Abstract This text analyzes, from the perspective of framing, how newspapers framed the “Spanish influenza” suffered by the inhabitants of Chiapas in 1918. It was found that initially, they tried to minimize the lethality of the disease, but when the deceased increased and was verified the seriousness of the situation, they highlighted the measures dictated by political and health authorities, the generated solidarity, and marginally the economic consequences. The most frequently used frame was human interest, followed by solutions/recommendations and attribution of responsibility, in a context where Chiapas was experiencing military conflicts, eventho these had already decreased, from the Mexican Revolution.

Resumen Este texto analiza, desde la perspectiva del framing, la forma en que los periódicos enmarcaron la “influenza española” que padecieron los habitantes de Chiapas en 1918. Se encontró que en un principio trataron de minimizar la letalidad de la enfermedad, pero cuando los fallecidos incrementaron y se comprobó la gravedad de la situación, destacaron las medidas dictadas por las autoridades políticas y sanitarias, la solidaridad generada y, de forma marginal, las consecuencias económicas. El frame que más se empleó fue de interés humano, seguido por el de soluciones/recomendaciones y de atribución de responsabilidad, en un contexto en el que Chiapas vivía enfrentamientos militares, aunque ya disminuidos, de la Revolución mexicana.

RESUMEN Introducción: La Vigilancia Centinela de las Infecciones Respiratorias Agudas Graves (IRAG) incluye el monitoreo y caracterización de casos hospitalizados. Objetivo: Describir las características clínico-epidemiológicas y agentes etiológicos de los adultos con IRAG en un hospital centinela en Paraguay. Metodología: Estudio observacional, descriptivo, de corte transversal, con recolección de datos retrospectivos de los pacientes adultos con IRAG hospitalizados en el Hospital Nacional de Itauguá entre junio de 2022 a agosto de 2023. La información se tomó de la base de datos del Sistema Nacional de Vigilancia Epidemiológica. Resultados: Se analizaron los datos de 1598 pacientes con IRAG, 820 varones (51,3%), 875 (54,8%) con 60 o más años, 1054 (66,0%) del departamento Central. El 79.2% (n=1265) de los pacientes presentaba algún factor de riesgo de gravedad o comorbilidad, 764 (47,8%) con hipertensión arterial. El 38.5% (n=632) fue admitido a UCI y la mortalidad fue de 34,7% (n=554). En el 13,8% (n=353) se confirmó SARSCoV-2, rhinovirus (1,7%), influenza A (1,5%), influenza B (0,6%), parainfluenza 3 (0,6%), VSR (0,2%), bocavirus (0,4%) e influenza AH1N1 (0,6%). Hubo significativamente mayor frecuencia de fallecidos en los de 60 años y más (40,7%), con algún factor de riesgo de gravedad (35,5% vs 25,9%) y en los confirmados con COVID-19 (38,2% vs 30,5%). Discusión: SARSCoV-2 sigue siendo el agente etiológico principal de las IRAG. El conocimiento de la epidemiología y los agentes virales es crucial para desarrollar estrategias de prevención y terapéuticas efectivas.

ABSTRACT Introduction: Sentinel Surveillance of Severe Acute Respiratory Infections (SARI) includes the monitoring and characterization of hospitalized cases. Objective: To describe the clinical-epidemiological characteristics and etiological agents of adults with SARI in a sentinel hospital in Paraguay. Methodology: Observational, descriptive, cross-sectional study, with retrospective data collection, of adult patients with SARI hospitalized at the National Hospital of Itauguá between June 2022 and August 2023. The information was taken from the database of the National System of Epidemiological surveillance. Results: The data of 1598 patients with SARI were analyzed, 820 men (51.3%), 875 (54.8%) aged 60 or older, 1054 (66.0%) from the Central department. 79.2% (n=1265) of patients had some risk factor or comorbidity, 764 with hypertension (47.8%). 38.5% (n=632) were admitted to the ICU and mortality was 34.7% (n=554). SARSCoV-2 was confirmed in 13.8% (n=353), rhinovirus (1.7%), influenza A (1.5%), influenza B (0.6%), parainfluenza 3 (0.6%), RSV (0.2%), bocavirus (0.4%) and Influenza AH1N1 (0.6%). There was a significantly higher frequency of deaths in those aged 60 years and over (40.7%), with some risk factor (35.5% vs 25.9%), and in those confirmed with covid-19 (38.2% % vs 30.5%). Discussion: SARSCoV-2 continues to be the main etiological agent of SARI in a sentinel hospital in Paraguay. Continued knowledge of the epidemiology and viral agents involved is crucial to developing effective prevention and treatment strategies.

