ABSTRACT
This article discusses questions concerning the future of humanity in the face of threats to the health of populations, whose impact has been exacerbated in the course of inequalities in all parts of the world, pari passu with global development in the hegemonized model since last century. The COVID-19 pandemic is a good example that illustrates this dissonance between development and inequalities. Questions were formulated to be debated about the construction of the future of world society, based on the understanding of the evolutionary character of life on the planet vis-à-vis the evils that affect large contingents of the population and represent powerful risks for this evolutionary process. These questions call attention to the discussion around social participation in the definition and control of public policies, as opposed to the hegemony of private interests in the formulation and execution of these policies, both in the scenarios of each country and in the international context.
O artigo discute questões sobre o futuro da humanidade ante as ameaças que rondam a saúde das populações, cujo impacto vem se exacerbando no curso das desigualdades em todas as partes do mundo, pari passu o desenvolvimento global no modelo hegemonizado a partir do século passado. A pandemia de COVID-19 foi tomada como um caso que bem ilustra essa dessintonia entre desenvolvimento e desigualdades. Formulam-se perguntas a serem postas em debate sobre a construção do futuro da sociedade mundial, com base na acepção sobre o caráter evolucional da vida no planeta vis-à-vis os males que acometem grandes contingentes populacionais e representam poderosos riscos para esse processo evolutivo. São indagações que apontam para a discussão em torno da participação social na definição e no controle das políticas públicas, em contrapartida à hegemonia dos interesses privados na formulação e execução dessas políticas, tanto nos cenários de cada país como no contexto internacional.

ABSTRACT
BACKGROUND: Children with congenital Zika syndrome (CZS) have severe damage to the peripheral and central nervous system (CNS), greatly increasing the risk of death. However, there is no information on the sequence of the underlying, intermediate, immediate, and contributing causes of deaths among these children. The aims of this study are describe the sequence of events leading to death of children with CZS up to 36 months of age and their probability of dying from a given cause, 2015 to 2018. METHODS AND FINDINGS: In a population-based study, we linked administrative data on live births, deaths, and cases of children with CZS from the SINASC (Live Birth Information System), the SIM (Mortality Information System), and the RESP (Public Health Event Records), respectively. Confirmed and probable cases of CZS were those that met the criteria established by the Brazilian Ministry of Health. The information on causes of death was collected from death certificates (DCs) using the World Health Organization (WHO) DC template. We estimated proportional mortality (PM%) among children with CZS and among children with non-Zika CNS congenital anomalies (CA) by 36 months of age and proportional mortality ratio by cause (PMRc). A total of 403 children with confirmed and probable CZS who died up to 36 months of age were included in the study; 81.9% were younger than 12 months of age. Multiple congenital malformations not classified elsewhere, and septicemia unspecified, with 18 (PM = 4.5%) and 17 (PM = 4.2%) deaths, respectively, were the most attested underlying causes of death. Unspecified septicemia (29 deaths and PM = 11.2%) and newborn respiratory failure (40 deaths and PM = 12.1%) were, respectively, the predominant intermediate and immediate causes of death. Fetuses and newborns affected by the mother's infectious and parasitic diseases, unspecified cerebral palsy, and unspecified severe protein-caloric malnutrition were the underlying causes with the greatest probability of death in children with CZS (PMRc from 10.0 to 17.0) when compared to the group born with non-Zika CNS anomalies. Among the intermediate and immediate causes of death, pneumonitis due to food or vomiting and unspecified seizures (PMRc = 9.5, each) and unspecified bronchopneumonia (PMRc = 5.0) were notable. As contributing causes, fetus and newborn affected by the mother's infectious and parasitic diseases (PMRc = 7.3), unspecified cerebral palsy, and newborn seizures (PMRc = 4.5, each) were more likely to lead to death in children with CZS than in the comparison group. The main limitations of this study were the use of a secondary database without additional clinical information and potential misclassification of cases and controls. CONCLUSION: The sequence of causes and circumstances involved in the deaths of the children with CZS highlights the greater vulnerability of these children to infectious and respiratory conditions compared to children with abnormalities of the CNS not related to Zika.

