In the early 2015, several cases of patients presenting symptoms of mild fever, rash, conjunctivitis and arthralgia were reported in the northeastern Brazil. Although all patients lived in a dengue endemic area, molecular and serological diagnosis for dengue resulted negative. Chikungunya virus infection was also discarded. Subsequently, Zika virus (ZIKV) was detected by reverse transcription-polymerase chain reaction from the sera of eight patients and the result was confirmed by DNA sequencing. Phylogenetic analysis suggests that the ZIKV identified belongs to the Asian clade. This is the first report of ZIKV infection in Brazil.

Brazil's controversial new Forest Code grants amnesty to illegal deforesters, but creates new mechanisms for forest conservation.

The demographic and epidemiologic transition resulting from aging and the increase of life expectation means an increment related to chronic conditions. The healthcare systems contemporary crisis is characterized by the organization of the focus on fragmented systems turned to the acute conditions care, in spite of the chronic conditions prevalence, and by the hierarchical structure without communication flow among the different health care levels. Brazil health care situation profile is now presenting a triple burden of diseases, due to the concomitant presence of infectious diseases, external causes and chronic diseases. The solution is to restore the consistence between the triple burden of diseases on the health situation and the current system of healthcare practice, with the implantation of health care networks. The conclusion is that there are evidences in the international literature on health care networks that these networks may improve the clinical quality, the sanitation results and the user's satisfaction and the reduction of healthcare systems costs.

OBJECTIVE: To investigate the impact of health-related demographic and socioeconomic factors, as well as the impact of factors associated to social activity and the subjective health evaluation on the functional status of elderly people. METHODS: A cross-sectional multicentric study was conducted in a representative population sample in the city of São Paulo, Brazil, in 1989. Functional status was evaluated using a scale of activities of personal and instrumental daily living. It was studied as a dichotomous variable: absence of dependency - disability/difficulty in none of the activities in contrast with moderate/severe dependency - disability/difficulty in 4 or more activities. Multiple regression analysis was applied to hierarchically clustered factors. RESULTS: Those with the following features were more associated to moderate/severe dependency: illiterate, retired, pensioner, house keeper, living in a rented home, age over 65 years, multigenerational family composition, hospitalization in the last 6 months, mental health screening case, no visiting friends, and having a pessimistic perception of his/her own health when compared to their peers. CONCLUSIONS: The identified features associated to moderate/severe dependency suggest a complex net of causes for the declining functional status. However, one can assume that preventive measures directed to specific factors can benefit these population by improving their well-being.

Malaria is still a major public health problem in Brazil, with approximately 306,000 registered cases in 2009, but it is estimated that in the early 1940s, around six million cases of malaria occurred each year. As a result of the fight against the disease, the number of malaria cases decreased over the years and the smallest numbers of cases to-date were recorded in the 1960s. From the mid-1960s onwards, Brazil underwent a rapid and disorganized settlement process in the Amazon and this migratory movement led to a progressive increase in the number of reported cases. Although the main mosquito vector (Anopheles darlingi) is present in about 80% of the country, currently the incidence of malaria in Brazil is almost exclusively (99,8% of the cases) restricted to the region of the Amazon Basin, where a number of combined factors favors disease transmission and impair the use of standard control procedures. Plasmodium vivax accounts for 83,7% of registered cases, while Plasmodium falciparum is responsible for 16,3% and Plasmodium malariae is seldom observed. Although vivax malaria is thought to cause little mortality, compared to falciparum malaria, it accounts for much of the morbidity and for huge burdens on the prosperity of endemic communities. However, in the last few years a pattern of unusual clinical complications with fatal cases associated with P. vivax have been reported in Brazil and this is a matter of concern for Brazilian malariologists. In addition, the emergence of P. vivax strains resistant to chloroquine in some reports needs to be further investigated. In contrast, asymptomatic infection by P. falciparum and P. vivax has been detected in epidemiological studies in the states of Rondonia and Amazonas, indicating probably a pattern of clinical immunity in both autochthonous and migrant populations. Seropidemiological studies investigating the type of immune responses elicited in naturally-exposed populations to several malaria vaccine candidates in Brazilian populations have also been providing important information on whether immune responses specific to these antigens are generated in natural infections and their immunogenic potential as vaccine candidates. The present difficulties in reducing economic and social risk factors that determine the incidence of malaria in the Amazon Region render impracticable its elimination in the region. As a result, a malaria-integrated control effort--as a joint action on the part of the government and the population--directed towards the elimination or reduction of the risks of death or illness, is the direction adopted by the Brazilian government in the fight against the disease.

OBJECTIVE: Data from household food budget surveys were examined in order to describe the regional and socio-economic distribution of household food availability in Brazil in 2002-2003 and trends from 1974 to 2003. METHODS: The study uses data from the "Pesquisa de Orçamento Familiar 2002-2003" budget survey conducted by the Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estatística) from July 2002 to June 2003, including a national sample of 48,470 households. In each household, during seven consecutive days, all monetary and non-monetary expenses with food and beverages for family consumption were registered. Crude weights of purchased foods were transformed into calories and nutrients with the use of food composition tables. RESULTS: Adequate protein content and a high proportion of animal protein were found in all regions and income strata. These were the most important positive aspects identified in the household food availability in Brazil. On the other hand, all regions and socio-economic strata showed excess calories from sugar and little availability of fruits and vegetables. An excessive proportion of calories came from total and saturated fat in the more economically developed regions and in the urban milieu, as well as among higher-income families. Time-trends in metropolitan areas indicated a decline in the consumption of basic, traditional foods, such as rice and beans; notable increases (up to 400%) in the consumption of processed food items, such as cookies and soft drinks; maintenance of the excessive consumption of sugar; and a continuous increase in total fat and saturated fat content in the diet. CONCLUSIONS: Patterns and trends regarding household food availability in Brazil are consistent with the increasing participation of chronic non-communicable diseases in morbidity and mortality and with the continuous increase in the prevalence of obesity.