Abstract There is currently a sensitive epidemiological moment in the country. There have been cases of patients with influenza who have died from pneumonia caused by superinfection of the Streptococcus pyogenes bacterium. There has been talk in the different media about a "new bacterium" and a "killer bacterium" or "flesh eating bacterium". Documentary evidence is presented of the presence of pneumonic symptoms superinfected by S. pyogenes in 1873 in Chile. The suitability of such terms is discussed in some depth, specially, the concepts of bacterial species, clone and related.

Resumen Se cursa actualmente un momento epidemiológico sensible en el país. Han aparecido casos de pacientes con influenza que han fallecido por neumonía causada por la sobreinfección de la bacteria Streptococcus pyogenes. Se ha hablado en los diferentes medios de prensa de una "nueva bacteria" y de una "bacteria asesina" o "come carne". Se presenta evidencia documental de la presencia de cuadros neumónicos sobreinfectados por S. pyogenes en 1873 en Chile. Se discute además sobre la idoneidad de tales términos, profundizando en los conceptos de especie bacteriana, clon y otros relacionados.

ABSTRACT Introduction: Influenza is a global threat, with high epidemic potential and affects between 5 and 15% of the world's population annually. In the hospital environment, vaccination is crucial to protect healthcare professionals. However, despite international recommendations, vaccination uptake is low due to safety concerns and/or distrust. Studies show that vaccinated professionals have lower rates of absenteeism, and when infected with the virus, they present milder symptoms. In this work, a retrospective cross-sectional observational study is carried out on the vaccination rate against this disease in a population of hospital-based workers, from 2019 to 2023. To understand the importance of vaccination against Influenza in these workers and which behavioral determinants may justify considering this evolution, we carried out a review of the challenges of vaccination among health professionals and identified key points to develop strategies with the aim of promoting adherence to vaccination campaigns. Methodology: For the observational study, vaccination data from hospital health professionals by the Occupational Health Service was used, recorded on a specific form at the time of administration. Professional category was the only variable considered. Data analysis was performed using Microsoft® Excel®. For the review, the databases Medline, Science Direct and Google Scholar were used, with the keywords "Influenza vaccine”, “health professional” and “behaviour”, selecting studies from 2010 to 2024. From the result of 1277 works, the exclusion criteria, which included vaccination for other diseases and target populations that did not include health professionals, 22 bibliographic sources were selected. To reflect the national reality, articles on the topic published by the Revista Portuguesa de Saúde Ocupacional Online were included, as well as complementary studies and reference documents. Results: The study of adherence to flu vaccination in this hospital peripheral to Lisbon, between 2019 and 2023, showed a variation in vaccination adherence, with an average of 30%, a value below the ones reported in other countries. The categories most hesitant about this vaccine were Nursing Staff and Technical Assistants; at the opposite extreme, there was greater adherence from Medical Personnel and Technical Assistants. During the COVID-19 Pandemic, an increasing number of professionals were vaccinated annually, with this trend reversing after the end of the global emergency of this disease. From the review of the literature on vaccine hesitancy, 8 of the 14 behavioral domains stand out that represent theories of behavioral change that constitute modifiable factors that influence behavior in relation to the vaccine. We approach each of them from this perspective, namely: knowledge, the environmental context and resources, social influence, beliefs and knowledge about consequences, beliefs about individual capacity, identity and social/professional role, reinforcement and emotion. Discussion: Flu vaccine hesitancy among healthcare professionals can be a cause of morbidity and mortality for patients. Understanding the barriers and motivation for healthcare professionals to adhere to flu vaccination campaigns is crucial. Professionals who are asymptomatic carriers become sources of transmission. Annual vaccination, although safe and effective, faces variability due to antigenic concordance. In Portugal, educational and communication strategies are vital, highlighting the role of health professionals as models of preventive behavior. Easy access to medical consultations and Occupational Health recommendations is associated with greater adherence. In times of pandemic, the propensity for vaccination has increased, and it is important to promote this change. Strategies adapted to the cultural context are essential to boost adherence to Influenza vaccination among healthcare professionals. Conclusion: The approach to combating barriers and promoting vaccination among healthcare professionals must involve multiple areas and multiple levels, with communication targeted at specific groups, to increase its effectiveness. The message must be adapted to different population groups and different levels of health literacy. Knowing these behavioral determinants can help develop vaccination promotion campaigns from new perspectives and finding strategies to increase vaccination coverage is crucial for Occupational Health Services. Due to the ethical characteristics of the professions involved in providing direct care to patients, there is a need to reinforce the idea that vaccination among healthcare professionals is not only for their benefit, but above all for the protection of their patients.

