Reemergencia de la encefalitis equina del oeste (WEEV) en la Argentina: una revisión de aspectos epidemiológicos, virológicos y clínicos de relevancia / Reemergence of western equine encephalitis in Argentina

La encefalitis equina del oeste (WEEV, por su sigla en inglés, Western Equine Encephalitis) es una enfermedad reemergente en Argentina a partir del año 2023. La co-municación inicial fue en 1933, las últimas epizootias ocurrieron en 1983 y el último caso humano se registró en 1996. Se revisan las características del agente causal, la ecología con especial referencia a los vectores iden-tificados en el país, su competencia en la transmisión y el ciclo así como los factores de riesgo para adquirir la enfermedad. La situación epidemiológica en equinos y humanos desde noviembre 2023 hasta marzo 2024 es analizada. Se describen las formas clínicas de presen-tación de la enfermedad humana, las posibilidades evo-lutivas, los datos disponibles en los casos confirmados y el tratamiento. La metodología y algoritmo empleados para el diagnóstico etiológico en el Centro Nacional de Referencia son detallados. Las estrategias para la pre-vención y el control se basan en la vacunación de los equinos, el saneamiento ambiental y el control del foco ante la presentación de la enfermedad animal (vigilancia epidemiológica activa)

Western equine encephalitis (WEE) is a re-emerging dis-ease in Argentina starting in 2023. Since the initial notifi-cation in 1933, the last epizootics occurred in 1983, and the last human case was recorded in 1996.The charac-teristics of the causative agent, the ecology with special reference to vectors identified in the country, their compe-tence in transmission, and the cycle as well as the risks factors for acquiring the disease, are reviewed.The epidemiological situation in horses and humans from November 2023 to March 2024 is analyzed. The clinical presentation of the human disease, its evolutionary po-tential, available data in confirmed cases, and the treat-ment are described.The methodology and algorithm used for the etiological diagnosis at the National Reference Center are detailed. Strategies for prevention and control are based on vaccination of horses, environmental sani-tation and outbreak control in the presence of the animal disease (active epidemiological surveillance)

Prophylaxis and treatment of diseases in western São Paulo state: the Sanitation Service and trachoma in the early twentieth century. / A profilaxia e o tratamento das enfermidades do oeste paulista: o Serviço Sanitário e o tracoma no princípio do século XX.

In 1906, Emílio Ribas reorganized the Sanitation Service and centralized São Paulo state public health services in the state capital. A campaign to combat trachoma, an ophthalmic disease, was implemented as part of this project. This article analyzes this campaign, which provided care for the sick living on rural properties in a process that predated the 1917 Rural Sanitary Code. The empirical data was obtained from government reports, decrees, medical journals and newspapers. We conclude that Ribas, by creating an organization that integrated the efforts of the sanitary districts and the Trachoma Commission medical teams, sought to form a complex apparatus to combat the diseases present in both urban areas and the countryside.

Em 1906, Emílio Ribas reorganizou o Serviço Sanitário e centralizou na capital os serviços de saúde pública do estado de São Paulo. Nesse projeto, a campanha de combate ao tracoma, uma enfermidade oftálmica, foi implantada. Este artigo analisa essa campanha que atendeu os enfermos das propriedades rurais em um processo que antecedeu ao Código Sanitário Rural de 1917. O material empírico foi composto por relatórios governamentais, decretos, periódicos médicos e jornais. Concluímos que Ribas, ao criar uma estrutura que unificou os esforços dos distritos sanitários com as equipes de atendimento das Comissões do Tracoma, buscou formar um complexo aparato para combater as enfermidades presentes tanto nas áreas urbanas quanto na zona rural.

The right to water: Impact on the quality of life of rural workers in a settlement of the Landless Workers Movement, Brazil.

Access to water for rural populations is vital not only for personal consumption and hygiene but also for food production, income generation and cultural practices. To deepening the understanding of this issue, this research addressed the access to water in a settlement of the Landless Workers Movement. The perspective of the Human Rights to Water and Sanitation was used as a theoretical framework, assessing how inadequate access to water impacts the quality of rural populations. A qualitative research was used, through participant observation and individual interviews with 12 rural workers, living at the Ulisses Oliveira settlement. The findings reflect that water is not sufficiently available to meet the community's social, economic and cultural needs and that such conditions can lead to a loss of identity. Therefore, access to water must be understood in the light of its political, social and cultural dimensions and the Human Rights to Water and Sanitation can be used as an instrument to public policies.

