Texto completoInfluenza and acute respiratory viral diseases remain relevant health problem both in Ukraine and in the world. Important is control over their distribution among the population, prevention and prediction of epidemics and pandemics. Deaths from flu and its complications ranks first among all infectious diseases. The structure of mortality are among the leaders 65rokiv older patients - 80 - 90%. Much of the prevalence, property damage, social and medical consequences clearly confirm the need to combat them. Due to the extreme variability of the pathogen influenza and currently remains uncontrolled infection that necessitates its further research to solve this problem on a global scale.

Texto completoIntroduction: Thousands of people die from influenza or its complications each year despite the fact that it is one of the few vaccine preventable diseases. Immunocompromised cancer patients are among the most vulnerable to this infection and flu‐related complications, and therefore vaccination is highly recommended in these patients; however, current vaccination rates and attitudes towards vaccination remain unknown. We hypothesize that immunization rates are lower than the 100% recommendation rate, and hope to understand the reasoning behind the discrepancy. The purpose of this study is to assess cancer patient attitudes towards influenza vaccination in an effort to minimize barriers to vaccination and eventually increase vaccination rates in this immunocompromised population. Methods: Cancer patients enrolled in phase I clinical oncology trials at the Virginia G Piper Cancer Center at Scottsdale Healthcare were invited to participate in a voluntary survey. The 15‐item survey consisted of demographic information, knowledge regarding the flu vaccine, vaccination status after cancer diagnosis and while on treatment, and general attitudes towards vaccination. A total of 84 cancer patients completed the survey. Results were stratified by age, gender, education level, and vaccination status. As this was a descriptive study, no statistical analyses were performed. Results: A total of 84 (n=84) advanced cancer patients enrolled in phase I clinical oncology trials completed the survey. Results indicate that although 71% of patients received the vaccine prior to cancer diagnosis, only 58% of patients have received the vaccine since their cancer diagnosis, and only 48% have been vaccinated while on cancer treatment. Of those vaccinated since cancer diagnosis, 94% reported doctor recommendation of the vaccine and most vaccinate to protect themselves from the virus. Of those not vaccinated since cancer diagnosis, only 37% report their doctor recommends the vaccine and the majority avoid vaccination because they believe the vaccine can cause the flu, they do not feel at risk of infection, and they do not believe the vaccine is effective. Conclusion: Our findings suggest that although the CDC strongly recommends influenza vaccination in cancer patients due to the risk of secondary complications and even death in these immunocompromised individuals, vaccination rates remain low. Our data demonstrates that patients who receive a doctor recommendation for the vaccine are more likely to be vaccinated, but not all doctors recommend the vaccine. Furthermore, false information regarding the vaccine, its efficacy, and its ability to cause infection continues to deter patients from vaccination. Together, this information offers profound insight into the cancer patient population and suggests the need for increased physician and patient education regarding the benefits of annual influenza vaccination to improve vaccination rates and decrease influenza infection and complications in the future.

Texto completoAs birds throughout Asia, Europe, and Africa have been infected with an avian influenza, public health experts everywhere are worried that if spread to humans, the world could face a pandemic with proportions similar to the 1918 Spanish influenza. In the past, the federal government has been more concerned with foreign militaries than foreign diseases. But today, the government has devoted over $7.1 billion to preventing a potential pandemic. While much of this goes to research and the production of vaccinations, money is also allocated to strengthen local infrastructures and control the disease in other countries. The fact that the federal government has put so much time and effort to prevent a disease that has affected few humans worldwide, let alone any Americans, points to a growing belief in human security rather than national security. This thesis will evaluate the concept of human security and argue that U.S. action and public opinion regarding the threat of an avian flu pandemic clearly shows decision-making based on human security