RESUMO Introdução: A Gripe é uma ameaça global, com alto potencial epidémico e afeta anualmente entre 5 a 15% da população mundial. No ambiente hospitalar, a vacinação é crucial para proteger os Profissionais de Saúde. No entanto, apesar das recomendações internacionais, a adesão é baixa devido a preocupações de segurança e/ou desconfiança. Estudos mostram que os profissionais vacinados têm menores taxas de absentismo e, perante infeção pelo vírus, apresentam sintomatologia mais ligeira. Neste trabalho é realizado um estudo observacional transversal retrospetivo da taxa de vacinação contra esta doença numa população de trabalhadores de base hospitalar, no período de 2019 a 2023. Para compreender a importância da vacinação contra a Influenza nestes trabalhadores e quais os determinantes comportamentais que podem justificar esta evolução, realizou-se uma revisão dos desafios da vacinação entre Profissionais de Saúde, para identificar pontos chave e elaborar estratégias com o objetivo de promover a adesão às campanhas de vacinação. Metodologia: Para o estudo observacional da taxa de adesão à vacinação contra a Gripe num hospital periférico foram utilizados os dados de vacinação dos Profissionais de Saúde disponibilizados nos registos do Serviço de Saúde Ocupacional. A categoria profissional foi a única variável considerada. A análise dos dados foi realizada com o Microsoft® Excel®. Para a revisão recorreu-se às bases de dados Medline, Science Direct, Google Scholar; com as palavras-chave "Influenza vaccine”; “health professional” e “behaviour" e filtraram-se estudos de 2010 a 2024. Resultaram 1277 trabalhos e, após aplicar os critérios de exclusão, que incluíam vacinação para outras doenças e populações alvo que não os Profissionais de Saúde, foram selecionadas 22 fontes bibliográficas. Para espelhar a realidade nacional foram incluídos os artigos sobre o tema publicados pela Revista Portuguesa de Saúde Ocupacional Online, assim como estudos complementares e documentos de referência. Resultados: O estudo da adesão à vacinação contra a Gripe neste hospital periférico a Lisboa, entre 2019 e 2023, mostrou uma variação na adesão à vacinação, com uma média de 30%, valor abaixo dos valores reportados noutros países. As categorias com maior hesitação a esta vacina foram o Pessoal de Enfermagem e os Assistentes Técnicos. Na situação oposta estavam o Pessoal Médico e os Assistentes Técnicos. Durante a Pandemia COVID-19 existiu um número crescente de profissionais vacinados anualmente, tendo esta tendência invertido após o fim da emergência global desta doença. Da revisão da bibliografia sobre a hesitação vacinal destaca-se 8 dos 14 domínios comportamentais que representam as teorias de mudança comportamental que constituem fatores modificáveis que influenciam a atitude em relação à vacina. Abordou-se sobre esta perspetiva cada um deles, nomeadamente, o conhecimento; o contexto ambiental e recursos; influência social; crenças e conhecimento sobre consequências; bem como sobre a capacidade individual; identidade e papel social/profissional; reforço e emoção. Discussão: A hesitação vacinal contra a Gripe entre Profissionais de Saúde pode ser uma causa de morbilidade e mortalidade para os doentes. Compreender as barreiras e motivação para a adesão dos Profissionais de Saúde às campanhas de vacinação contra a Gripe é crucial. Profissionais portadores assintomáticos, tornam-se fontes de transmissão. A vacinação anual, embora segura e eficaz, enfrenta variabilidade devido à concordância antigénica. Em Portugal, estratégias educacionais e de comunicação são vitais, destacando o papel dos Profissionais de Saúde como modelos de comportamento preventivo. O acesso fácil a consultas médicas e tal ser recomendado pela Saúde Ocupacional é associado a maior adesão. Em tempos de pandemia, a propensão à vacinação aumentou, importando promover esta mudança. Estratégias adaptadas ao contexto cultural são essenciais para impulsionar a adesão à vacinação contra a Gripe entre Profissionais de Saúde. Conclusão: A abordagem para combater as barreiras e promover a vacinação nos Profissionais de Saúde deve envolver múltiplas áreas e vários níveis, com uma comunicação dirigida a grupos específicos, para aumentar a sua eficácia. Deve adaptar-se a mensagem aos diferentes grupos populacionais e aos diferentes níveis de literacia em saúde. Conhecer estes determinantes comportamentais pode ajudar a desenvolver campanhas de promoção da vacinação a partir de novas perspetivas e encontrar estratégias para aumentar a cobertura vacinal é crucial para os Serviços de Saúde Ocupacional. Pelas características éticas das profissões envolvidas na prestação de cuidados diretos aos doentes, existe a necessidade de reforçar a ideia de que a vacinação entre Profissionais de Saúde não é apenas para seu benefício mas, acima de tudo, para proteção dos seus doentes.