Social control in the sectors of sanitation and health: a comparative analysis based on the Brazilian legal framework. / O controle social em saneamento e em saúde: análise comparativa com base nos marcos legais federais brasileiros.

Comparison between federal Brazilian legal frameworks in the areas of health and sanitation, from the perspective of participation, is the thread of this work, considering the pioneering of health and its possible influence on sanitation. The comparative effort was made from six analytical criteria: defined social control mechanisms; character given to social control; responsibility, recommendations and support to enable social control; access to information; control over the use of resources; control of the implementation of the resolutions. It was evaluated if the sanitation framework have been helped by health formulations and if have achieved produce more effective practices of social control in the conduct of public policy. The results show that, although it has received some influence from the health area, the water and sanitation framework is more restricted and has less potential to produce more effective practices, since it presents: 1) more restrictive mechanisms because they are not necessarily deliberative; 2) lack of a policy of training counselors and popular education to incentive participation; 3) absence of effective mechanisms for monitoring the use of resources.

A comparação entre os marcos legais federais brasileiros das áreas de saúde e de saneamento, sob a perspectiva do controle social, é o fio condutor deste trabalho, tendo em vista o pioneirismo da primeira e sua possível influência sobre a segunda. O esforço comparativo foi realizado a partir de seis critérios analíticos: mecanismos de controle social definidos; caráter conferido ao controle social; responsabilidade, recomendações e apoio para viabilizar o controle social; acesso à informação; controle sobre o uso dos recursos; controle da implementação das deliberações. Avaliaram-se possibilidades de o marco do saneamento se beneficiar das formulações no campo da saúde e lograr produzir práticas mais efetivas de controle social na condução dessa política pública. Os resultados revelam que, mesmo tendo recebido alguma influência da área de saúde, o marco do saneamento é mais restrito e tem menor potencialidade de produzir práticas mais efetivas, uma vez que apresenta: 1) mecanismos mais restritivos por não serem necessariamente deliberativos; 2) ausência de uma política de formação de conselheiros e de educação popular como incentivo e fortalecimento ao controle social; 3) ausência de mecanismos efetivos voltados para a fiscalização do uso dos recursos.

A Dialectical and Dialogical Approach to Health Policies and Programs: The Case of Open Defecation in India.

A multi-pronged approach to health policy and programs related to open defecation (OD) is proposed via a qualitative study conducted in rural India. A dialogic and dialectic perspective is employed to interpret the key findings from nine focus groups, highlighting the dialectical views toward OD and latrines. Findings indicate that current policy may be too narrow as it does not fully deal with the multiple reasons, including social communication as well as gender, cultural, health and work identity issues, for OD. The results suggest that OD is more complicated than it appears and a multi-pronged, poly-vocal approach to health communication campaigns and policy should be considered.

Hygienic Requirements of Urban Living Environment in the Russian Federation and in Italy: a comparison.

AIM: Urban planning tries to contain and regulate the uncontrolled growth of cities, encouraging their sustainable development at environmental, social and health levels. In the present work, the authors compare the regulatory frameworks of the Russian Federation and of Italy, with particular attention paid to the urban aspects of living spaces. METHODS: Considering the extant normative production in the two countries, the authors examine national legislation for Italy and federal legislation for Russia, mainly taking into account the following aspects: urban planning tools and environmental and sanitary protection of living spaces. RESULTS: Hygienic-sanitary requirements regarding living environment in Russia are essentially expressed by two regulatory systems (SNiP and SanPiN), while in Italy they are regulated by the D.M. 07/05/1975. The main principles of urban planning in Russia are expressed by federal standards, while in Italy they are incorporated in the Municipal General Plan (PRG) and in the various local regulations, where all the superordinate regulations are summarized. Finally, aspects related to environmental quality in both countries are governed by various specific laws (federal and state); a complex system of rules that take into account potential impacts on health and the environment. CONCLUSIONS: The authors reckon that clear and updated regulatory tools should be developed, especially in Italy that lags behind, regarding the building and urban hygiene, relying on the most recent acquisitions of international scientific literature in order to guarantee the highest standards in Public Health safeguard.

Situation of Water, Sanitation and Hygiene and Diarrhoeal Diseases After Open Defecation Free Declaration.

