Medical planning for mass gathering sports events in brazil / Planificación médica para eventos deportivos masivos en brasil / Planejamento médico para eventos esportivos de massa no brasil

ABSTRACT Introduction: Medical planning for mass gathering events is founded on the structuring of assistance to the population involved and the preservation of the response capacities of the local healthcare system. Large sporting events attended by crowds are increasingly common in society. These events have been shown to be dangerous, generating higher incidences of injuries and illnesses than usual. Thus, planning and the interaction among various public and private sectors are required for the prevention of and response to emergencies and incidents involving multiple victims. Methods: Recently published studies on medical planning for large sports events and current federal agency legislation were selected to conduct an updated review on the subject. Results: After reading titles and abstracts, 159 papers were chosen for a full reading, 50 of which met the eligibility criteria and were included as the basis for this review. The size of the audience, the weather, and the behavior of the crowd seem to contribute significantly to the estimated need for resources in sporting events. Conclusion: Mass events require planning for prevention and to strengthen the resilience of host communities. There is a still a lack of evidence that these events increase the risk of the mass spreading of disease. Level of Evidence: V; Expert opinion .

Impact of patron saint festivities on cholera in three communes in Haiti.

BACKGROUND: Religious pilgrimages are among the anthropogenic factors known to be associated with the transmission of diarrheal diseases, such as cholera. This ecological study aimed to describe the evolution of cholera and assess the relationship between the implementation of the 'coup de poing' strategy during the patron saint festivities and the incidence of cholera in the three communes of Cabaret, Carrefour, and Croix-des-Bouquets in Haiti in 2017. METHODS: An epidemiological curve was produced to illustrate the evolution of cholera at the communal level. Generalized linear models assuming a Poisson distribution were used to weight the annual cholera incidence of communal sections against variables such as the number of patronal festivities, population density and annual precipitation rates. The number of cases in the week of the festivity as well as one and 2 weeks later was weighted against patronal festivities and weekly precipitation rates. RESULTS: In total, 3633 suspected cholera cases were continuously reported in three communes in Haiti (Cabaret, Carrefour, Croix-des-bouquets) during the 52-epidemiological week period in 2017. After controlling for rainfall and population density, the implementation of the 'coup de poing' strategy during the patron saint festivities was associated with a significant reduction in cholera incidence of 57.23% [PR = 0.4277 (97.5% CI: 0.2798-0.6193), p = 0.0000244]. The implementation of the strategy was associated with a reduction in cholera incidence of 25.41% 1 week following patronal festivities. CONCLUSION: This study showed a continuous presence of cholera in three communes in Haiti in 2017 and an association between the implementation of the 'coup de poing' strategy during patronal festivities and a reduction in cholera incidence. The findings imply that the multi-partner 'coup de poing' strategy may have contributed to the reduced cholera incidence following patron saint festivities and in Ouest department in Haiti in 2017.

COVID-19 - the role of mass gatherings.

Mass gathering (MG) medicine emerged against the backdrop of the 2009 pandemic H1N1 Public Health Emergency of International Concern (PHEIC) when the Kingdom of Saudi Arabia (KSA) hosted the largest annual mass gathering of over 3 million pilgrims from 180 plus countries. However, the events surrounding the latest threat to global health, the PHEIC COVID-19, may be sufficient to highlight the role of mass gatherings, mass migration, and other forms of dense gatherings of people on the emergence, sustenance, and transmission of novel pathogens. The COVID-19 spread illustrates the role of MGs in exacerbation of the scope of pandemics. Cancellation or suspension of MGs would be critical to pandemic mitigation. It is unlikely that medical countermeasures are available during the early phase of pandemics. Therefore, mitigation of its impact, rather than containment and control becomes a priority during pandemics. As the most systematically studied MG-related respiratory disease data come from KSA, the cancellation of Umrah by the KSA authorities, prior to emergence of cases, provide the best opportunity to develop mathematical models to quantify event cancellations related mitigation of COVID-19 transmission in KSA and to the home countries of pilgrims. COVID-19 has already provided examples of both clearly planned event cancellations such as the Umrah suspension in KSA, and where outbreaks and events were continued.

Mass Gatherings and Diarrheal Disease Transmission Among Rural Communities in Coastal Ecuador.