The laboratory became relevant due to the arrival of the 2019 new coronavirus pandemic: 511,225 nasopharyngeal exudate samples and 14,568 determinations were processed for the diagnosis of human immunodeficiency viruses, hepatitis C and B, and human papilloma carried out on the COBAS 4800® platform. In 2023, the pathogen detection capacity was strengthened and the community cocirculation of influenza A and B, parainfluenza virus type 4, the OC 43 coronavirus, SARS-CoV-2 and dengue was identified. Conclusions: the progressive increase in the resolution capacity of the Molecular Biology Laboratory, together with the implementation of new diagnostic platforms, has allowed us to strengthen the detection of pathogens of clinical interest and improve virological sentinel surveillance.

Abstract Objective: To evaluate if the comorbidity and coinfections presented by SARS-CoV-2 infection vs. COVID-19 impact our Mexican children. Method: Prospective and observational study that included the 2020-2021 peak influenza season. All patients with a diagnosis of infection by SARS-CoV-2 vs. COVID-19 who were admitted to the Hospital Infantil de Mexico were analyzed. Real-time RT-PCR for SARS-CoV-2 was performed in all patients, determining E, RdRp and RP genes and protein N, as well as RT-PCR for detection of respiratory viruses. Results: The inclusion criteria were met by 163 patients. The group with the highest risk of becoming ill was adolescents (40.4%), followed by schoolchildren and preschoolers (21.4% and 19.6% of the cases, respectively). There were three cases with viral coinfection: two (1.2%) with parvovirus B-19 and one (0.6%) with herpes type I; another two (1.2%) showed bacterial coinfection. The main comorbidity were obesity, acute lymphoblastic leukemia and arterial hypertension. Regarding mortality, we only had four cases (2.4%). Conclusions: Obesity, cancer, hypertension, heart disease and diabetes are comorbidity present in our patients, as referred to in literature, but not coinfections. In our study, we did not have any associated mortality related to comorbidity.

