Abstract (Introduction): The search for techniques and methods for managing sludge generated during wastewater treatment is necessary to ensure sustainable sanitation in the medium term in Latin America. An interesting approach involves converting sludge into a biosolid usable in agriculture through alkaline sanitization. (Objective): We evaluated this technique’s efficacy and economic and environmental viability for obtaining an agriculturally usable type A biosolid from municipal wastewater treatment plant (WWTP) sludge. (Methodology): To this end, the efficacy in reducing microbiological parameters was experimentally tested at the laboratory scale using quicklime, for anaerobic and aerobic WWTP sludge. The experimental results fed a benefit/cost analysis model and a life cycle assessment. (Results): It was confirmed that applying a 40 % lime dose allowed the obtention of a type A biosolid with non-detectable concentrations of pathogenic microorganisms, which remained in that condition for more than 30 days. Additionally, the benefit/cost and life cycle analyses concluded that this option would be more attractive than sludge disposal in a landfill, due to the corresponding savings in chemical compounds (fertilizers, agricultural lime). (Conclusions): Therefore, alkaline sanitization can be considered suitable for WWTP sludge management. Its application on a larger scale should be further investigated in the country and the Latin-American region, considering the risk associated to the presence of heavy metals too.

Resumen (Introducción): La búsqueda de técnicas y modelos de gestión del lodo generado durante el tratamiento de las aguas residuales es necesaria para garantizar un saneamiento sostenible a mediano plazo en América Latina. Una vía interesante consiste en convertir el lodo en un biosólido aprovechable en la agricultura por medio de la higienización alcalina. (Objetivo): Se evaluó la eficacia y la viabilidad económica y ambiental de esta técnica para la obtención de un biosólido tipo A aprovechable en la agricultura a partir de lodo de planta de tratamiento de aguas residuales (PTAR) ordinaria. (Metodología): Para ello se probó experimentalmente en escala de laboratorio la eficacia en el decaimiento de parámetros microbiológicos higienizados con cal viva, usando lodo anaeróbico y aeróbico de PTAR. Los resultados experimentales alimentaron un modelo de análisis de beneficio/costo y de ciclo de vida. (Resultados): Pudo corroborarse que la aplicación de dosis de cal de 40 % permitió obtener un biosólido tipo A con concentraciones de microorganismos patógenos no detectables, lo cual se mantuvo en esa condición por más de 30 días. Además, el análisis de beneficio/costo y de ciclo de vida permitieron concluir que esta opción sería más atractiva que la disposición del lodo en un relleno sanitario, debido al ahorro correspondiente en compuestos químicos (fertilizantes o cal agrícola) derivado de su aprovechamiento. (Conclusiones): Por lo tanto, la técnica de higienización alcalina puede considerarse como adecuada para la gestión del lodo de PTAR y su aplicación a mayor escala debe investigarse en mayor detalle en el país y la región latinoamericana, considerando también el riesgo de presencia de metales pesados en este subproducto.

Antimicrobial resistance (AMR), in which microbes adapt to and resist current therapies, is a well-recognised global problem that threatens to reverse gains made by modern medicine in the last decades. AMR is a complex issue; however, at its core, it is driven by the overuse and inappropriate use of antimicrobials. Socioeconomic factors have been identified as significant contributors to the emergence and exacerbation of AMR, especially in populations facing inadequate access to healthcare, poor sanitation services and high morbidity and mortality rates. Weak healthcare systems and water, sanitation and hygiene have been highlighted as fundamental risk factors for AMR emergence and transmission. Behavioural factors, such as purchasing antibiotics without a prescription from a registered healthcare professional, not completing the prescribed course or overly prolonged courses of antibiotics, using antibiotics to treat viral infections, lack of access to quality antibiotics, and the proliferation of substandard or falsified (SF) drugs, have also been identified as significant contributors to AMR. Low- and middle-income countries have a higher incidence of antibiotics being dispensed without a prescription than higher-income countries.