BACKGROUND: Makwanpur district was declared Open Defecation Free in 2013 as the movement started in Nepal since 2003 to address the high burden of diarrhoeal disease among under five children. As the water supply, sanitation and hygiene situation of the district is not known after the declaration, the need for this study was visualized. METHODS: It was a cross sectional study among randomly sampled 178 households using interview and observation. Water, sanitation and hygiene situation was assessed in terms of related facilities, knowledge and practices of mothers. Results were compared with the standard open defecation free criteria of Nepal. Five years trend of diarrhoeal disease was analysed from the health facility records to assess the impact of declaration. RESULTS: Of the total households 92% had toilets and 90% had access to improved water source. About 79% mothers had high knowledge on safe water, sanitation and hygiene and 43% practiced hand washing with soap at critical times. Proper disposal of solid and liquid waste was found among 32% and 46% of households respectively. About 68% of households had good water, sanitation and hygiene situation and was found to be significantly associated with related knowledge among mothers irrespective of their economic status. Diarrhoeal disease among under five children was found declining after open defecation free declaration. CONCLUSIONS: Water, sanitation and hygiene status in the study area is found lower than the criteria for open defecation free declaration. However, diarrhoeal disease among children under five is declining after the declaration.

[Hygienic and sanitary aspects in urban planning: contradiction in national and local urban legislation regarding public health]. / Aspetti igienico-sanitari in ambito urbanistico: conflittualità nelle norme urbanistiche nazionali e locali in tema di sanità pubblica.

Nowadays, the majority of world population lives in urban areas and this portion is going to increase in the coming decades. The health impact of urban areas is well established and described in scientific literature. Italian health and hygiene legislation dealing with urban health is fragmented and not coordinated with the regulation about environment and city planning. The overlapping of legal competences between different authorities and the conflict of attribution between the Central State and Regional Governments deeply contributed to generate uncertainty. The authors here analyse the Italian regulatory framework and depict its lacks in terms of public health protection.

The broiler meat system in Nairobi, Kenya: Using a value chain framework to understand animal and product flows, governance and sanitary risks.

Livestock food systems play key subsistence and income generation roles in low to middle income countries and are important networks for zoonotic disease transmission. The aim of this study was to use a value chain framework to characterize the broiler chicken meat system of Nairobi, its governance and sanitary risks. A total of 4 focus groups and 8 key informant interviews were used to collect cross-sectional data from: small-scale broiler farmers in selected Nairobi peri-urban and informal settlement areas; medium to large integrated broiler production companies; traders and meat inspectors in live chicken and chicken meat markets in Nairobi. Qualitative data were collected on types of people operating in the system, their interactions, sanitary measures in place, sourcing and selling of broiler chickens and products. Framework analysis was used to identify governance themes and risky sanitary practices present in the system. One large company was identified to supply 60% of Nairobi's day-old chicks to farmers, mainly through agrovet shops. Broiler meat products from integrated companies were sold in high-end retailers whereas their low value products were channelled through independent traders to consumers in informal settlements. Peri-urban small-scale farmers reported to slaughter the broilers on the farm and to sell carcasses to retailers (hotels and butcheries mainly) through brokers (80%), while farmers in the informal settlement reported to sell their broilers live to retailers (butcheries, hotels and hawkers mainly) directly. Broiler heads and legs were sold in informal settlements via roadside vendors. Sanitary risks identified were related to lack of biosecurity, cold chain and access to water, poor hygiene practices, lack of inspection at farm slaughter and limited health inspection in markets. Large companies dominated the governance of the broiler system through the control of day-old chick production. Overall government control was described as relatively weak leading to minimal official regulatory enforcement. Large companies and brokers were identified as dominant groups in market information dissemination and price setting. Lack of farmer association was found to be system-wide and to limit market access. Other system barriers included lack of space and expertise, leading to poor infrastructure and limited ability to implement effective hygienic measures. This study highlights significant structural differences between different broiler chains and inequalities in product quality and market access across the system. It provides a foundation for food safety assessments, disease control programmes and informs policy-making for the inclusive growth of this fast-evolving sector.

Doing implementation research on health governance: a frontline researcher's reflexive account of field-level challenges and their management.