Resumen Objetivo: Evaluar el impacto de la comorbilidad y de las coinfecciones presentadas por la infección por SARS-CoV-2 vs. COVID-19 en niños mexicanos. Método: Estudio prospectivo y observacional que comprendió la temporada alta de influenza 2020-2021, analizando todos los pacientes con diagnóstico de infección vs. enfermedad por SARS-CoV-2 vs. COVID-19 que ingresaron al Hospital Infantil de México. Se realizó en todos RT-PCR en tiempo real para SARS-CoV-2, determinando gen E, gen RdRp, gen RP y proteína N, y RT-PCR multiplex para detección de virus respiratorios. Resultados: Los criterios de inclusión los cumplieron 163 pacientes. El grupo con mayor riesgo de enfermar fueron los adolescentes (40.4%), seguidos de los escolares y preescolares (21.4% y 19.6% de los casos, respectivamente). Hubo tres casos con coinfección viral: dos (1.2%) con parvovirus B-19 y uno (0.6%) con herpes tipo I; hubo otros dos (1.2%) con coinfección bacteriana. La principal comorbilidad correspondió a obesidad, leucemia linfoblástica aguda e hipertensión arterial. En cuanto a mortalidad, solo hubo cuatro casos (2.4%). Conclusiones: Obesidad, cáncer, hipertensión, cardiopatías y diabetes constituyen la comorbilidad en nuestros pacientes, como se refiere en la literatura, no así las coinfecciones. En nuestro estudio no hubo casos de mortalidad relacionada con la comorbilidad.

Abstract The present work studies and analyzes six books of the sick and two books of the sick of the Hospital Juanino de Nuestra Señora de los Desamparados of the city of Tezcoco elaborated in the XVIII century; but it focuses its attention on three important epidemics that struck the local population in 1737 (Matlazahuatl), 1784 (Influenza) and 1813 (Typhus). These manuscripts have remained in historiographic oblivion and their analysis allows us to know the ages, origin and “sickness” that were treated in a hospital during the eighteenth century.

Resumen El presente trabajo estudia y analiza seis libros de enfermos y dos de enfermas del hospital juanino de Nuestra Señora de los Dolores, de la ciudad de Tezcoco, elaborados en el siglo XVIII. La atención estará centrada en tres importantes epidemias que azotaron a la población local en 1737 (matlazahuatl), en 1784 (influenza) y en 1813 (tifo). Dichos manuscritos han permanecido en el olvido historiográfico y su análisis permite conocer las edades, procedencia y “enfermad” que era atendida en un hospital durante el siglo XVIII.

Résumé Cet article étudie et analyse huit ouvrages rédigés au XVIIIème par des patients, dont deux par des femmes, provenant de l’Hôpital Nuestra Señora de los Dolores de la ville de Tezcoco, fondé par l’ordre des Frères de la Charité (Juaninos). Il se focalise sur trois épidémies importantes qui ont frappé la population locale en 1737 (Matlazahuatl), 1784 (grippe) et 1813 (typhus). Ces manuscrits sont restés dans l’oubli historiographique mais leur analyse nous offre des informations essentielles sur l’âge, la provenance et le type de maladie des personnes qui étaient prises en charge dans un hôpital au XVIIIème.

RESUMEN Introducción. Durante 2020 y 2021, la circulación de los virus influenza se mantuvo por debajo de lo esperado en todo el mundo. En Argentina, en el año 2022 observamos una circulación ininterrumpida de influenza todo el año. Nuestros objetivos fueron describir los patrones de circulación y las características clínicas de niños internados con influenza. Población y métodos. Estudio retrospectivo, analítico, observacional. Se incluyeron todos los niños internados en un centro pediátrico con detección del virus influenza durante los años 2019-2022. Resultados. Se internaron 138 pacientes en 4 años; en 2019 se observó una tasa del 4,5/1000 egresos hospitalarios mientras que en 2022, fue del 15,1/1000. En 2020 y 2021 no hubo casos. En el 2019 la mayoría de los casos ocurrieron en invierno, la causa de la internación fue la infeccción respiratoria aguda baja (IRAB) en el 79 % y se detectó influenza A en el 92 % de los casos. En el 2022, la mayoría de los casos ocurrieron en primavera, el 62 % presentó IRAB y en el 56 % se detectó influenza A. Ambos períodos tuvieron similares frecuencias de vacunación y de comorbilidades. Conclusiones. En el 2022 se registraron más internaciones por influenza, lo que podría corresponder a que se realizaron métodos diagnósticos moleculares, que son más sensibles, y se observó un cambio en la estacionalidad con más casos en primavera. En 2019 predominó influenza A en infecciones del tracto respiratorio inferior, mientras que en el 2022 influenza A y B fueron similares, y hubo más formas extrapulmonares.