Resumen Durante las últimas décadas en Puno, Perú, la problemática de la contaminación se fue agudizando por la acción combinada del crecimiento desordenado de la población urbana, gestión deficiente de residuos sólidos, descarga de aguas servidas sin tratamiento en la bahía del lago Titicaca y prácticas de sanidad e higiene inadecuadas; situaciones que afectan severamente el ambiente y la salud humana. El objetivo del estudio fue caracterizar las actitudes y comportamientos proambientales de la población de la ciudad de Puno en relación al saneamiento, la contaminación y la gestión ambiental. La investigación es no experimental, cuantitativa, trans¬versal, descriptiva, correlacional y nivel de análisis micro. El universo de estudio fue la población mayor de 18 años del área urbana, que comprende 97.264 habitantes; la muestra, deter¬minada al azar simple, fue de 382 personas. Se aplicó un cuestionario estructurado. El análisis descriptivo, inferencial y prueba de hipótesis se realizó con el software estadístico SPSS. Los resultados señalan que las actitudes ambientales de la mayoría de la población son positivas respecto a factores y fuentes de contaminación y efectos en la salud humana; contrariamente, las prácticas ambientales son inadecuadas en gestión ambiental en el hogar y condiciones de sanidad e higiene en la vivienda. Se concluye, que la mejora sostenible de actitudes y comportamientos proambientales, demanda de una nueva política pública de educación ambiental, cuya implementación incorpore la participación efectiva de la sociedad civil con base a un sistema de incentivos.

Abstract During the last decades in Puno, Peru, the problem of contamination has worsened due to the combined action of the disorderly growth of the urban population, poor management of solid waste, discharge of untreated sewage into the bay of Lake Titicaca and practices of inadequate sanitation and hygiene, severely affecting the environment and human health. The objective of the study was to characterize the pro-environmental attitudes and behaviors of the city’s population of Puno in relation to sanitation, pollution and environmental management. The research is nonexperimental, quantitative, cross-sectional, descriptive, correlational and micro level of analysis. The universe of study was the population over 18 years of age in the urban area, which comprises 97,264 inhabitants; the sample, determined at simple random, was 382 people. A structured questionnaire was applied. Descriptive and inferential analysis and hypothesis testing were performed with SPSS statistical software. The results indicate that the environmental attitudes of the majority of the population are positive regarding factors and sources of pollution and effects on human health. On the contrary, environmental practices are inadequate in environmental management in the home and health and hygiene conditions in the home. It is concluded that the sustainable improvement of pro-environmental attitudes and behaviors demands a new public policy of environmental education, whose implementation incorporates the effective participation of civil society based on an incentive system.

RESUMEN Esta reflexión emerge de un proyecto educativo orientado a mejorar algunos aspectos relacionados con el acceso y manejo del agua en tres barrios informales. El objetivo es reflexionar acerca de las nociones de territorio que se construyen en el contexto de proyectos educativos en comunidades que habitan barrios informales. El proyecto inició con la conformación de un grupo de participantes quienes realizaron la cartografía social de sus barrios para identificar aspectos críticos sobre agua y saneamiento. La validación de los mapas y los recorridos por cada sector aportaron elementos para los talleres relacionados con acceso, manejo, cuidado y derecho al agua, que posteriormente fueron multiplicados en cada comunidad. Este proceso permitió reconocer situaciones relacionadas con la negación del derecho al agua, el malestar, la tensión entre ilegalidad e informalidad, las maneras en que las comunidades resuelven sus necesidades y las relaciones que establecen con su territorio, en medio de grandes inequidades. En conclusión, existe una relación profunda entre salud y territorio, que se hace más evidente en comunidades en condiciones críticas. Los proyectos de educación para la salud requieren hacer un trabajo situado y establecer una mirada interdisciplinaria, que reconozca la complejidad e interdependencia de las dinámicas sociales y ambientales. informales saneamiento comunidad malestar informalidad inequidades conclusión críticas interdisciplinaria ambientales

