely date(s) of exposure, based on one average incubation period prior to the peak (median date) of the outbreak? doi: 10.1371/journal.pcbi.1000471. Define an outbreak .

The timely implementation of effective infection control measures is essential to minimise the incidence of MRSA cases and the magnitude of disease outbreaks. A spot map, like that used by John Snow in London in 1854 (see Lesson 1, Figure 1.1), can give clues about mode of spread. Subtracting 2 weeks from the week of October 28 points to the week of October 14. You must arrange travel, lodging, and local transportation. Oxford University Press is a department of the University of Oxford. In a natural disaster (hurricane or flood), the Federal Emergency Management Agency (FEMA) may be the lead. Thank you for taking the time to confirm your preferences. Here, as in other areas of epidemiology, the observed is compared with the expected.

Start at the earliest case of the epidemic and count back the minimum incubation period, and note this date as well. Create a line listing based on this information. Principles of Communicable Disease Outbreak Management All reports of suspected outbreaks will be investigated immediately. If the duration of exposure is prolonged, the epidemic is called a continuous common-source epidemic, and the epidemic curve has a plateau instead of a peak. Long-term prognosis for clinical West Nile Virus infection. As an example, consider again the outbreak of Legionnaires disease that occurred in Louisiana described at the end of Step 6. This is a common mistake. Because a confidence interval provides more information than a p-value does, many medical and epidemiologic journals now prefer confidence intervals to p-values. The investigators thus began to consider vehicles of transmission to which young adults were commonly exposed. Single rooms with ensuite bathrooms are the preferred choice for managing infectious residents. Philippine Hospital Infection Contol Nurses Associaton (PHICNA) Inc.

Adapted from: Acute hemorrhagic conjunctivitis outbreak caused by Coxsackievirus A24Puerto Rico, 2003. Outbreak Management: The Principles - YouTube Explain the management of an outbreak including control of infection, communication, documentation and reporting processes Explain the. Therefore, to test these hypotheses by using analytic epidemiology (see Step 8), specific or tight case definitions are recommended. Adherence to the principles of strict hand hygiene and the 5 Moments for Hand Hygiene can play a significant role in preventing further cases and reducing environmental contamination. How would you interpret your results? This aggregation of cases seems to be unusual, but frequently the public (and sometimes the health agency) does not know the denominator. Centers for Disease Control and Prevention. Using your epidemic curve and the average and minimum incubation periods for coccidioidomycosis, identify the likely exposure period. Epidemiol Bull 2001;22(4):146. In many other investigations, however, the circumstances are not as straightforward, and information from the series of cases is not sufficiently compelling or convincing. Often, the number of case-patients that can be enrolled in a study is limited by the size of the outbreak. Principles of infectious disease control: overview Infectious diseases remain a leading cause of morbidity, disability, and mortality worldwide. Modern Translation: Figure out what you're employees are good at, and assign them tasks that play to their strengths. Source: Jernigan DB, Raghunathan PL, Bell BP, Brechner R, Bresnitz EA, Butler JC, et al. Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. 2005 Dec;67(12):840-4. doi: 10.1055/s-2005-858896. In 1989, a worldwide epidemic of a previously unrecognized syndrome occurred. First, consider what you know about the disease itself: What is the agents usual reservoir? Federal government websites often end in .gov or .mil. All staff should be educated with regards to what PPE is and how it is used, and donning and doffing processes. Whatever the criteria, they must be applied consistently to all persons under investigation. List the six steps in an outbreak investigation. an outbreak control team 11 2.2.3 Membership of the OCT 11 2.2.4 OCT meetings 12 2.2.5 Resources for the OCT 12 2.2.6 OCT up-scaling 13 3.1 Overview 14 3.2 Principles of Outbreak Management 14 3.3 Outbreak Management 15 1. A large community outbreak of waterborne giardiasis-delayed detection in a non-endemic urban area. The site is secure. Then calculate a chi-square or other statistical test. Readers must therefore always check the product information and clinical procedures with the most up to date published product information and data sheets The attack rate is low among those not exposed, so the difference or ratio between attack rates is high. Peterson LR, Marshall SL, Barton-Dickson C, Hajjeh RA, Lindsley MD, Warnock DW, et al. Nonetheless, many investigators attempt to enroll such population-based controls through dialing of random telephone numbers in the community or through a household survey. The population attributable risk percent may actually be an underestimate in many outbreaks, since it does not take into account such common occurrences as cross-contamination of foods or sampling of a spouses dish. Reporting may rise because of changes in local reporting procedures, changes in the case definition, increased interest because of local or national awareness, or improvements in diagnostic procedures. A detailed description of statistical testing is beyond the scope of this lesson, but the following text presents some key features and formulas. This site needs JavaScript to work properly. Assessment of an outbreak by place not only provides information on the geographic extent of a problem, but may also demonstrate clusters or patterns that provide important etiologic clues. Describe different methods of outbreak management as they pertain to the epidemiological triad (i.e., host, agent and environment). Table 6.8 Risk of Gastroenteritis By Consumption of Beef Virginia, December 2003, Proportion of cases exposed = 53 57 = 93.0% Population attributable risk percent = (49.1 11.4) 49.1 = 76.7%. 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. These data would seem to indicate that persons exposed to Grocery Store A had 11.6 times the odds of developing legionellosis than persons not exposed to that store. The plan should include how often and when to have conference calls with involved agencies, who will be the designated spokesperson, who will prepare health alerts and press releases, and the like. 1995-2022, Containment and cleaning of blood/body substance spill, Safe disposal of clinical/contaminated waste, Safe transportation and handling of laboratory specimens, B1 Appendix A PPE Checklist for Standard Precautions Procedures, B1 Appendix B Aseptic technique for wound care, Introduction to transmission-based precautions (isolation precautions), Points to be considered when isolating a resident, Procedure for setting up and management of an isolation room, Decontamination of isolation room following discharge or death. Descriptive epidemiology describes the where and whom of the disease, allowing you to begin intervention and prevention measures. Do they know anyone else with the disease? An example of the line listing from the 2001 anthrax investigation is shown in Table 6.5. Review the six case report forms in Figure 6.1. When designing a case-control study, you must consider a variety of other issues about controls, including how many to use. Adapted from: Foodborne transmission of hepatitis A Massachusetts, 2001. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment.
