A spot map is a simple and useful technique for illustrating where cases live, work, or may have been exposed. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. 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. Use a camera to photograph working or environmental conditions. Coordinate with the laboratory, and bring back physical evidence to be analyzed. While controls from these groups may be more likely to participate in the study than randomly identified population-based controls, they may not be as representative of the population. Looks like youve clipped this slide to already. Case-patients did, controls did not.(37). response to an enhanced normal disease management process while being prepared for a significant outbreak. Reusable equipment is to be cleaned and laundered according to required laundry standards. Usually, the cases are presumed to have a common cause or to be related to one another in some way. To identify the likely period of exposure from an epidemic curve of an apparent point source epidemic: Ideally, the two dates will be similar, and represent the probable period of exposure. Separate staff should be allocated to affected or non-affected residents where possible. Alternatively, a case may be permanently classified as probable or possible if the patients physician decided not to order the confirmatory laboratory test because the test is expensive, difficult to obtain, or unnecessary. Early recognition of unusual clusters . Knowing the likely period of exposure allows you to ask questions about the appropriate period of time so you can identify the source of the epidemic. NY, New York; FL, Florida; NJ, New Jersey; PA, Pennsylvania; VA, Virginia; DC, District of Columbia; MD, Maryland; CT, Connecticut; F, female; M, male; W, white; B, black; A, Asian; W,H, white with Hispanic ethnicity; NY, New York; NBC, National Broadcasting Company; AMI, American Media Inc.; USPS, United States Postal Service; CBS, Columbia Broadcasting System; PCR, polymerase chain reaction; IHC, immunohistochemical staining; + positive; IgG, immunoglobulin G. Case status and anthrax presentation are described in the anthrax surveillance case definition in the Methods section. A case definition includes clinical criteria and particularly in the setting of an outbreak investigation restrictions by time, place, and person. They may be able to answer some critical questions: What were their exposures before becoming ill? 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. In that situation, it may be useful to draw several epidemic curves with different units on the x-axis to find one that best portrays the data. Epub 2017 Dec 21. When designing a case-control study, you must consider a variety of other issues about controls, including how many to use. For example, in the treatment of tuberculosis (TB), the relationship between the patient and the healthcare worker is extremely important because of the serious consequences of treatment failure. Are they occurring throughout the area, indicating that the interventions are generally ineffective, or are they occurring only in pockets, indicating that the interventions may be effective but that some areas were missed? Only kitchen/catering staff can enter the kitchen area and these staff members should not be accessing outbreak rooms/areas. The illness was given the name eosinophilia-myalgia syndrome. Sometimes, health agencies respond to small numbers of cases, or even a single case of disease, that may not exceed the expected or usual number of cases. Source: Pan American Health Organization. The investigation of an outbreak from an animal source may include state and federal departments of agriculture and/or the Food and Drug Administration (FDA). In case you need help on any kind of academic writing visit website www.HelpWriting.net and place your order, Do not sell or share my personal information, 1. and transmitted securely. HHS Vulnerability Disclosure, Help We've encountered a problem, please try again. Did this person ever go to Luverne? Person characteristics that are usually described include both host characteristics (age, race, sex, and medical status) and possible exposures (occupation, leisure activities, and use of medications, tobacco, and drugs). Occasionally, you may be asked to draw an epidemic curve when you dont know either the disease or its incubation time. Jacobus CH, Holick MF, Shao Q, Chen TC, Holm IA, Kolodny JM, et al. Outbreak investigation is an essential function of public health professionals. )epidemiological investigation doc. Once control and prevention measures have been implemented, they must continue to be monitored. The 95% confidence interval ranged from 2.3 to 78.7. Description: Name: Michael, S; Age: 53; Phone: 555-4899; Address: 48 Valley Hill Dr., Brookville, VA; County: Columbia; Sex: Male; Race: Black; Disease: Lyme Disease; Date of Onset: 9/02/2006; Lab Confirmed? This will vary depending on the disease, for example, in an Ebola outbreak all possible efforts are made to test all suspected cases. Education, child protection, commerce, transportation, and human rights have all suffered. This aggregation of cases seems to be unusual, but frequently the public (and sometimes the health agency) does not know the denominator. Description: Name; Rollins, W; Age: 45; Phone: 555-4771; Address: 127 Midland St.; Portland, VA; County: Columbia; Sex: Male; Race: White; Disease: Lyme Disease; Date of Onset: Mid May 2006; Lab Confirmed? Whichever decision you make, you may be right or you may be wrong. For example, during an investigation of an outbreak of Legionnaires disease in Louisiana, members of the investigative team discussed what they knew based on the descriptive epidemiology. Start at the earliest case of the epidemic and count back the minimum incubation period, and note this date as well. Surveillance takes place prior to, during and after outbreaks. The most common statistical test for data in a two-by-two table from an outbreak is the chi-square test. : 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. - 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 Temporal variability and social heterogeneity in disease transmission: the case of SARS in Hong Kong. Beef, which had the highest attack rate among those who ate it, the lowest attack rate among those who did not eat it, and could account for almost all (53 of 57) of the cases, was indeed the culprit. Cleaning schedules should incorporate the frequent cleaning of frequently touched environmental surfaces such as door handles, taps, handrails, technical aids, buzzers and other switches and devices. You also need to know what supplies or equipment to bring to protect yourself. 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. Verify diagnosis 4. The numbering scheme for this step is problematic, because preparing for field work often is not the first step. Case finding and line listing 6. 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). Case definitions: meningococcal disease and viral meningitis. In addition, conversations with patients are very useful in generating hypotheses about disease etiology and spread. Table 6.3 Line Listing of 7 Persons with Suspected Eosinophilia-myalgia, * Severe enough to affect the patients ability to pursue usual daily activities, Eventually, public health officials agreed on the following revised case definition:(26). Description: The number of exposed cases times the number of unexposed controls divided by the number of exposed controls times the number of unexposed cases. All waste types should always be handled with the use of appropriate PPE. Palmer SR. N Engl J Med 1977;297:118997.

An outbreak management checklist which could be used by OMTs or ICPs can be found in appendix 4. The following are the 14 management principles: 1. Public Health Principles . J Epidemiol Comm Health 1989;43:3114. Transmission of Norwalk virus during a football game. The steps listed in Table 6.2 are presented in conceptual order; in practice, however, several steps may be done at the same time, or the circumstances of the outbreak may dictate that a different order be followed. Identification of an outbreak To be able to perform the outbreak management process 1.

An epidemic curve that has a steep upslope and a more gradual down slope (a so-called log-normal curve) is characteristic of a point-source epidemic in which persons are exposed to the same source over a relative brief period. Figure 6.2c Outbreak of SalmonellaEnteritidis Gastroenteritis Maryland, 2003 (Epidemic Curve by One Day Intervals), Figure 6.2d Outbreak of SalmonellaEnteritidis Gastroenteritis Maryland, 2003 (Epidemic Curve by 6-Hour Intervals). 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 Interpreting an epidemic curve. Single case of disease caused by an uncommon agent (e.g., glanders, smallpox, viral hemorrhagic fever, inhalational or cutaneous anthrax) without adequate epidemiologic explanation, Unusual, atypical, genetically engineered, or antiquated strain of an agent (or antibiotic-resistance pattern), Higher morbidity and mortality in association with a common disease or syndrome or failure of such patients to respond to usual therapy, Unusual disease presentation (e.g., inhalational anthrax or pneumonic plague), Disease with an unusual geographic or seasonal distribution (e.g., tularemia in a non-endemic area, influenza in the summer), Stable endemic disease with an unexplained increase in incidence (e.g., tularemia, plague), Atypical disease transmission through aerosols, food, or water, in a mode suggesting deliberate sabotage (i.e., no other physical explanation), No illness in persons who are not exposed to common ventilation