BACKGROUND: Dentistry is regarded as a high-risk profession due to increased levels of exposure to oral secretions, aerosols and fomites that harbour infectious microorganism. Yet evidence indicates poor uptake of vaccines against HBV and, most recently, Covid-19. This study sought to investigate the predictors of Covid-19 vaccination intention among oral health professionals in South Africa. METHODOLOGY: In 2022, a representative national sample of oral health professionals was surveyed using an online questionnaire. Consenting practitioners provided demographic data, information on vaccination history and five psychological antecedents of Covid-19 vaccine. Data analysis was undertaken using SPSS ver. 29.0. RESULTS: Our findings indicate high vaccination intention rate among the OHPs (77.9%), especially those with history of influenza vaccination (OR=2.65, p=0.003). The was a positive correlation between the 5C psychological antecedents (confidence and collective benefit) and intention to vaccinate. Positive Covid-19 diagnosis did not affect vaccination intention. CONCLUSION: Most oral health professionals intended to get the Covid-19 vaccination. For those showing low willingness to vaccinate, psychological antecedent factors such as complacency and calculation should be addressed to improve vaccination intention and uptake.

RESUMEN Introducción: A nivel mundial, la cobertura de vacunación contra el COVID-19, así como contra la influenza es baja tanto en la población general como en los profesionales de la salud a pesar de que la vacuna es gratuita y obligatoria en el personal sanitario. Objetivo: Describir la cobertura de vacunación contra el COVID -19, y la influenza en personal de salud y administrativo de un hospital de referencia del Ministerio de Salud Pública y Bienestar Social en el periodo 2021-2022. Metodología: Estudio observacional descriptivo de corte trasverso. Se hizo la revisión de los registros del personal sanitario y administrativo del centro vacunatorio del Hospital Nacional de Itauguá de la campaña vacunal contra el COVID-19 y de anti-influenza en el periodo 2021- 2022. Resultados: De los 3.586 funcionarios, 999 (27,9 %) eran médicos, 1494 (41,7 %) personal de enfermería, 366 (10,2 %) otra categoría de personal sanitario, y 727 (20,3 %) personal administrativo. En forma global, el 86,5 % de los funcionarios recibió por lo menos las dos dosis que constituyen el esquema primario y el 73 % la dosis de refuerzo. El 2,1 % del personal no recibió ninguna dosis de vacuna anti covid-19, la cifra fue mayor en el personal administrativo (4,8 %). La cobertura de vacunación contra la influenza fue de 20 % en el 2021 y 25 % en el 2022. Discusión: Si bien cobertura de vacunación anti-COVID-19 fue comparable a otros países, la vacunación contra la influenza fue muy baja. Es urgente implementar estrategias dirigidas a aumentar la percepción de riesgo y aceptabilidad de las vacunas obligatorias para el personal sanitario.

ABSTRACT Introduction: Worldwide, vaccination coverage against COVID-19, as well as against influenza, is low both in the general population and in health professionals, despite the fact that the vaccine is free and mandatory for health personnel. Objective: To describe the COVID -19 and influenza vaccination coverage in health and administrative personnel of a reference hospital of the Ministry of Public Health and Social Welfare in the period 2021-2022. Methods: Cross-sectional descriptive observational study. Charts of the health and administrative personnel of the vaccination center of the Itauguá National Hospital of the COVID-19 and influenza vaccination campaign in the period 2021-2022 were reviewed. Results: Of the 3,586 personnel, 999 (27.9%) were medical personnel, 1,494 (41.7%) nursing personnel, 366 (10.2%) other category of health personnel, and 727 (20.3%) administrative personnel. Overall, 86.5% of the employees received at least the two doses that constitute the primary schedule and 73% the booster dose; 2.1% of the staff did not receive any dose of the anti COVID-19 vaccine, which was higher in the administrative staff (4.8%). Influenza vaccination coverage was 20% in 2021 and 25% in 2022. Discussion: Even though the vaccination coverage of anti-COVID-19 was comparable to other countries, vaccination anti-influenza was very low. It is urgent to implement strategies aimed at increasing the perception of risk and acceptability of mandatory vaccines for health personnel.