Texto completoA gripe é uma das doenças infecciosas com maior impacto na história da humanidade devido às pandemias ocorridas nos últimos 100 anos. Nos suínos, o vírus influenza é responsável pela Doença Respiratória Aguda associada a elevados prejuízos económicos. A importância da vigilância epidemiológica do vírus influenza em suínos reside no facto desta espécie ser susceptível à infecção por vírus de origem suína, aviar e humana. A infecção dum mesmo animal com diferentes estirpes e/ou subtipos pode resultar na geração dum novo vírus. Durante a redacção da presente dissertação, o aparecimento duma nova estirpe do subtipo H1N1 fez com que suspendesse esta tarefa durante uma quinzena para acompanhar a evolução da infecção no Homem. No entanto, à data de entrega desta dissertação não está demonstrado que esta nova estirpe tenha tido origem em suínos. O trabalho foi realizado na sequência dum estágio realizado no Centre de Recerca en Sanitat Animal (Barcelona, Espanha) em 4 explorações localizadas na Comunidade Autónoma da Catalunha. A colheita de amostras biológicas foi acompanhada da realização dum inquérito epidemiológico aos produtores. As amostras de sangue de animais de 20 semanas de idade e de reprodutoras foram analisadas num teste ELISA e posteriormente pela inibição da hemaglutinação. Foi realizada uma análise estatística descritiva dos resultados obtidos que são concordantes com os estudos europeus consultados. De facto, os subtipos H1N1, H1N2 e H3N2 cocirculam nas suiniculturas por todo o mundo com predominância do subtipo H3N2 (100%) nas explorações investigadas; existe diferença significativa das seroprevalências (p<0,05) entre animais de 20 semanas de idade e reprodutoras; os sistemas de produção, as características das explorações e as medidas de biossegurança implementadas influenciam a seroprevalência do vírus influenza. A vigilância da emergência de novos subtipos no suíno deve integrar a vigilância dos vírus aviares e humanos, principalmente nas áreas de maior risco, onde as elevadas densidades animais favorecem o contacto entre espécies susceptíveis. É importante desenhar, testar e implementar uma rede de vigilância epidemiológica da gripe suína em Portugal. As pandemias de H5N1 e de gripe mexicana (H1N1), ainda em evolução, são exemplos de cenários epidemiológicos mas também sócio-económicos e políticos que requerem este tipo de informação para tomadas de decisão de Saúde Humana e Animal.
ABSTRACT - The importance of influenza virus is reported in our history by the pandemics of flu during the last 100 years. Swine influenza virus, responsible for Acute Respiratory Disease, has an important economic impact. Swine are susceptible to different influenza virus, as avian, human or swine, being the concomitant infection of the same animal with several strains and/or subtypes determinant for the generation of a new virus. This factor illustrates the importance of a constant epidemiological surveillance. The elaboration of the present thesis was suspended by the recent emergence of a new H1N1 strain, to monitor the international progression of the disease and the knowledge about the biology of the virus. Even though, it was not confirmed that the swine was the origin of this new virus. This report is the result of 4 months of internment ship at CReSA - Centre de Recerca en Sanitat Animal (Barcelona, Spain). Four herds located in Catalunha (Barcelona, Spain) were used for sampling sows and pigs with 20 weeks age. All blood samples were tested by ELISA and the positive ones were confirmed by hemagglutination inhibition. Descriptive statistical analyses were performed with the hemagglutination inhibition results. Our findings are similar to those found by other researchers. Three subtypes – H1N1, H1N2 and H3N2 - cocirculate in most herds worldwide. In this study, H3N2 showed a seroprevalence of 100%; seroprevalences were significantly higher (p<0,05) in sows than in pigs at 20 weeks of age; seroprevalences were influenced by the production system, the herd type and biosecurity measures. Swine influenza surveillance must embrace both avian and Human viruses, specially in higher density areas where there is an increased risk for interspecies contact. The implementation of a network of epidemiological surveillance for swine flu is crucial for its prevention and control in Portugal. H5N1 and Mexican flu (H1N1), still progressing, are examples of pandemic, where socio-economic and political events required an accurate control and information on the behalf of Public and Animal Health.