BACKGROUND: The clinical manifestations of microcephaly/congenital Zika syndrome (microcephaly/CZS) have harmful consequences on the child's health, increasing vulnerability to childhood morbidity and mortality. This study analyzes the case fatality rate and child-maternal characteristics of cases and deaths related to microcephaly/CZS in Brazil, 2015-2017. METHODS: Population-based study developed by linkage of three information systems. We estimate frequencies of cases, deaths, case fatality rate related to microcephaly/CZS according to child and maternal characteristics and causes of death. Multivariate logistic regression models were applied. RESULTS: The microcephaly/CZS case fatality rate was 10% (95% CI 9.2-10.7). Death related to microcephaly/CZS was associated to moderate (OR = 2.15; 95% CI 1.63-2.83), and very low birth weight (OR = 3.77; 95% CI 2.20-6.46); late preterm births (OR = 1.65; 95% CI 1.21-2.23), Apgar < 7 at 1st (OR = 5.98; 95% CI 4.46-8.02) and 5th minutes (OR = 4.13; 95% CI 2.78-6.13), among others. CONCLUSIONS: A high microcephaly/CZS case fatality rate and important factors associated with deaths related to this syndrome were observed. These results can alert health teams to these problems and increase awareness about the factors that may be associated with worse outcomes.

OBJECTIVE: to describe the geographical distribution of intermediate hosts of Schistosoma mansoni in five Brazilian states. METHODS: this was a descriptive cross-sectional study; municipalities were selected in the states of Paraná (78), Minas Gerais (120), Bahia (82), Pernambuco (51) , and Rio Grande do Norte (98), for the period 2012 to 2014; these municipalities were chosen because they did not have current records of the presence of snails vectores de S. mansoni. The molluscs were captured and taxonomically identified and examined for S. mansoni cercariae. RESULTS: the work was carried out in 427 municipalities (99.5% of the 429 selected); the presence of mollusks was registered in 300 (70.2%) municipalities; Biomphalaria glabrata were found in 62 (21%) municipalities, B. straminea in 181 (60%), B. tenagophila in three (1%); B. glabrata/B. straminea association was found in 53 municipalities (18%) and B. glabrata/B. tenagophila association in one (0.3%) municipality. CONCLUSION: B. glabrata, B. straminea and B. tenagophila distribution records obtained in this study are consistent with previously known distribution.

This article analyses the process of construction of Health Surveillance in Brazil concerning the political, historical and organizational context of this component of the Unified Health System (UHS), by means of its historical view and presentation of the advances, limits, setbacks and perspectives. Throughout trajectory of Health Surveillance, its objects of study and intervention have been expanded, strengthening the integration among the different areas of surveillance, increasing its capacity for prediction and intervention. It evolved from surveillance of people, to surveillance of diseases and now to surveillance of health risks, promoting greater articulation of HS professionals with agents of endemics and Family Health Teams. The first National Health Surveillance Conference, in February 2018, provided opportunities for discussion and formulation of proposals aimed at strengthening HS, expanding its scope of actions with a view to achieving a comprehensive care model. Adequate and audacious alternatives are necessary so that there are no setbacks in the financing modalities in order to maintain and expand the advances achieved in the field of Health Surveillance in Brazil.

This article presents the development of the epidemiological situation of some of the major communicable diseases (CD) in Brazil, with emphasis on the interventions by the SUS and other social policies. The data and information were collected from Datasus, epidemiological newsletters from the Brazilian Ministry of Health, and scientific articles on the issue. The universalization, decentralization and expansion of the surveillance, control and prevention of CD has produced an impact on the morbidity and mortality of these diseases, mainly those which are vaccine-preventable. The emergence and re-emergence of three arboviruses, for which there are no effective control instruments, interrupted the downward trend in the morbidity profile of CD in Brazil. Other social and economic programs, which are geared to the needier sectors of the Brazilian population, have also contributed to the improvement of the analyzed health indicators. However, the universalization of access to healthcare services, as well as improvements in the scope of the surveillance of diseases and health risks, has played a key role in improving the health and quality of life of the population, as well as contributing to the process of the democratization of Brazil.
Apresenta-se a evolução da situação epidemiológica de algumas das principais Doenças transmissíveis (DT) no Brasil, assinalando as intervenções proporcionadas pelo SUS e outras políticas sociais. Dados e informações foram levantados do Datasus e Boletins epidemiológicos do Ministério da Saúde e de artigos científicos sobre o tema. A universalização, a descentralização e a ampliação das ações de vigilância, controle e prevenção de DT produziram impacto sobre a morbimortalidade dessas doenças, principalmente das imunopreveníveis. A emergência e reemergência de três arboviroses, para as quais não se dispõe de instrumentos de controle efetivos, interromperam a evolução decrescente no perfil de morbidade das DT no Brasil. Outros programas sociais e econômicos, voltados para a população brasileira mais carente, também contribuíram para a melhoria dos indicadores de saúde analisados. Contudo, a universalização do acesso aos serviços de atenção à saúde, ao lado do aperfeiçoamento do escopo de atuação da vigilância sobre doenças e riscos à saúde, vem desempenhando papel fundamental na melhoria das condições de saúde e qualidade de vida da população, bem como contribuindo para o processo de democratização do país.