systems (have separate closed ventilation systems) when illness is seen in persons in close proximity who have a common ventilation system, Several unusual or unexplained diseases coexisting in the same patient without any other explanation, Unusual illness that affects a large, disparate population (e.g., respiratory disease in a large population may suggest exposure to an inhalational pathogen or chemical agent), Illness that is unusual (or atypical) for a given population or age group (e.g., outbreak of measles-like rash in adults), Unusual pattern of death or illness among animals (which may be unexplained or attributed to an agent of bioterrorism) that precedes or accompanies illness or death in humans, Unusual pattern of death or illness among humans (which may be unexplained or attributed to an agent of bioterrorism) that precedes or accompanies illness or death in animals, Ill persons who seek treatment at about the same time (point source with compressed epidemic curve), Similar genetic type among agents isolated from temporally or spatially distinct sources, Simultaneous clusters of similar illness in noncontiguous areas, domestic or foreign, Large number of cases of unexplained diseases or deaths. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more. Investigators enrolled 27 case-patients into a case-control study. For example, the epidemic curves shown in Figures 6.2b and 6.2c display the same data as in Figure 6.2a; the x-axis is measured in units of 12 hours in Figure 6.2a, 6 hours in Figure 6.2b, and 24 hours (1 day) in 6.2c. Therefore, to test these hypotheses by using analytic epidemiology (see Step 8), specific or tight case definitions are recommended. When is the likely dates of exposure, based on the minimum incubation period before the first case? Typically, hypotheses in a field investigation are evaluated using a combination of environmental evidence, laboratory science, and epidemiology. Who is in charge? They help us to know which pages are the most and least popular and see how visitors move around the site. (31) For example, clustering of cases in a wing of a nursing home is consistent with either a focal source or person-to-person spread, whereas scattering of cases throughout the facility is more consistent with a widely disseminated vehicle or a source common to the residents that is not associated with room assignment, such as a common dining hall or water supply. In previous similar outbreaks, what have been the sources, modes of transmission, and risk factors for the disease? Centers for Disease Control and Prevention. Malimu principles of outbreak investigation, (E pi !! Consider again the gastroenteritis data in Table 6.8. Just as case-patients may have important insights into causes, so too may the local health department staff. Vaccinations promote development of specific antibodies that protect against infection. You should also take care of personal matters before you leave, especially if the investigation is likely to be lengthy. Renault (Claude Rains) to his policemen after Rick Blaine (Humphrey Bogart) had just shot a Nazi officer, Casablanca, 1942. Principles of outbreak investigation 1. 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. Several counties are shaded to indicate the number of cases in that location. The curve shows where you are in the course of the epidemic still on the upswing, on the down slope, or after the epidemic has ended. Figure 6.2b Outbreak of SalmonellaEnteritidis Gastroenteritis Maryland, 2003 (Epidemic Curve by 6-Hour Intervals). As noted in Step 1, development of a communications plan and communicating with those who need to know during the investigation is critical. Table 6.7 includes data from an investigation of an outbreak of Salmonella Typhimurium gastroenteritis following a companys holiday banquet in December 2003. The 95% confidence interval for the risk ratio of 5.7 ranged from 2.2 to 14.6. By comparing the observed with expected patterns, epidemiologists can determine whether the observed pattern differs substantially from what should be expected and, if so, by what degree. A questionnaire could be distributed to determine the true occurrence of clinical symptoms, or laboratory specimens could be collected to determine the number of asymptomatic cases. Only one case was identified in Sioux Falls, South Dakota, 60 miles away. Public health workers must therefore look for additional cases to determine the true geographic extent of the problem and the populations affected by it. As noted above, the epidemic curve shows where you are in the natural course of the epidemic. Half of the students traveled from December 2 to December 7 (Tour A); the other half traveled from December 3 to December 8 (Tour B). In an outbreak context, hypotheses are generated in a variety of ways. Traditionally, the information described