Texto completoInfluenza A has a segmented genome of eight single-stranded, negative-sense RNAs packed into ribonucleoproteins (vRNPs). This segmentation allows reassortment between different strains with the potential to create highly virulent, pandemic new strains. A packaging mechanism is supposed, ensuring the incorporation of one copy of each segment species into budding virions. En route from the nucleus to budding at the plasma membrane, the vRNPs are thought to form multisegment complexes via RNA-RNA and RNP-RNP interactions called packaging signals. This process is not yet completely understood. Here, a new RNA-FISH method (MuSeq-FISH) was introduced to overcome the spectral limits of multiplexing in order to visualize all IAV vRNA and mRNA targets of the human strain A/Panama. An image processing pipeline including image registration, spot detection, automated colocalization analysis and combinatorial analysis was developed, capable of high data throughput. For the first time, a complete map of the localization and abundance of all viral RNAs in individual cells has been generated. This data enabled detailed investigations about the mechanisms and potential hierarchies within the packaging process, which were inferred from pathways and statistical analysis of over 60 individual cells with more than 105 vRNP occurrences. We also gained information about the abundance and cell-to-cell heterogeneity of vRNPs among large sets of infected cells, unravelling that infection environments even in neighboring cells differ strongly in segment composition with an impact on packaging. In addition, conditional probability modelling was conducted to infer reaction constants from inherently static FISH data. We have extended this analysis to the avian strain A/Mallard and the reassortant strains A/Pan-M, A/Pan-NS and A/Pan-NSM, which contain reassorted genomes of A/Panama and A/Mallard. Here we have shown that packaging dynamics and networks differ widely, even among closely related strains. Packaging processes in these strains seemed to be very diverse, however we found A/Pan-M and A/Pan-NS to more closely resemble A/Mallard in terms of packaging. First steps have been taken to extend the method into different directions: combi- nation of MuSeq-FISH with STED imaging is in principle possible and has been applied for simultaneous detection of three vRNA species. MuSeq-FISH was also applied to single IAV virions directly after cell entry in order to study their genome content, where we found segments 7 and 8 to be lacking most frequently. In addition, a system of pHW2000-based plasmids expressing only mRNA has been created for almost all A/Panama segments. The functionality of this system was shown in a proof of concept, so that its use in transfection experiments can serve as a potential instrument to investigate vRNP packaging in artificial infection-like conditions with reduced vRNAs sets of choice. MuSeq-FISH together with its image analysis pipeline will be a useful tool also for other biological questions, especially concerning high-grade colocalization. Further understanding of the vRNP packaging in influenza can help us to understand the emergence of pandemic strains and open up paths to new antiviral medication.

Resumo: Esta dissertação de mestrado do grupo de biomatemática do Instituto de Matemática Aplicada e Computacional da UNICAMP, com auxílio de Bolsa de mestrado da CNPq, é resultado de dois anos, 2008 e 2009, de estudo a respeito da dispersão do risco de contágio do H5N1. Após tratar brevemente da estrutura viral; do papel das aves que sofrem sua ação; dos problemas financeiros que o H5N1 traria ao Brasil e já inflingiu em outras nações; o trabalho concentra-se em modelar e simular um ambiente formado de duas populações de comportamento distinto. A primeira, de aves silvestre, livres, que podem migrar. A segunda população consiste de aves restritas ao controle de um criador; não voam, não se espalham além dos limites da pequena localidade onde são criadas para fins de subsistência. Cada uma das três subdivisões destas populações, de acordo com o status em relação à doença, é modelada por uma equação diferencial parcial, compondo um sistema cuja solução numérica, necessária por conta das descontinuidades das condições iniciais, prediz o comportamentos da infecção em função do tempo e do espaço. Dentre os resultados alcançados, destaca-se: o homem parece ter chance de conter o espalhamento do vírus. Para isso teria de sacrificar todos os animais de pequenas criações e, então indivíduos da população silvestre, mas a uma taxa menor do que eles são capazes de se reproduzir, ou seriam levados a extinção. Também estão contidos neste trabalho, o estudo dos estados estacionários do sistema e a estimativa de que o coeficiente de difusão do H5N1 assumiria valores entre 0,025 e 0,5 km²/dia
Abstract: This dissertation from the IMECC, UNICAMP, Biomathematical Group, with funds offered by CNPq, is the result of two years, 2008 and 2009, of study about the spreading of H5N1 risk of infection. After treating briefly the viral structure; the birds that suffer the virus; the financial problems that the disease would bring to Brazil and has already inflicted to other nations; this paper concentrates in modeling and simulating an environment composed by two distinct behaviour population. The first one is free wild birds, that migrate. The second population consists of birds restricted to a farmer control; they don't fly, don't spread beyond little farms limits where they are raised to subsistence purposes. After dividing each of these two populations in order three, acording to their status in relation to the H5N1 infection, they are modeled by means of Partial Differential Equation, composing a non-linear system which requires numerical solution because of descontinuous inicial conditions and predicts the infection behaviour in spatial and temporal terms. Among the results figure: Humans, by completely sacrifing small farms birds and, then, wild birds in smaller rate than they reproduce themselves, seems to have a chance of prevent the virus to spread even further. This paper also study stationary states and determine, through computational methods, the H5N1 coefficient range, among 0.025 and 0.5 km²/day