This study aims to analyze the different binational/multinational activities, programs, and structures taking place on the borders of Brazil and the U.S. between 2013 and 2015. A descriptive exploratory study of two border epidemiological surveillance (BES) systems has been performed. Two approaches were used to collect data: i) technical visits to the facilities involved with border surveillance and application of a questionnaire survey; ii) application of an online questionnaire survey. It was identified that, for both surveillance systems, more than 55% of the technicians had realized that the BES and its activities have high priority. Eighty percent of North American and 71% of Brazilian border jurisdictions reported an exchange of information between countries. Less than half of the jurisdictions reported that the necessary tools to carry out information exchange were available. Operational attributes of completeness, feedback, reciprocity, and quality of information were identified as weak or of low quality in both systems. Statements, guidelines, and protocols to develop surveillance activities are available at the U.S.-Mexico border area. The continuous systematic development of surveillance systems at these borders will create more effective actions and responses.

BACKGROUND: On Nov 11, 2015, the Brazilian Ministry of Health declared a Public Health Emergency of National Concern in response to an increased number of microcephaly cases, possibly related to previous Zika virus outbreaks. We describe the course of the dual epidemics of the Zika virus infection during pregnancy and microcephaly in Brazil up to Nov 12, 2016, the first anniversary of this declaration. METHODS: We used secondary data for Zika virus and microcephaly cases obtained through the Brazilian Ministry of Health's surveillance systems from Jan 1, 2015, to Nov 12, 2016. We deemed possible Zika virus infections during pregnancy as all suspected cases of Zika virus disease and all initially suspected, but later discarded, cases of dengue and chikungunya fever. We defined confirmed infection-related microcephaly in liveborn infants as the presence of a head circumference of at least 2 SDs below the mean for their age and sex, accompanied by diagnostic imaging consistent with an infectious cause, or laboratory, clinical, or epidemiological results positive for Zika virus or STORCH (infectious agents known to cause congenital infection, mainly syphilis, toxoplasmosis, cytomegalovirus, and herpes simplex virus). We excluded cases of congenital anomalies or death without microcephaly. We analyse the spatial clustering of these diseases in Brazil to obtain the kernel density estimation. FINDINGS: Two distinct waves of possible Zika virus infection extended across all Brazilian regions in 2015 and 2016. 1â673â272 notified cases were reported, of which 41â473 (2·5%) were in pregnant women. During this period, 1950 cases of infection-related microcephaly were confirmed. Most cases (1373 [70·4%]) occurred in the northeast region after the first wave of Zika virus infection, with peak monthly occurrence estimated at 49·9 cases per 10â000 livebirths. After a major, well documented second wave of Zika virus infection in all regions of Brazil from September, 2015, to September, 2016, occurrence of microcephaly was much lower than that following the first wave of Zika virus infection, reaching epidemic levels in all but the south of Brazil, with estimated monthly peaks varying from 3·2 cases to 15 cases per 10â000 livebirths. INTERPRETATION: The distribution of infection-related microcephaly after Zika virus outbreaks has varied across time and Brazilian regions. Reasons for these apparent differences remain to be elucidated. FUNDING: None.

OBJETIVO: descrever a magnitude das doenças de notificação compulsória (DNC) e avaliar indicadores de vigilância epidemiológica nos 121 municípios da linha de fronteira (MLF) do Brasil. MÉTODOS: estudo descritivo, com dados do Sistema de Informação de Agravos de Notificação (Sinan) referentes ao período de 2007 a 2009, sobre 45 doenças/agravos constantes da lista das DNC e de avaliação normativa de indicadores selecionados de vigilância epidemiológica. RESULTADOS: foram registradas 405.484 notificações, relacionadas a 36 DNC; observaram-se diferenças na magnitude e distribuição de DNC entre os MLF e demais municípios do país, com desempenho heterogêneo dos indicadores de vigilância epidemiológica; no conjunto dos MLF, detectou-se baixa oportunidade de notificação e de encerramento de DNC. CONCLUSÃO: a região de fronteira do país não é uniforme. Do ponto de vista epidemiológico; destacam-se fragilidades nas capacidades das vigilâncias municipais, em especial na detecção e notificação oportuna de doenças com potencial epidêmico e ainda na capacidade de resposta às emergências de Saúde Pública.