Mass gatherings exacerbate infectious disease risks by creating crowded, high-contact conditions and straining the capacity of local infrastructure. While mass gatherings have been extensively studied in the context of epidemic disease transmission, the role of gatherings in incidence of high-burden, endemic infections has not been previously studied. Here, we examine diarrheal incidence among 17 communities in Esmeraldas, Ecuador, in relation to recurrent gatherings characterized using ethnographic data collected during and after the epidemiologic surveillance period (2004-2007). Using distributed-lag generalized estimating equations, adjusted for seasonality, trend, and heavy rainfall events, we found significant increases in diarrhea risk in host villages, peaking 2 weeks after an event's conclusion (incidence rate ratio, 1.21; confidence interval, adjusted for false coverage rate of ≤0.05: 1.02, 1.43). Stratified analysis revealed heightened risks associated with events where crowding and travel were most likely (2-week-lag incidence rate ratio, 1.51; confidence interval, adjusted for false coverage rate of ≤0.05: 1.09, 2.10). Our findings suggest that community-scale mass gatherings might play an important role in endemic diarrheal disease transmission and could be an important focus for interventions to improve community health in low-resource settings.

Saúde na Copa: The World's First Application of Participatory Surveillance for a Mass Gathering at FIFA World Cup 2014, Brazil.

BACKGROUND: The 2005 International Health Regulations (IHRs) established parameters for event assessments and notifications that may constitute public health emergencies of international concern. These requirements and parameters opened up space for the use of nonofficial mechanisms (such as websites, blogs, and social networks) and technological improvements of communication that can streamline the detection, monitoring, and response to health problems, and thus reduce damage caused by these problems. Specifically, the revised IHR created space for participatory surveillance to function, in addition to the traditional surveillance mechanisms of detection, monitoring, and response. Participatory surveillance is based on crowdsourcing methods that collect information from society and then return the collective knowledge gained from that information back to society. The spread of digital social networks and wiki-style knowledge platforms has created a very favorable environment for this model of production and social control of information. OBJECTIVE: The aim of this study was to describe the use of a participatory surveillance app, Healthy Cup, for the early detection of acute disease outbreaks during the Fédération Internationale de Football Association (FIFA) World Cup 2014. Our focus was on three specific syndromes (respiratory, diarrheal, and rash) related to six diseases that were considered important in a mass gathering context (influenza, measles, rubella, cholera, acute diarrhea, and dengue fever). METHODS: From May 12 to July 13, 2014, users from anywhere in the world were able to download the Healthy Cup app and record their health condition, reporting whether they were good, very good, ill, or very ill. For users that reported being ill or very ill, a screen with a list of 10 symptoms was displayed. Participatory surveillance allows for the real-time identification of aggregates of symptoms that indicate possible cases of infectious diseases. RESULTS: From May 12 through July 13, 2014, there were 9434 downloads of the Healthy Cup app and 7155 (75.84%) registered users. Among the registered users, 4706 (4706/7155, 65.77%) were active users who posted a total of 47,879 times during the study period. The maximum number of users that signed up in one day occurred on May 30, 2014, the day that the app was officially launched by the Minister of Health during a press conference. During this event, the Minister of Health announced the special government program Health in the World Cup on national television media. On that date, 3633 logins were recorded, which accounted for more than half of all sign-ups across the entire duration of the study (50.78%, 3633/7155). CONCLUSIONS: Participatory surveillance through community engagement is an innovative way to conduct epidemiological surveillance. Compared to traditional epidemiological surveillance, advantages include lower costs of data acquisition, timeliness of information collected and shared, platform scalability, and capacity for integration between the population being served and public health services.

Rapid Spread of Zika Virus in The Americas--Implications for Public Health Preparedness for Mass Gatherings at the 2016 Brazil Olympic Games.

Mass gatherings at major international sporting events put millions of international travelers and local host-country residents at risk of acquiring infectious diseases, including locally endemic infectious diseases. The mosquito-borne Zika virus (ZIKV) has recently aroused global attention due to its rapid spread since its first detection in May 2015 in Brazil to 22 other countries and other territories in the Americas. The ZIKV outbreak in Brazil, has also been associated with a significant rise in the number of babies born with microcephaly and neurological disorders, and has been declared a 'Global Emergency by the World Health Organization. This explosive spread of ZIKV in Brazil poses challenges for public health preparedness and surveillance for the Olympics and Paralympics which are due to be held in Rio De Janeiro in August, 2016. We review the epidemiology and clinical features of the current ZIKV outbreak in Brazil, highlight knowledge gaps, and review the public health implications of the current ZIKV outbreak in the Americas. We highlight the urgent need for a coordinated collaborative response for prevention and spread of infectious diseases with epidemic potential at mass gatherings events.

Illness in travelers returned from Brazil: the GeoSentinel experience and implications for the 2014 FIFA World Cup and the 2016 Summer Olympics.

