), mode of transmission (Vector? Risk Factors and Transmission are both epidemiological determinants. 1. The challenge … 2020 Feb 20;6(1):13. doi: 10.1038/s41572-020-0147-3. This issue of The Journal of Infectious Diseases contains 2 articles focusing on different aspects of Zika virus (ZIKV) transmission and control. Multidrug-resistant tuberculosis cases were identified as single case events and therefore did not meet our inclusion criteria in this study. Foodborne and waterborne IDTEs were the most frequently occurring events (n = 48), followed by vectorborne and rodentborne IDTEs (n = 27), airborne IDTEs (n = 10) vaccine preventable IDTEs (n = 10), other zoonotic IDTEs (n = 7), injection drug use–associated IDTEs (n = 4), influenza IDTEs (n = 4), healthcare-associated IDTEs (n = 3), multidrug resistance–associated IDTEs (n = 2), and sexually transmitted IDTE (n = 1). Large ongoing Q fever outbreak in the south of the Netherlands, 2008. 4. Isolation of a novel coronavirus from a man with pneumonia in Saudi Arabia. Epidemiologic role of infectious agents in the development of disease states 7. More specifically, travel and tourism, food and water quality, natural environment, global trade, and climate were the top 5 drivers of all IDTEs identified through epidemic intelligence at ECDC. Cluster dendrogram from hierarchical cluster analysis of drivers contributing to observed infectious disease threat events (IDTEs), Europe, 2008–2013. Of 7 malaria threat events, 5 included autochthonous cases (in Spain, Greece, and Belgium). The 2007–2010 Q fever epidemic in the Netherlands: characteristics of notified acute Q fever patients and the association with dairy goat farming. Hierarchical cluster analysis of all drivers identified travel and tourism as a distinctly separate driver. (See the Major Article by Bartsch et al, on pages 920–31; Rosenberg et al, on pages 932–40.). -generally extrinsic determinants of disease occurrence-can be physical (climate, shelter, soil, and geography) or biological (man, vector, plants, and free-living animals) Climate. SEP has been previously established as a potential determinant of infectious diseases in general. The physical signs and symptoms of cholera aren't caused by the bacterium itself, but rather a toxin it produces once it's inside the body. With the increased mobility of human populations, diseases can quickly spread around the world. However, more important, the likelihood of IDTEs originating in the first place can be reduced by intervening directly on their underlying drivers. Four of these IDTEs consisted of the first autochthonous WNV cases in 4 different European countries and 1 large outbreak in southeastern Europe with >260 cases (16). Nearly half of the 27 IDTEs within the vectorborne and rodentborne IDTE category were caused by West Nile virus (WNV) infections. A 2008 study, which was conducted by the European Centre for Disease Prevention and Control (ECDC) and based on expert consultation and literature review, projecting how the risk of emerging infectious diseases in Europe will be shaped in the future determined that drivers can be categorized into 3 main groups: globalization and environment, sociodemographic, and public health systems (Table 1) (7). Only 1 sexually transmitted IDTE was identified by epidemic intelligence. There was no evidence of an increased risk of infectious disease transmission in the host population in Europe during the 2015 influx of migrants or asylum seekers; however, ECDC advocated for the implementation of basic public health measures, health assessments, and vaccination to address the health needs of migrants (25). Theory that disease was transmitted by a cloud. Once you have found a specific outbreak, you can discuss the epidemiological determinants of thisoutbreak more fully. Climate change projections of West Nile virus infections in Europe: implications for blood safety practices. Q fever, psittacosis, and diseases caused by cowpox virus and E. coli (with an unusual transmission pathway, e.g., contaminated farm soil and petting of contaminated animals) were included in the other zoonoses IDTE category. Hypotheses about the determinants of disease arise from considering the characteristics of person, place, and time and looking for differences, similarities, and correlations. Proper maintenance of the physical infrastructure can prevent these IDTEs. a.