MÉTODOS: estudio descriptivo con datos del Sistema de Información de Enfermedades de Declaración Obligatoria (Sinan) referentes a los años 2007-2009, sobre 45 enfermedades que figuran en la lista de DNC y de evaluación normativa de los indicadores de vigilancia epidemiológica. RESULTADOS: se registraron 405.484 notificaciones referentes a 36 DNC; se observaron diferencias en la magnitud y distribución de las DNC, entre los MLF e demás municipios del país, con un desempeño heterogéneo de indicadores de VE entre los MLF; detectamos baja oportunidad de notificación y cierre de DNC. CONCLUSIÓN: a región fronteriza no es uniforme.Del punto de vista epidemiológico; encontramos debilidades en las capacidades de vigilancia municipal, en especial en cuanto a la detección e notificación oportuna de enfermedades con potencial epidémico y en lacapacidad de respuesta oportuna a emergencias de salud pública.
OBJECTIVE: to describe the magnitude and timely reporting of Notifiable Diseases (ND) and evaluate epidemiological indicators in 121 Brazilian border cities. METHODS: this was a descriptive study using Notifiable Diseases Information System (Sinan) 2007-2009 data on 45 diseases notifiable in Brazil, as well as normative evaluation of selected epidemiological surveillance indicators. RESULTS: 405,484 notifications were recorded relating to 36 ND; differences in ND magnitude and distribution were found in border areas in comparison with other Brazilian cities, with heterogeneous performance in the epidemiological surveillance indicators. ND notification and timeliness of case outcome was also poor. CONCLUSION: the country's border area is not uniform. Weaknesses were found in municipal epidemiological surveillance systems, especially in detecting and timely reporting of diseases with epidemic potential, and also in the ability to respond to public health emergencies.

Objetivo: descrever a tendência temporal das hospitalizações por causas relacionadas à influenza e avaliar o impacto da vacinação na população idosa brasileira (=60 anos de idade), no período de 1992 a 2006. Métodos: estudo ecológico com dados do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH/SUS); foi realizada a análise da tendência dos coeficientes de morbidade hospitalar (CMH) por meio de modelos de regressão polinomial. Resultados: constatou-se que no Brasil, o CMH por essas causas diminuiu em média 0,75/1000 idosos/ano (p<0,0001); foram observadas reduções dos CMH nos períodos de maio a agosto, após a introdução das campanhas de vacinação contra a influenza, na maioria das macrorregiões brasileiras; na região Norte, entretanto, o estudo aponta para ausência de redução dos CMH. Conclusão: há evidências de que a vacinação contra a influenza tenha contribuído na prevenção das hospitalizações pelas causas relacionadas à influenza no Brasil, com exceção da região Norte.
Objective: to describe the time trend of hospitalizations owing to influenza-related causes and to assess the impact of vaccination among the Brazilian population aged>60 years between 1992 and 2006. Methods: ecological and observational study using data from the Brazilian National Hospitalization Information System (SIH/SUS). Trend analysis of hospital morbidity rates was performed using polynomial regression models. Results: in Brazil hospital morbidity rates from these causes in the population aged >60 decreased on average by 0.75/1,000 elderly/year (p<0,0001). Hospital morbidity rates were seen to reduce between May and August following the introduction of influenza vaccination campaigns in most regions of Brazil. However, in the northern region the study showed no reduction in hospital morbidity rates. Conclusion: there is evidence that influenza vaccination has contributed to the prevention of hospitalizations for influenza-related causes in Brazil, except in the northern region.

OBJECTIVE: To evaluate Brazil's public health surveillance system (HSS), identifying its core capacities, shortcomings, and limitations in dealing with public health emergencies, within the context of the International Health Regulations (IHR 2005). METHODS: In 2008-2009 an evaluative cross-sectional study was conducted using semistructured questionnaires administered to key informants (municipal, state, and national government officials) to assess Brazilian HSS structure (legal framework and resources) and surveillance and response procedures vis-à-vis compliance with the IHR (2005) requirements for management of public health emergencies of national and international concern. Evaluation criteria included the capacity to detect, assess, notify, investigate, intervene, and communicate. Responses were analyzed separately by level of government (municipal health departments, state health departments, and national Ministry of Health). RESULTS: Overall, at all three levels of government, Brazil's HSS has a well-established legal framework (including the essential technical regulations) and the infrastructure, supplies, materials, and mechanisms required for liaison and coordination. However, there are still some weaknesses at the state level, especially in land border areas and small towns. Professionals in the field need to be more familiar with the IHR 2005 Annex 2 decision tool (designed to increase sensitivity and consistency in the notification process). At the state and municipal level, the capacity to detect, assess, and notify is better than the capacity to investigate, intervene, and communicate. Surveillance activities are conducted 24 hours a day, 7 days a week in 40.7% of states and 35.5% of municipalities. There are shortcomings in organizational activities and methods, and in the process of hiring and training personnel. CONCLUSIONS: In general, the core capacities of Brazil's HSS are well established and fulfill most of the requisites listed in the IHR 2005 with respect to both structure and surveillance and response procedures, particularly at the national and state levels.