Abstract It starts from emotions as psychic and social constructions, with meaning, that circulate and configure climates, groups and subjects. This text focuses on the review of disgust or social disgust, anger and hatred, or hateful speech, and it is reflected from different perspectives, through the consultation of bibliography and documentation. There is also an approach to a case, the influenza pandemic in Mexico, how the fear that was felt, evolved or was complemented by other feelings. Regarding findings, highlight the importance of the emotions studied, their validity as part of sociality, their circulation and combination, their role in the mind, the body, above all, in culture and social practices. In addition, how in a pandemic situation, several emerge, exacerbate, interweave or combine, with force and political consequences that shape and feed back into the social system.

Resumen Se parte de las emociones como construcciones psíquicas y sociales, con significado, que circulan y configuran climas, grupos y sujetos. Este artículo se centra en la revisión de la repugnancia o asco social, la ira y el odio o, en su caso, los discursos odiosos. Se reflexiona desde diversas perspectivas, por medio de la consulta de bibliografía y documentación. También tiene acercamiento a un caso, la pandemia de influenza en México, tomado para determinar de qué manera el miedo se sintió, evolucionó o se complementó con otros sentimientos. Respecto a sus hallazgos, este trabajo destaca la importancia de las emociones estudiadas, su vigencia como parte de la socialidad, su circulación y combinación, su papel en la mente, el cuerpo, sobre todo, en la cultura y las prácticas sociales. También, pretende indagar cómo afloran las emociones en una coyuntura de pandemia, cómo se exacerban, entretejen o combinan con fuerza y consecuencias políticas que configuran y retroalimentan el sistema social.

ABSTRACT Cardiovascular diseases stand as the leading cause of mortality among adults globally. For decades, comprehensive evidence has underscored the correlation between infections, particularly those involving the respiratory system, and an elevated risk of cardiovascular and cerebrovascular events, as well as all-cause mortality. The mechanisms through which infections heighten cardiovascular events are intricate, encompassing immune system activation, systemic inflammation, hypercoagulable states, sympathetic system activation, and increased myocardial oxygen demand. Respiratory infections further contribute hypoxemia to this complex interplay. These mechanisms intertwine, giving rise to endothelial dysfunction, plaque ruptures, myocardial depression, and heart failure. They can either instigate de novo cardiovascular events or exacerbate pre-existing conditions. Compelling evidence supports the safety of influenza, pneumococcal, herpes zoster, COVID-19 and respiratory syncytial virus vaccines in individuals with cardiovascular risk factors or established cardiovascular disease. Notably, the influenza vaccine has demonstrated safety even when administered during the acute phase of a myocardial infarction in individuals undergoing angioplasty. Beyond safety, these vaccinations significantly reduce the incidence of cardiovascular events in individuals with an augmented cardiovascular risk. Nevertheless, vaccination rates remain markedly suboptimal. This manuscript delves into the intricate relationship between infections and cardiovascular events. Additionally, we highlight the role of vaccinations as a tool to mitigate these occurrences and reduce residual cardiovascular risk. Finally, we emphasize the imperative need to optimize vaccination rates among individuals with heart diseases.

RESUMEN Los adultos fumadores, con comorbilidades, y los ancianos tienen mayor riesgo de contraer infecciones pulmonares y de tener peor evolución. La neumonía adquirida en la comunidad debida a virus, neumococo, además de otras bacterias y microorganismos “atípicos” afecta tanto a adultos sanos como enfermos. La vacuna antigripal se diseña el verano anterior orientada a las cepas esperadas para la temporada siguiente. Su eficacia depende fundamentalmente de la variante viral que finalmente sea la responsable del brote. La vacuna anti-neumocócica polisacárida existe desde 1983 y será inexorablemente reemplazada por vacunas conjugadas de mayor eficacia, que previenen la infección por los serotipos presentes en la vacuna. La inmunización contra SARS-CoV-2 aceleró la reducción del contagio y la gravedad de COVID-19 notablemente. La vacuna acelular para Bordetella pertussis no está en el calendario de adultos, aun cuando vacunarlos fortalece el control del contagio infantil. La vacunas doble bacteriana (difteria y tétanos), y triple (doble + pertusis), y contra sarampión, varicela, rubeola, HPV, Haemophylus influenzae, meningococo, herpes zóster, fiebre hemorrágica argentina y fiebre amarilla están disponibles, pero son de uso limitado. Nuevas vacunas, como la recientemente aprobada por los CDC contra el virus sincicial respiratorio, pronto estarán disponibles.