Center for Social Epidemiology and Population Health. Determinants of Disease 3. 2. Additional information is gathered through direct contact with epidemiologists and health authorities in the EU and abroad. Crowded and poorly ventilated living and working environments often associated with poverty constitute direct risk factors for tuberculosis transmission. (See the Major Article by Bartsch et al, on pages 920–31; Rosenberg et al, on pages 932–40.). Forecast and control of epidemics in a globalized world. Saving Lives, Protecting People, European Centre for Disease Prevention and Control, Stockholm, Sweden (J.C. Semenza, L. Balkanyi, L. Espinosa, P. Penttinen), Stockholm University Stockholm Resilience Centre, Stockholm (E. Lindgren, M.S. Infectious disease threat events (IDTEs) are increasing in frequency worldwide. Food and water quality was the second most frequent driver of IDTEs in Europe. In the face of an outbreak of pandemic influenza, it is important to understand factors that influence how people behave in order to decrease the likelihood of infection, transmission, and disease severity. 1858: Scarlet fever also came in waves. Cholera is caused by the bacterium Vibrio cholerae, a tiny microbe that can infect the intestines. The calculation of the distance between 2 drivers was derived from the multidimensional driver space, based on whether the drivers were present (1) or absent (0) during the emergence of an IDTE. Discuss how an outbreak would have affected your community at a systems level (i.e., the functioning of schools, local government, businesses, hospitals) if an outbreak had occurred in your community. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. a. Epidemic intelligence is heavily influenced by media coverage, geographic focus, length of the epidemic intelligence monitoring cycle, diagnostic procedures, and sensitivity of surveillance systems, among many other factors. A ranking of the relative importance of these drivers can help prioritize risk-based surveillance to anticipate disease emergence and spread (8,9). A conceptual framework for the determinants of outbreak detection through automated surveillance , , , . doi: 10.1371/journal.pone.0179356. ), virulence (how deadly is it? Many of the fundamental and basic determinants of emerging infectious diseases have persisted over time, but dynamic global trends provide more opportunities for emerging infectious diseases to occur and expand swiftly (5,6). WNV infection and malaria are notifiable diseases in the EU and, thus, subject to indicator surveillance; however, special threat events are picked up by event-based surveillance as well. Due to persistence of C. burnetii in the environment, continued surveillance for Q fever is warranted. The aim of this CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. A large outbreak of hantavirus infections in Germany in 2010 was attributed to bank vole (Clethrionomys glareolus) populations, which had increased substantially due to excessive seed production the previous year (19); human behavior (e.g., outdoor activities in summer); dust contaminated with rodent excreta following dry and warm weather; and heightened awareness, with better diagnosis and reporting. Keywords: Ebola virus infection; chain of infection; determinants; replication number; risk factor; source; spread; transmission. Given the clear and present danger of newly emerging infectious disease outbreaks in the near future and the importance of the public response and precautionary actions to control the spread, additional research on risk perceptions and other behavioural determinants is warranted. We conducted this study to identify, differentiate, and rank drivers of observed IDTEs in Europe detected through ECDC epidemic intelligence activities. Serious games provide an underutilized tool to promote learning and innovation around global health crises. 8 Human outbreaks are typically started when an individual has come into contact with the blood of an infected mammal or bushmeat6 although the West African outbreak is thought to have begun because of fruit bat exposure. International travel from areas with epidemic and endemic diseases has resulted in continuous importation of infected persons into Europe who can, for example, trigger outbreaks of airborne diseases. General introduction into the Ebola virus biology and disease. Persons, services, goods, capital, and microbes are free to move across borders of the European Union (EU), which currently has 28 member states and an estimated population of 508.2 million. This is the first ever practical guide to the valuable role that health promotion can play in disease outbreaks and health emergencies. Among these, travel and tourism proved to be significantly distinct in the hierarchical cluster analysis and cluster dendrogram (Figure 3). herd immunity. We analyzed underlying drivers of 116 IDTEs detected in Europe during 2008–2013 by epidemic intelligence at the European Centre of Disease Prevention and Control. Figure 2. The following persons have contributed to the epidemic intelligence activities at the European Centre for Disease Prevention and Control: Sergio Brusin, Alastair Donachie, Assimoula Economopoulou, Alice Friaux, Kaja Kaasik Aaslav, Peter Kreidl, Jas Mantero, Thomas Mollet, Otilia Sfetcu, Bertrand Sudre, and Edit Szegedi. It must be an outbreak that has crossed international borders. Epidemiologists assume that illness does not occur randomly in a population, but happens only when the right accumulation of risk factors or determinants exists in an individual. Social Determinants of EBV Outbreak in West Africa The population health is determined by the outcome of the interplay between the population and social environment. Clipboard, Search History, and several other advanced features are temporarily unavailable. These characteristics are carefully considered when a disease outbreak occurs, because they provide important clues regarding the source of the outbreak. Seventeen drivers were identified and categorized into 3 groups: globalization and environment, sociodemographic, and public health systems. We analyzed underlying drivers of 116 IDTEs detected in Europe during 2008–2013 by epidemic intelligence at the European Centre of Disease Prevention and Control. You are asked to choose ONE of the following communicable diseases to … This site needs JavaScript to work properly. Contrasting academic and lay press print coverage of the 2013-2016 Ebola