ABSTRACT This reflection derives from an educational project focused on raising awareness about some aspects related to the access and management of water in three disadvantaged neighborhoods. The objective is to reflect on the notions of territory build in the context of educational projects in communities inhabiting disadvantaged neighborhoods. The project began with the formation of a group of participants who carried out social mapping of their neighborhoods to identify critical aspects of water and sanitation. Map validation and the paths followed in each sector provided the input to design the workshops, related to access, management, care and the right to water, which were subsequently multiplied in each community. This process allowed us to understand the situations derived from the denial of access to water, discomfort, and tension between illegality and informality as the modes people in these communities have chosen to address their needs, and the relationships they establish with their territory in the midst of huge inequalities. In conclusion, there is a deep relationship between health and territory which is blatant in communities that face critical life conditions. The projects on health education require situated work and to define an interdisciplinary perspective that acknowledges the complexity and interdependence of social and environmental dynamics. sanitation workshops community discomfort needs inequalities conclusion conditions dynamics

RESUMO A pandemia de covid-19 trouxe inúmeras mudanças aos territórios sustentáveis e saudáveis, implicando a necessidade de reorganização de estruturas sociais e de saúde. Objetivou-se compreender a dinâmica das feiras livres de vendas de alimentos no período pós-pandêmico de covid-19 em cidades do Maciço de Baturité, no Ceará, e avaliar as estratégias sanitárias e/ou de biossegurança utilizadas no enfrentamento da covid-19 por feirantes e consumidores. Realizou-se um estudo qualitativo entre outubro de 2021 e janeiro de 2023, em cinco cidades do Ceará. Em uma primeira etapa, foi realizada a observação das condições sanitárias e de biossegurança nas feiras livres, mediante um instrumento estruturado em quatro categorias. Em seguida, consumidores e feirantes foram entrevistados para o aprofundamento de discussões sobre os reflexos da pandemia sobre as feiras. Avaliaram-se as feiras de cinco cidades e entrevistaram-se 44 pessoas. Quatro cidades mostraram-se com condições sanitárias precárias e comprometimento da biossegurança e comercialização de alimentos. Feirantes e consumidores tiveram uma baixa percepção de risco sobre a covid-19 e levantaram a necessidade da perpetuação das feiras livres para a qualidade de vida e economia da região. As feiras livres são territórios sociais e econômicos sustentáveis, que ainda carecem de atenção por gestores e profissionais de saúde. covid19 covid 19 covid-1 saudáveis saúde Objetivouse Objetivou se póspandêmico pós pandêmico Baturité Ceará eou ou Realizouse Realizou 202 2023 etapa categorias seguida Avaliaramse Avaliaram entrevistaramse entrevistaram 4 pessoas mostraramse mostraram região covid1 1 covid- 20 2

ABSTRACT The COVID-19 pandemic has brought countless changes to sustainable and healthy territories, implying the need to reorganize social and health structures. The aim was to understand the dynamics of open-air food sales markets in the post-COVID-19 pandemic period in cities in the Maciço de Baturité, in Ceará, Brazil, and to evaluate the health and/or biosafety strategies used by marketers and consumers to deal with covid-19. A qualitative study was carried out between October 2021 and January 2023, in five cities in the state of Ceará. In the first stage, the sanitary and biosafety conditions at the street markets were observed using an instrument structured into four categories. Then, consumers and stallholders were interviewed to deepen discussions about the impact of the pandemic on the markets. We evaluated fairs in five cities and interviewed 44 people. Four cities were found to have precarious sanitary conditions and compromised biosafety in the sale of food. Marketers and consumers had a low-risk perception regarding COVID-19 and raised the need to perpetuate open-air markets for the region’s quality of life and economy. Free markets are sustainable social and economic territories, which still require attention from managers and health professionals.

ABSTRACT In the food industry, hygiene is a key condition to ensure food safety. That is why this work aimed to describe the visual, microbiological and bioluminescence methods used by food industries to verify sanitation procedures. The methodology was based on the review of the literature in the databases of Google Scholar, Scielo, Latindex, Dialnet, Redalyc and in food regulatory entities. The results showed that the food industries use the different cleaning and disinfection verification methods, either separately or jointly, to achieve compliance with the standards established by the reference regulations. In conclusion, the method used to verify the sanitation procedure resulted from the size of the company, the nature of the food, the processes applied and a series of factors that define the very identity of the industry, to guarantee quality. and food safety.