ABSTRACT Adult smokers, subjects with comorbidities, and the elderly are at higher risk of pulmonary infections and worse outcomes. Community-acquired pneumonia due to viruses, pneumococcus, other bacteria, and “atypical” microorganisms affects healthy and sick adults. The flu vaccine is designed the previous summer for the strains expected for the following season. Its effectiveness depends fundamentally on the viral variant ultimately responsible for the outbreak. The anti-pneumococcal polysaccharide vaccine has been available since 1983 and it is expected to be replaced by conjugate vaccines which are more effective in preventing infection due to serotypes present in the vaccine. Immunization against SARS-CoV-2 diminished contagion and severity of COVID-19 remarkably. The acellular vaccine for Bordetella pertussis is not on the schedule for all adults, even when vaccinating them strengthens the control of contagion in children. Double bacterial (diphtheria and tetanus), triple (double + pertussis), measles, varicella, rubella, HPV, Haemophilus influenzae, meningococcal, herpes zoster, Argentine hemorrhagic fever, and yellow fever vaccines are available, but their use is limited. New vaccines such as the one recently approved by the CDC against respiratory syncytial virus will soon be available.

RESUMEN Los adultos fumadores, con comorbilidades, y los ancianos tienen mayor riesgo de contraer infecciones pulmonares y de tener peor evolución. La neumonía adquirida en la comunidad debida a virus, neumococo, además de otras bacterias y microorga nismos “atípicos” afecta tanto a adultos sanos como enfermos. La vacuna antigripal se diseña el verano anterior orientada a las cepas esperadas para la temporada siguiente. Su eficacia depende fundamentalmente de la variante viral que finalmente sea la responsable del brote. La vacuna anti-neumocócica polisacárida existe desde 1983 y será inexorablemente reemplazada por vacunas conjugadas de mayor eficacia, que previenen la infección por los serotipos presentes en la vacuna. La inmunización contra SARS-CoV-2 aceleró la reducción del contagio y la gravedad de COVID-19 notablemente. La vacuna acelular para Bordetella pertussis no está en el calendario de adultos, aun cuando vacunarlos fortalece el control del contagio infantil. La vacunas doble bacteriana (difteria y tétanos), y triple (doble + pertusis), y contra sarampión, varicela, rubeola, HPV, Haemophylus influenzae, meningococo, herpes zóster, fiebre hemorrágica argentina y fiebre amarilla están disponibles, pero son de uso limitado. Nuevas vacunas, como la recientemente aprobada por los CDC contra el virus sincicial respiratorio, pronto estarán disponibles.

ABSTRACT Adult smokers, subjects with comorbidities, and the elderly are at higher risk of pulmo nary infections and worse outcomes. Community-acquired pneumonia due to viruses, pneumococcus, other bacteria, and “atypical” microorganisms affects healthy and sick adults. The flu vaccine is designed the previous summer for the strains expected for the following season. Its effectiveness depends fundamentally on the viral variant ultimately responsible for the outbreak. The anti-pneumococcal polysaccharide vaccine has been available since 1983 and it is expected to be replaced by conjugate vaccines which are more effective in preventing infection due to serotypes present in the vaccine. Immuniza tion against SARS-CoV-2 diminished contagion and severity of COVID-19 remarkably. The acellular vaccine for Bordetella pertussis is not on the schedule for all adults, even when vaccinating them strengthens the control of contagion in children. Double bacterial (diphtheria and tetanus), triple (double + pertussis), measles, varicella, rubella, HPV, Haemophilus influenzae, meningococcal, herpes zoster, Argentine hemorrhagic fever, and yellow fever vaccines are available, but their use is limited. New vaccines such as the one recently approved by the CDC against respiratory syncytial virus will soon be available.