Virus Disease outbreak. Unfortunately, most of the outbreaks were left without investigation. Based on PMT, this study investigated the determinants of poultry farmers’ HPAI outbreak information sources, risk perception of poultry infected with HPAI and reported adoption of BBs. Ebola virus infection; chain of infection; determinants; replication number; risk factor; source; spread; transmission. Health Promotion in Disease Outbreaks and Health Emergencies. We then used a set of dissimilarities for the distances between drivers to perform a hierarchical cluster analysis (11). Please use the form below to submit correspondence to the authors or contact them at the following address: Jan C. Semenza, European Centre for Disease Prevention and Control, Tomtebodavägen 11A, SE-171 83 Stockholm, Sweden. While this has led to a growing body of research studying the effects of a variety of international and domestic factors on disease outbreaks, very little research has inverted this relationship by studying the effects of disease outbreaks on international systems. That toxin disrupts the way cells absorb and process fluids and electrolytes, forcing them to go in just one direction: out. The current Ebola outbreak is a dramatic example of how policy and social determinants of health intersect to impact population health worldwide. Restricting international travel in a globalized world to reduce the likelihood of IDTEs is both unrealistic and undesirable; however, monitoring and modeling air traffic patterns for pathogen importation risk can potentially accelerate early case detection and rapid response and effective control of IDTEs (36). ( NewMediaWire) - December 03, 2020 - DALLAS - Researchers from University of Michigan and University of Alabama studying the impact of in-person college classes on community COVID-19 cases and the affect social determinants of health play in virus outbreaks and deaths won the top awards in the American Heart Association’s first ever COVID-19 data challenge. Aerosol? Although the 3 groups are somewhat artificial and not entirely mutually exclusive, they can serve as a framework for the interpretation of infectious disease threat events (IDTEs) in Europe. MATERIALS AND METHODS: We used an existing software platform to simulate waterborne disease outbreaks of varying duration and magnitude. Although observed modes of transmission mainly include direct contact and contaminated staff, high case fatality ratio and frequent contacts among individuals in developed countries are among determinants which may lead to the development of the EVD outbreak. 3. Poverty is a powerful determinant of tuberculosis. Background In 2007, physicians on Yap Island reported an outbreak of illness characterized by rash, conjunctivitis, and arthralgia. After a devastating 7.0 magnitude earthquake in January 2010, CDC’s support expanded to address Haiti’s critical health needs, such as cholera, as … This outbreak was not unexpected, given the highly infectious nature of measles paired with the Somali community’s steadily decreasing MMR vaccination rates in young children. The IDTE drivers were organized into 3 categories: globalization and environment, sociodemographic, and public health systems (Table 1) (7). Describe the outbreak of the disease selected in part A, including each of the following: • name of the disease • the countries involved • the date the outbreak was discovered • the dates the disease reached each involved country. Analyze the epidemiological determinants of the outbreak. Water distribution system and diarrheal disease transmission: a case study in Uzbekistan. In addition, changes in vaccination practices have indicated an increase in communicable diseases that were once thought to be under control. Global trends in emerging infectious diseases. Economic optimization of a global strategy to address the pandemic threat. attack rate. In 2008, for the first time in 14 years, measles was declared endemic in the UK, meaning that the disease was sustained within the population. Table of Contents – Volume 22, Number 4—April 2016. Information about the underlying drivers of these IDTEs was extracted from several sources: the Communicable Disease Threats Report (a weekly bulletin generated by the epidemic intelligence team at ECDC), epidemiologic reports and communications, rapid risk assessments, threat assessments, mission reports, and associated peer-reviewed publications retrieved from PubMed. The risk of importing Y. pestis to nonendemic regions may have increased over recent years. Epidemic profile of Shiga-toxin–producing. The evolution of Ebola virus disease outbreaks. - Exposure followed by "waves" of secondary and tertiary cases. It must be an outbreak that has crossed international borders. Author Summary In 2012, Europe saw its first dengue epidemic taking place on the Atlantic island of Madeira. Analyze the epidemiological determinants and risk factors associated with the outbreak. The drivers for the influenza IDTE group of both seasonal and pandemic influenza were travel and tourism, vulnerable groups, social and demographic, and surveillance and reporting. The arrows indicate the flow of information in the surveillance process. Students will learn about modern outbreaks, historic outbreaks of significance and will explore the tools that outbreak investigators use to stop the spread of outbreaks in populations and to prevent future outbreaks. What is this type of curve seen with? Contact? Measles outbreak in Bulgaria: poor maternal educational attainment as a risk factor for medical complications. Discuss the risk factors involved. Although observed modes of transmission mainly include direct contact and contaminated staff, high case fatality ratio and frequent contacts among individuals in developed countries are among determinants which may lead to the development of the EVD outbreak. USA.gov. EPI 201 Outbreak Investigation and Response (5) I&S/NW, QSR J. BASEMAN Provides an introduction to infectious disease outbreaks of both domestic and global significance. Scarlet fever is a bacterial infection that can occur after … how it will affect the functioning of schools local government businesses hospitals). We thank James Mendlein, Mike Catchpole, Mark Miller, and 3 anonymous reviewers for critical feedback on the manuscript. Euclidian distances (based on how the IDTE types occurred with the driver category in the empirical data) were also calculated between each 1 driver pair (11).