RESUMEN En la industria alimentaria, la higiene es una condición clave para asegurar la inocuidad de los alimentos. Es por ello, que este trabajo tuvo como objetivo describir sobre los métodos visual, microbiológico y de bioluminiscencia utilizados por las industrias de alimentos para la verificación de los procedimientos de saneado. La metodología se basó en la revisión de la literatura en las bases de datos de Google Académico, Scielo, Latindex, Dialnet, Redalyc y en entes reguladores de alimentos. Los resultados demostraron que las industrias de alimentos utilizan los diferentes métodos de verificación de limpieza y desinfección, ya sea de manera separada o conjunta para lograr cumplir con los estándares establecidos por las normativas de referencia. En conclusión, el método utilizado para la verificación del procedimiento de saneado dependerá de la envergadura de la empresa, la naturaleza del alimento, los procesos aplicados y de una serie de factores que definen la misma identidad de la industria, a fin de garantizar la calidad e inocuidad de los alimentos.

Abstract One of the elements of the mission programs on the frontiers of Spanish America was the creation of communities that conformed to norms established for urban planning by royal law, or, in other words, to the grid plan. Missionaries congregated thousands of indigenous peoples on the mission communities, and had them live in spatially compact living areas. Living in proximity to others helped spread highly contagious crowd diseases such as smallpox, and created hygiene problems. This article examines the urban plan and housing arrangements for indigenous peoples brought to live on the missions among the Guaraní and the California. It posits that the spatial organization of the mission communities and forms of housing were important factors in determining demographic patterns among the mission residents. It analyzes historic diagrams of the urban plan of selected mission communities in conjunction with a discussion of fertility and mortality patterns calculated from censuses and registers of baptisms and burials. The article confirms the hypothesis of the strong relationship between the urban plan, and demographic patterns. At the same time, it highlights differences between the two case studies presented. The Jesuits brought thousands of Guaraní to live on the mission communities created from whole cloth, and the large population densities facilitated the spread of contagion. Periodic epidemics killed thousands, but the populations recovered. On the California missions, chronic ailments such as syphilis and parasites from improper sanitation associated with living conditions were the major causes of mortality. The California mission populations did not recover.

Resumen Uno de los elementos de los programas misioneros en las fronteras de Hispanoamérica fue la creación de comunidades que se ajustaran a las normas establecidas para la planificación urbana por ley real, es decir, en el plano cuadriculado. Los misioneros congregaron a miles de indígenas en las comunidades de la misión y los hicieron vivir en áreas de vivienda espacialmente compactas. Vivir cerca de otros favoreció la propagación de enfermedades altamente contagiosas, como la viruela, y generó problemas de higiene. Este artículo examina el plan urbano y los arreglos de vivienda para los pueblos indígenas traídos a vivir en las misiones entre los guaraníes y los californianos. Postula que la organización espacial de las comunidades misioneras y las formas de vivienda fueron factores importantes en la determinación de los patrones demográficos entre los residentes de la misión. Analiza diagramas históricos del plan urbano de comunidades misioneras seleccionadas junto con una discusión de patrones de fertilidad y mortalidad calculados a partir de censos y registros de bautismos y entierros. Confirma la hipótesis de la fuerte relación entre el plan urbano y los patrones demográficos. Al mismo tiempo, destaca las diferencias entre sus dos estudios de caso: las misiones guaraníes donde las epidemias periódicas mataron a miles, pero las poblaciones se recuperaron; y las misiones californianas, donde las principales causas de mortalidad fueron las dolencias crónicas como la sífilis y los parásitos debidos a un saneamiento inadecuado asociado con las condiciones de vida, y cuyas poblaciones no se recuperaron.