Texto completoIn 1918, the Spanish flu pandemic killed an estimate number of between 50 and 100 million people worldwide. 40 years later a new influenza pandemic, the Asian flu spread throughout the world. The Asian flu hit a large proportion of the world’s population but the case-fatality rate was lower and an estimated number of 2 to 4 million people died in the pandemic. In order for today’s governments to formulate good preparedness plan for future influenza pandemics, studying previous pandemics can give better understanding of how the community might be affected. The aim of this study was to investigate the effects of the Asian flu pandemic on the Swedish military forces. By seeing if the regiment was affected by the Asian flu one can then assume that the whole society was affected. Data from Swedish regiments has been collected from the Defence Medical Administration Service at the National Archives and processed trough SPSS. The findings show that there where an increase of the amount of sick as well as the number of sick leaves during 1957 compared to previous and later years. Because of the increase in sick leaves one can draw the conclusion that the society has a great risk of being influenced. Hence, a preparedness plan will be even more important. Conclusion: The community is affected by influenza pandemic in both an economical and a societal level. The effects are short in time since infected recover quite quick. However, there are effects which could be better handled if the government is prepared and has conducted a plan for when the next pandemic influenza strikes.

We analyze its symptoms Spanish flu, as well as highlight the imprecision of medicine to define and characterize it, the multiple symptoms diagnosed and the variety of treatments and therapeutic measures. For this, the research is anchored in the records of the press Goiás, in the context of 1918/1919 were lodged with the population and called Advice to people: that is, they were indications of health authorities to combat the Spanish flu. More than a biological problem, the Spanish flu became a social problem, and as such has been analyzed here, from its social representation - ie, the disease constituted a problem that requires an explanation by the company attacked, it is imperative that has a social and cultural. Historicize diseases is one of the ways to understand a society.
A pesquisa sobre a gripe espanhola em Goiás teve como principal objetivo compreender os impactos e os significados que representou para a população. Buscamos analisar a sintomatologia da doença de gripe espanhola, bem como ressaltar a imprecisão da medicina ao defini-la e caracterizá-la, os múltiplos sintomas diagnosticados e a variedade de tratamentos e medidas terapêuticas. Para tanto, a pesquisa ancorou-se nos registros da imprensa goiana, que, no contexto de 1918/1919, foram dirigidos à população e denominados Conselhos ao povo;ou seja, eram indicações das autoridades sanitárias para o combate da gripe espanhola. Mais que um problema biológico, a gripe espanhola se tornou um problema social, e como tal foi aqui analisada, a partir da sua representação social ou seja, a doença constituiu-se um problema que exige uma explicação pela sociedade atacada; é imperativo que tenha sentido social e cultural. Historicizar as doenças é um dos caminhos para se compreender uma sociedade.

Material and methods: We performed a cross-sectional study in 592 students from a private university in Lima to evaluate the relationship between the frequent use of public transport and the presence of influenza-like illness (ILI). Self-report of ILI was defined as fever plus cough or sore throat in last two weeks, most used type of transport to go to university. OR crude and adjusted were calculated used simple and multiple logistic regression. Results: 12.0% (71/592) had ILI in the past two weeks. Use of public transport (OR = 3.6; 95% CI 1.2 to 10.2) and have contact with someone with ILI at home (OR = 1.8; 95% CI 1.1 to 3.1) were found associated in multiple logistic regression model. No association with age, vaccination against influenza, living with children, smoke and pathological history. In conclusion, the use of public transport is associated with the presence of ILI in a group of university students from Lima.