BACKGROUND: Implementation Research (IR) in and around health systems comes with unique challenges for researchers including implementation, multi-layer governance, and ethical issues. Partnerships between researchers, implementers, policy makers and community members are central to IR and come with additional challenges. In this paper, we elaborate on the challenges faced by frontline field researchers, drawing from experience with an IR study on Village Health Sanitation and Nutrition Committees (VHSNCs). METHODS: The IR on VHSNC took place in one state/province in India over an 18-month research period. The IR study had twin components; intervention and in-depth research. The intervention sought to strengthen the VHSNC functioning, and concurrently the research arm sought to understand the contextual factors, pathways and mechanism affecting VHSNC functions. Frontline researchers were employed for data collection and a research assistant was living in the study sites. The frontline research assistant experienced a range of challenges, while collecting data from the study sites, which were documented as field memos and analysed using inductive content analysis approach. RESULTS: Due to the relational nature of IR, the challenges coalesced around two sets of relationships (a) between the community and frontline researchers and (b) between implementers and frontline researchers. In the community, the frontline researcher was viewed as the supervisor of the intervention and was perceived by the community to have power to bring about beneficial changes with public services and facilities. Implementers expected help from the frontline researcher in problem-solving in VHSNCs, and feedback on community mobilization to improve their approaches. A concerted effort was undertaken by the whole research team to clarify and dispel concerns among the community and implementers through careful and constant communication. The strategies employed were both managerial, relational and reflexive in nature. CONCLUSION: Frontline researchers through their experiences shape the research process and its outcome and they play a central role in the research. It demonstrates that frontline researcher resilience is very crucial when conducting health policy and systems research.

Política de saneamento básico no Brasil: discussão de uma trajetória / Basic sanitation policy in Brazil: discussion of a path

Resumo O artigo demonstra que a posição de dominância das empresas estaduais de saneamento condiciona o processo decisório da política pública de saneamento no Brasil. A hegemonia dessas empresas é aqui explicada por meio da análise de uma trajetória que foi capaz de criar incentivos políticos e econômicos que permitiram sua consolidação no tempo. A partir da análise de conteúdo da legislação proposta para o setor e do material produzido pelos grupos de interesse envolvidos na aprovação de um novo marco regulatório setorial em 2007, o trabalho identifica as principais fontes de incentivo instituídas pela adoção do Plano Nacional de Saneamento que explicariam determinados aspectos estruturais na política atual de saneamento e sua forte resiliência às inovações propostas no contexto democrático.

Abstract This article demonstrates that the position of dominance enjoyed by state sanitation companies dictates the public policy decision-making process for sanitation in Brazil. These companies’ hegemony is explained here through the analysis of a path that generated political and economic incentives that have permitted its consolidation over time. Through the content analysis of the legislation proposed for the sector and the material produced by the stakeholders involved in the approval of new regulations for the sector in 2007, the study identifies the main sources of incentive introduced by the adoption of the National Sanitation Plan, which explain certain structural features of the current sanitation policy and its strong capacity to withstand the innovations proposed under democratic rule.

Sanitary Transportation of Human and Animal Food. Final rule.

The Food and Drug Administration (FDA or we) is issuing a final rule to establish requirements for shippers, loaders, carriers by motor vehicle and rail vehicle, and receivers engaged in the transportation of food, including food for animals, to use sanitary transportation practices to ensure the safety of the food they transport. This action is part of our larger effort to focus on prevention of food safety problems throughout the food chain and is part of our implementation of the Sanitary Food Transportation Act of 2005 (2005 SFTA) and the Food Safety Modernization Act of 2011 (FSMA).

[Food Sanitation Act and Minamata Disease].

Immediately after the official recognition of Minamata disease (1956.5.l) a study group at Kumamoto University suggested that Minamata disease was caused by food poisoning. The next year, this suggestion was accepted by the Ministry of Health and Welfare (MHW). Prior to the decision to apply the Food Sanitation Act (FSA), the local government asked MHW for the application of FSA. Soon after, the chief of the Public Health Bureau replied to the local government that the application of FSA to the Minamata area was impossible. Epidemiological investigations of residents and polluted areas, therefore, were not carried out. Data essential for the screening for exposed residents were unavailable. The criteria for the screening were presented. The Environmental Agency (EA) presented the criteria in the form of notice in 1971, which were revised in 1977. Notwithstanding the clear difference between the original and revised criteria, EA insisted that these two sets of criteria were quite similar. This insistence by EA and the absence of epidemiological data on residents and polluted area resulted in the present confusion about Minamata disease. The application of FSA was stopped by bureaucrats who had no interest in the environmental problems and by several scientists patronized by stakeholders (Chisso, Japanese Association of Chemical Industries, MHW and EA). Stakeholders suppressed science.