Resumo Este estudo teve como objetivo analisar em que medida o crescimento socioeconômico e o acesso ao saneamento básico influenciam no desenvolvimento socioeconômico municipal da região Norte do Brasil, mensurado pelo Índice Firjan de Desenvolvimento Municipal (IFDM). Para isso, foi utilizado um painel de dados entre os anos de 2005-2016, analisados através das técnicas de estatísticas descritivas e regressão quantílica. Os resultados demonstraram que o atendimento com os serviços de esgotamento sanitário e abastecimento de água ainda estão distantes da universalização, ensejando políticas públicas de expansão do acesso. Nos modelos de regressão analisados, verificou-se que os PIBs setoriais influenciam positivamente no desenvolvimento na maioria dos quartis analisados. Já os serviços de saneamento básico tiveram resultado diferente do esperado: o abastecimento de água se mostrou associado negativamente ao IFDM, o que pode ser atribuído à queda no percentual da população atendida entre 2005 e 2013. Já o esgotamento sanitário influencia positivamente o IFDM somente nos municípios menos desenvolvidos, o que pode estar associado ao baixo provimento desses serviços na região. Este estudo joga luz para a necessidade de políticas públicas que tenham como intuito a ampliação do acesso ao saneamento na região, com ênfase nos serviços de abastecimento de água e esgotamento sanitário, possibilitando melhorias nos índices de desenvolvimento e contribuindo para a majoração na qualidade de vida dos cidadãos.

Abstract This study aimed to analyze the extent to which economic growth and access to basic sanitation influence the municipal economic development of the northern region of Brazil, measured by the FIRJAN Index of Municipal Development (IFDM). For this, a panel of data between the years 2005-2016 was used, analyzed using descriptive statistics and quantile regression techniques. The results showed that the service with sewage services and water supply is still far from universalization, giving rise to public policies to expand access. In the regression models analyzed, it was found that sectoral GDPs positively influence development in most of the analyzed quartiles. On the other hand, basic sanitation services had a different result than expected: water supply was negatively associated with the IFDM, which can be attributed to the drop in the percentage of the population served between 2005 and 2013. less developed municipalities, which may be associated with the low provision of these services in the region. This study sheds light on the need for public policies aimed at expanding access to sanitation in the region, with emphasis on water supply and sanitary sewage services, enabling improvements in development rates and contributing to an increase in quality of life of citizens.

Abstract The Cluster WASH (Water, Sanitation and Hygiene) is one of the cornerstones of humanitarian action, and a key element for the promotion of health worldwide. The recent years demonstrated the pressure on this humanitarian cluster, as a result of climate change. At the same time, it is also clear that WASH actions have a potential to foster health promotion, preparedness, and resilience among communities affected by humanitarian crisis related to climate hazards. This aspect is visible in both the existing literature of the major international organisations and NGOs networks acting in this field. It is also visible in the best practices promoted in two countries looked at in the paper: Bangladesh and the United States. This comparative analysis allows us to extract conclusions that may be replicable in other national or local contexts. It contributes to a better comprehension of the links between the humanitarian indicators and actions, and the imperative of a work with communities in order to improve even more the preparedness of the health impact of climate change.

Abstract The presence of Eristalis tenax in a dairy farm in the province of Salta is described. Larvae of E. tenax, known as "rat-tailed maggots", were found in large quantities on the premises, specifically in the feeding trough and waste pit. Taxonomic identification revealed distinctive morphological characteristics of the species. This finding expands the known geographical distribution of E. tenax in Argentina. Although the medical significance of these syrphids is relative, their ability to act as mechanical vectors of certain pathogens, such as mycobacteria, suggests the need to control their populations in anthropized environments. The importance of hygiene measures to prevent accidental ingestion of larvae is stressed, and monitoring of water tanks and pits is suggested. In conclusion, the relevance of recognizing the facultative nature of infestations is highlighted, along with the potential contribution of E. tenax control in sanitation measures of affected herds.