BACKGROUND: Brazil will host the 2014 FIFA World Cup and the 2016 Olympic and Paralympic Games, events that are expected to attract hundreds of thousands of international travelers. Travelers to Brazil will encounter locally endemic infections as well as mass event-specific risks. METHODS: We describe 1586 ill returned travelers who had visited Brazil and were seen at a GeoSentinel Clinic from July 1997 through May 2013. RESULTS: The most common travel-related illnesses were dermatologic conditions (40%), diarrheal syndromes (25%), and febrile systemic illness (19%). The most common specific dermatologic diagnoses were cutaneous larva migrans, myiasis, and tungiasis. Dengue and malaria, predominantly Plasmodium vivax, were the most frequently identified specific causes of fever and the most common reasons for hospitalization after travel. Dengue fever diagnoses displayed marked seasonality, although cases were seen throughout the year. Among the 28 ill returned travelers with human immunodeficiency virus (HIV) infection, 11 had newly diagnosed asymptomatic infection and 9 had acute symptomatic HIV. CONCLUSIONS: Our analysis primarily identified infectious diseases among travelers to Brazil. Knowledge of illness in travelers returning from Brazil can assist clinicians to advise prospective travelers and guide pretravel preparation, including itinerary-tailored advice, vaccines, and chemoprophylaxis; it can also help to focus posttravel evaluation of ill returned travelers. Travelers planning to attend mass events will encounter other risks that are not captured in our surveillance network.

Cricket worldcup: a stress test for the surveillance system in the Caribbean / La copa mundial de críquet: un test de estrés para el sistema de vigilancia en el Caribe

OBJECTIVE: To describe the development and implementation of, and major findings and recommendations from, a regional mass gathering surveillance system (MGSS) in support of the International Cricket Council Cricket World C up West Indies 2007. METHODS: The regional MGSS was developed by the Caribbean Epidemiology Centre (CAREC) and its member countries as an adaptation of the routine communicable disease surveillance system in order to rapidly detect unusual disease events during the tournament. The implementation of the MGSS required the identification of additional human and financial resources, capacity building activities, laboratory strengthening, and improved global epidemic surveillance and communication mechanisms. RESULTS: Timeliness and completeness of data reporting in the MGSS were both > 85%. No unusual pathogens were identified in the region during the tournament. Only dengue and influenza, both endemic to the region, were identified. The early alert detection software used identified a total of 24 aberrations from seven countries, the largest proportions being gastroenteritis, fever and respiratory symptoms and injuries. All aberrations were promptly investigated and most were found to be false alerts. Three unusual disease events were detected, all from one country. They were responded to in a timely manner and did not adversely affect the tournament. CONCLUSIONS: The surveillance capacities gained in preparing for, and supporting, the tournament assisted in strengthening and testing the already existing national and regional communicable disease surveillance systems. Events such as these should be utilized to strengthen already existing surveillance systems, which should be flexible enough to respond to changing events.

OBJETIVO: Describir el desarrollo e implementación, así como los hallazgos principales y las recomendaciones de un sistema de vigilancia regional de eventos masivos (MGSS), en apoyo al Consejo Internacional de Críquet en la Copa Mundial de Críquet de West Indies 2007. MÉTODOS: El sistema de vigilancia regional de eventos masivos, conocido por sus siglas en inglés MGSS, fue desarrollado por el Centro de Epidemiología del Caribe (CAREC) y sus países miembros, como una adaptación del sistema de vigilancia rutinaria de enfermedades comunicables a fin de detectar rápidamente manifestaciones inusuales de enfermedades durante el torneo. La implementación del MSGS requirió la identificación de recursos humanos y financieros adicionales, actividades de construcción de capacidades, fortalecimiento de los laboratorios, así como el mejoramiento de la vigilancia epidemiológica y los mecanismos de comunicación globales. RESULTADOS: La calidad del reporte de los datos en cuanto a su integridad y disponibilidad en tiempo y forma fue en ambos casos > 85%. No se identificaron patógenos raros en la región durante el torneo. Sólo el dengue y la influenza, ambos endémicos de la región, fueron identificados. El software de detección y alerta tempranosutilizado, identificó un total de 24 anomalías de 7 países, entre las cuales la gastroenteritis, los síntomas febriles y respiratorios, y las lesiones, alcanzaron las mayores proporciones. Todas las anomalías fueron investigadas rápidamente y en la mayor parte de los casos se encontró que se trataba de falsas alarmas. Se detectaron tres manifestaciones patológicas inusuales, todas de un mismo país. A todas se les dio respuesta oportuna, y no afectaron adversamente el curso del torneo. CONCLUSIONES: Las capacidades de vigilancia desarrolladas en la preparación y apoyo al torneo, contribuyeron a fortalecer y a poner a prueba los sistemas nacionales y regionales ya existentes para la vigilancia de enfermedades comunicables. Debe utilizarse eventos como éstos, a fin de fortalecer los sistemas de vigilancia ya existentes, y hacerlos suficientemente flexibles para responder a las condiciones cambiantes en eventos futuros.