above is collected on a standard case report form, questionnaire, or data abstraction form. The primary objective in outbreak management is to protect public health by identifying the source and implementing control measures to prevent further spread or recurrence of the infection. Access to content on Oxford Academic is often provided through institutional subscriptions and purchases. To interrupt vector borne transmission, measures may be directed toward controlling the vector population, such as spraying to reduce the mosquito population that may carry West Nile virus. Atlanta: CDC; [updated 1999 Oct; cited 2006 Sep 19]. PPE should be included in the outbreak kit (see Section B4.11). Following successful sign in, you will be returned to Oxford Academic. Using the epidemiologic data, the investigators were able to implicate the ultrasonic mist machine that sprayed the fruits and vegetables. Becker KM, Moe CL, Southwick KL, MacCormack JN. Outbreak investigation is an essential function of public health professionals. See below. The outbreak of West Nile virus infection in the New York City area in 1999. Coccidioidomycosis among workers at an archaeologic site, northeast Utah. Epidemiologic clues to bioterrorism. This assumption is known as the null hypothesis. doi: 10.1371/journal.pcbi.1000471. 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. In most outbreak investigations, the primary goal is control of the outbreak and prevention of additional cases. In response, health departments have made great strides in attempting to keep the public informed. Through Epi-X, CDC officials, state and local health departments, poison control centers, and other public health professionals can access and share preliminary health surveillance information quickly and securely. In summary, the graph reflects an outbreak (number of cases clearly in excess of usual) beginning during the week of October 28, peaking during the week of November 4, and ending during the week of November 18. Snow on cholera. 1. Readers must therefore always . Consider the gastroenteritis and beef consumption data presented in Table 6.8. A p-value this small indicates that the null hypothesis is highly improbable, and the investigators rejected the null hypothesis. Nygrd K, Schimmer B, Sbstad , Walde A, Tveit I, Langeland N, Hausken T, Aavitsland P. BMC Public Health. Investigation of bioterrorism-related anthrax, United States, 2001: epidemiologic findings. Principles of Outbreak invEstigation. The severity of epidemic depends on - 1. A retrospective cohort study is the study of choice for an outbreak in a small, well-defined population, such as an outbreak of gastroenteritis among wedding guests for which a complete list of guests is available. A large community outbreak of waterborne giardiasis-delayed detection in a non-endemic urban area. Our books are available by subscription or purchase to libraries and institutions. ). The incubation period for hepatitis A ranges from 15 to 50 days (roughly 2 to 7 weeks), with an average incubation period of 2830 days (roughly one month). If so, where are the new cases? Capt. 1996 Nov 20;116(28):3329-34. Principles of Communicable Disease Outbreak Management All reports of suspected outbreaks will be investigated immediately. Whether an apparent problem should be investigated further is not strictly tied to verifying the existence of an epidemic (more cases than expected). The relative risk is 5.7, which most epidemiologists would deem a strong association between exposure and disease. Wien Klin Wochenschr. What is the appropriate measure of association? For example, contaminated foods should be discarded, and surgical equipment is routinely sterilized to prevent transmission. You indicated this topic was not helpful to you Could you please leave a comment telling us why? Cori A, Bolle PY, Thomas G, Leung GM, Valleron AJ. Infection Prevention & Control. In an attachment, you found an official laboratory report from the Upper Northern . provided by the manufacturers and the most recent codes of conduct and safety regulations. Principles of Outbreak Management Surveillance and Assessment Conduct ongoing surveillance and monitoring for unusual clusters of illness in patients/residents and HCW, and identification of possible outbreaks. 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. 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. When on the society site, please use the credentials provided by that society. 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. What vehicles are commonly implicated? The controls provide the level of exposure you would expect to find among the case-patients if the null hypothesis were true. 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. A large community outbreak of salmonellosis caused by intentional contamination of restaurant salad bars.