Resumen Este trabajo documenta la presencia de Eristalis tenax en un establecimiento lechero de la provincia de Salta. Las larvas de E. tenax, conocidas como "gusanos de cola de rata", se encontraron específicamente en el comedero y la fosa de desechos. La observación de las características morfológicas de la especie permitió su identificación taxonómica. Este hallazgo amplía la distribución geográfica conocida de E. tenax en Argentina. Aunque la importancia médica de estos sírfidos es relativa, se destaca su capacidad de actuar como vectores mecánicos de micobacterias, lo que sugiere la necesidad de controlar sus poblaciones en entornos antropizados. Se enfatiza la importancia de medidas de higiene para prevenir la ingestión accidental de larvas y se sugiere incorporar supervisión en depósitos de agua y piletones de decantación. En conclusión, se subraya la relevancia de reconocer la naturaleza facultativa de esta especie como posible vector y la contribución de su control en las medidas de saneamiento en rodeos afectados.

RESUMEN El objetivo de la investigación es analizar la incidencia de la inversión pública sobre la recaudación del impuesto predial en gobiernos locales provinciales de la macrorregión sur del Perú durante el período 2010-2020. El tipo de estudio es aplicado, bajo el enfoque cuantitativo, diseño no experimental, tipo longitudinal de panel, de carácter descriptivo y explicativo. Los datos para cada municipalidad provincial fueron extraídos del portal informativo del Ministerio de Economía y Finanzas (MEF) segmentadas mediante el análisis de conglomerados. El método de estimación econométrica toma en cuenta la metodología para datos longitudinales de panel. Teniendo en cuenta el análisis de conglomerados y las estimaciones econométricas, los resultados muestran que un incremento del 1% en la inversión pública en transportes, saneamiento y cultura y deporte, provocó un aumento en la recaudación del impuesto predial de aproximadamente 0,3182%, 0,1208% y 0,0923% respectivamente (primer clúster); un incremento del 1% en la inversión pública en transportes, cultura y deporte, provocó un aumento en la recaudación del impuesto predial de aproximadamente 0,2588% y 0,1434% respectivamente (segundo clúster); y un incremento del 1% en la inversión pública en transportes y saneamiento, provocó un aumento en la recaudación del impuesto predial de aproximadamente 0,2923% y 0,1377% respectivamente (tercer clúster).

ABSTRACT The objective of the research is to analyze the incidence of public investment on property tax collection in provincial local governments of the southern macro region of Peru during the period 2010 to 2020. The type of study is applied, under the quantitative approach, design non-experimental, longitudinal panel type, descriptive and explanatory. The data for each provincial municipality were extracted from the information portal of the Ministry of Economy and Finance (MEF) segmented through cluster analysis. The econometric estimation method takes into account the methodology for longitudinal panel data. Taking into account the cluster analysis and econometric estimates, the results show that a 1% increase in public investment in transportation, sanitation, and culture and sports, caused an increase in property tax collection of approximately 0.3182%, 0.1208%. and 0.0923% respectively (first cluster), a 1% increase in public investment in transport, culture and sports, caused an increase in property tax collection of approximately 0.2588% and 0.1434% respectively (second cluster) and an increase in the 1% in public investment in transportation and sanitation, caused an increase in property tax collection of approximately 0.2923% and 0.1377% respectively (third cluster).

Abstract Actions to combat COVID-19 exposed the ills of a historically unequal society, visible in precarious basic sanitation, loss of employment/income and increased poverty. With the main sources of data being the Comisión Económica para América Latina y el Caribe, the World Health Organization and the Brazilian Institute of Geography and Statistics, this article analyzes the impacts of the pandemic on social inequalities in Latin America, focusing on Brazil, preceded by a sociological debate on poverty, exclusion and inequality. The data indicates that the pandemic has intensified social inequalities, with the more privileged classes strengthening their positions and the poorest classes being drastically affected in different aspects depending on class, ethnic-racial, gender, age, conditions health, making them even more vulnerable to the risk of illness and death. Finally, there is an appeal for the construction of a less unfair and more supportive society, grounded on collective struggles, with a democratic and egalitarian society on the horizon.