Texto completoPurpose: The purpose with this study is to analyze if the Swedish authorities and media had different ways of discussing the new influenza, in connection with the pandemic classification June 11, 2009. This is the first time an influenza has been classified as a pandemic since the Hongkong-influenza in1968. Methodology: The method used for the study is discourse analysis, aqualitative method that gives the opportunity to study not only what is said, but how things are said. In this thesis, the aim is to study how the image ofthe new influenza is transmitted via the texts. The texts have been analysed based on:- General and underlying themes- Words and concepts used- Persons/sources quoted or referred to- Historical connections/historical backgroundTheoretical perspectives: The study is based on theories about socialconstructionism and discourse analysis. Conclusions: the conclusions drawn from the study show that the media textsare more dramatic and sensational when it comes to describing the newinfluenza. The Swedish authorities have a more fact-based and calming tone towards the public. Within the analyzed material, it is possible to seedifferences between the discourses, also when describing the same themes. Within some themes, resemblances have been identified between the mediadiscourse and the authorithy discourse.

Texto completoSwine influenza is an enzootic infection affecting 50% of the French livestock. The infection can be unnoticed but can also induce high morbidity among batches of affected animals, resulting in lower production performance and significant economic losses. The severity of influenza A virus in pig is influenced by many factors such as the virus strain, husbandry practices, the immune status of animals, concomitant infections with other respiratory pathogens, etc. In the same way, various epidemiological forms of influenza exist in farms. Thus, infections can be repeated in all successive batches within a farm, especially among young animals with passive immunity. In order to better understand the clinical and epidemiological diversity of the swine flu, and help develop appropriate strategies to control the disease, we tried to bring new knowledge about factors that promote the exacerbation of the flu syndrome and/or its recurrence, and more generally to give new information about the mechanisms underlying the pathogenesis of influenza viruses in pigs, in relation to the response of the infected host. Firstly, we compared, through experimental infections of specific pathogen free pigs, the pathogenicity of the two swine influenza viruses mostly detected in pigs in France, i.e. one from the European “avian-like swine H1N1” lineage (H1avN1) and the other one from the European “human-like reassortant swine H1N2” lineage (H1huN2), each one alone or in co-infection with Mycoplasma hyopneumoniae (Mhp), another respiratory pathogen widespread in French farms. We showed that the H1huN2 infection induced a more marked pathology than the H1avN1 infection, and that Mhp pre-infection induced the exacerbation of the H1avN1, but not the H1huN2, infection. Then, we used the Mhp/H1avN1 co-infection model to evaluate alternative approaches that could reduce the impact of influenza infections and their complications: firstly, a supply of compounds with antioxidant properties in food; and secondly, a feed restriction of short duration. In both cases, we showed beneficial effects on zootechnical parameters the days following influenza infection. This work has also brought new knowledge on modulation of oxidative stress markers in plasma, as well as metabolic changes following the co-infection with Mhp and H1avN1 in pigs. The severity of flu clinical manifestations being related, among other, to the quality of the immune responses developed by the infected host, we studied these responses in pigs experimentally infected by H1avN1 and assessed the impact of factors such as the presence of Mhp or maternal derived antibodies on these responses. We showed that the viral infection induced inflammation and interferon response. The Mhp pre-infection exerted an additive effect on inflammation of lung tissue and may promote the virus persistence in the lung. Finally, we have shown that the presence of maternally-derived immunity protected the piglets clinically but did not prevent viral shedding, delayed the T cell response and strongly inhibited the post-infectious humoral response. However, despite the failed humoral immune response, animals were completely protected from a second infection occurring when maternal antibodies had disappeared. Therefore, this work have brought new knowledge on factors influencing influenza infection in pig as well as the underlying mechanisms, which is a prerequisite for improving disease control. They allow, between-other, to consider improving the health and welfare of animals by acting on their diet