Resumo As ações de combate à COVID-19 expuseram as mazelas de uma sociedade historicamente desigual, visíveis no precário saneamento básico, na perda de emprego/renda e no aumento da pobreza. Tendo como fontes principais dos dados a Comisión Económica para América Latina y el Caribe, a Organização Mundial de Saúde e o Instituto Brasileiro de Geografia e Estatística, este artigo analisa os impactos da pandemia nas desigualdades sociais na América Latina, com foco no Brasil, precedido por um debate sociológico sobre pobreza, exclusão e desigualdade. Os dados indicam que a pandemia intensificou as desigualdades sociais, com as classes mais favorecidas a reforçarem as suas posições e as classes mais pobres a serem drasticamente afetadas em diferentes aspetos, em função da pertença de classe, étnico-racial, de género, idade, condições de saúde, tornando-as ainda mais vulneráveis ao risco de doença e morte. Por fim, apela-se à construção de uma sociedade menos injusta e mais solidária, alicerçada em lutas coletivas, tendo no horizonte uma sociedade democrática e igualitária.

A dengue evoluiu de uma doença restrita a alguns países para um grave problema global de saúde pública, atingindo mais de 120 países nos últimos anos. No Brasil, após sua reintrodução em 1981, o país enfrentou diversas epidemias, com mais de 16 milhões de casos registrados até o momento. Em 2023, sob a vigência do fenômeno climático El Niño registrou-se uma das maiores epidemias de dengue no país, com mais de 1,6 milhões de casos notificados. Temperaturas e pluviosidade mais elevadas em conjunto com a circulação simultânea dos quatro sorotipos do vírus da dengue aumentaram ainda mais o risco de disseminação da doença em 2024, especialmente em populações sem imunidade para alguns dos sorotipos. Diante deste quadro, o Ministério da Saúde promoveu várias ações para enfrentar a situação, incluindo a instalação de uma Sala Nacional de Arboviroses e um Comitê de Operações de Emergência, repasses financeiros para apoiar estados e municípios em ações contingenciais de vigilância e prevenção de doenças, com ênfase no enfrentamento das arboviroses e investimentos em inovações para o controle da dengue, como vacinação e o método Wolbachia. Ainda assim, o primeiro trimestre de 2024 registrou um número de casos suspeitos de dengue superior ao de 2023, destacando a necessidade de aprimoramentos no monitoramento da situação epidemiológica para detecção precoce de epidemias e da preparação dos serviços de saúde para o cuidado dos casos com sinais de gravidade. Após mais de 40 anos de epidemias recorrentes, o controle efetivo da dengue no país requer ações sustentadas de prevenção por meio de estratégias inovadoras, envolvendo esforços coordenados de todas as esferas da gestão em saúde, juntamente com a participação ativa da população. Ações estruturais para a melhoria na cobertura de saneamento básico e para mitigação dos efeitos das mudanças climá

Dengue has evolved from a disease restricted to a few countries into a serious global public health issue, affecting over 120 countries in recent years. In Brazil, after its reintroduction in 1981, the country has faced several epidemics, with over 16 million cases registered to date. In 2023, under the influence of the El Niño climatic phenomenon, one of the largest epidemics occurred in the country, with over 1.6 million cases reported. High temperatures and precipitation in line with the simultaneous circulation of all four serotypes of the dengue virus increased the risk of disease spread in 2024, especially in populations without immunity to some of the serotypes. In such a scenario, the Ministry of Health undertook various actions to address the situation, including the establishment of a National Arbovirus Situation Room and an Emergency Operations Commitee, financial support to assist states and municipalities in contingency actions for disease surveillance and prevention, with an emphasis on combating arboviruses, and investments in innovations for dengue control, such as vaccination and the Wolbachia method. However, the number of notified dengue cases in the first trimester of 2024 supplanted the whole year of 2023, highlighting the need for a more effective monitoring of the epidemiological situation for early outbreak detection and the preparation of health services for the care of cases with signs of severity. After more than 40 years of recurrent dengue epidemics, the effective control of dengue requires sustained preventive actions using innovative strategies, with coordinated efforts at all levels of health management, along with active participation of the population. Structural actions to improve basic sanitation coverage and to mitigate the effects of climate change are critical conditions for reducing the burden of dengue in the population.