BACKGROUND: Leptospirosis has become an urban health problem as slum settlements have expanded worldwide. Efforts to identify interventions for urban leptospirosis have been hampered by the lack of population-based information on Leptospira transmission determinants. The aim of the study was to estimate the prevalence of Leptospira infection and identify risk factors for infection in the urban slum setting. METHODS AND FINDINGS: We performed a community-based survey of 3,171 slum residents from Salvador, Brazil. Leptospira agglutinating antibodies were measured as a marker for prior infection. Poisson regression models evaluated the association between the presence of Leptospira antibodies and environmental attributes obtained from Geographical Information System surveys and indicators of socioeconomic status and exposures for individuals. Overall prevalence of Leptospira antibodies was 15.4% (95% confidence interval [CI], 14.0-16.8). Households of subjects with Leptospira antibodies clustered in squatter areas at the bottom of valleys. The risk of acquiring Leptospira antibodies was associated with household environmental factors such as residence in flood-risk regions with open sewers (prevalence ratio [PR] 1.42, 95% CI 1.14-1.75) and proximity to accumulated refuse (1.43, 1.04-1.88), sighting rats (1.32, 1.10-1.58), and the presence of chickens (1.26, 1.05-1.51). Furthermore, low income and black race (1.25, 1.03-1.50) were independent risk factors. An increase of US$1 per day in per capita household income was associated with an 11% (95% CI 5%-18%) decrease in infection risk. CONCLUSIONS: Deficiencies in the sanitation infrastructure where slum inhabitants reside were found to be environmental sources of Leptospira transmission. Even after controlling for environmental factors, differences in socioeconomic status contributed to the risk of Leptospira infection, indicating that effective prevention of leptospirosis may need to address the social factors that produce unequal health outcomes among slum residents, in addition to improving sanitation.

Paracoccidioidomycosis is a systemic fungal disease occurring in Latin America that is associated with rural environments and agricultural activities. However, the incidence and prevalence of paracoccidiodomycosis is underestimated because of the lack of compulsory notification. If paracoccidiodomycosis is not diagnosed and treated early and adequately, the endemic fungal infection could result in serious sequelae. While the Paracoccidioides brasiliensis ( P. brasiliensis ) complex has been known to be the causal agent of paracoccidiodomycosis, a new species, Paracoccidioides lutzii ( P. lutzii ), has been reported in Rondônia, where the disease has reached epidemic levels, and in the Central West and Pará. Accurate diagnoses and availability of antigens that are reactive with the patients' sera remain significant challenges. Therefore, the present guidelines aims to update the first Brazilian consensus on paracoccidioidomycosis by providing evidence-based recommendations for bedside patient management. This consensus summarizes etiological, ecoepidemiological, molecular epidemiological, and immunopathological data, with emphasis on clinical, microbiological, and serological diagnosis and management of clinical forms and sequelae, as well as in patients with comorbidities and immunosuppression. The consensus also includes discussion of outpatient treatments, severe disease forms, disease prevalence among special populations and resource-poor settings, a brief review of prevention and control measures, current challenges and recommendations.

Almost simultaneously, several studies reported the emergence of novel SARS-CoV-2 lineages characterized by their phylogenetic and genetic distinction (1), (2), (3), (4).….

Arbovirus risk in Brazil Despite the existence of an effective vaccine for yellow fever, there are still almost 80,000 fatalities from this infection each year. Since 2016, there has been a resurgence of cases in Africa and South America—and this at a time when the vaccine is in short supply. The worry is that yellow fever will spread from the forests to the cities, because its vector, Aedes spp. mosquitoes, are globally ubiquitous. Faria et al. integrate genomic, epidemiological, and case distribution data from Brazil to estimate patterns of geographic spread, the risks of virus exposure, and the contributions of rural versus urban transmission (see the Perspective by Barrett). Currently, the yellow fever epidemic in Brazil seems to be driven by infections acquired while visiting forested areas and indicates spillover from susceptible wild primates.

Water was the suspected vehicle of Toxoplasma gondii dissemination in a toxoplasmosis outbreak in Brazil. A case-control study and geographic mapping of cases were performed. T. gondii was isolated directly from the implicated water and genotyped as SAG 2 type I.

Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research .

Tuberculosis continues to be a major public health problem. Although efforts to control the epidemic have reduced mortality and incidence, there are several predisposing factors that should be modified in order to reduce the burden of the disease. This review article will address some of the risk factors associated with tuberculosis infection and active tuberculosis, including diabetes, smoking, alcohol use, and the use of other drugs, all of which can also contribute to poor tuberculosis treatment results. Tuberculosis can also lead to complications in the course and management of other diseases, such as diabetes. It is therefore important to identify these comorbidities in tuberculosis patients in order to ensure adequate management of both conditions.

INTRODUCTION: Health problems may negatively affect the psychological and physical aspects of life, influencing the quality of life of older adults. The objective of this study was to analyze the effects of physical activity on quality of life, anxiety, and depression in the elderly population. METHODS: We performed a cross-sectional study of 200 elderly people of both genders. Subjects were divided into two groups: one with 100 senior citizens engaged in physical activities in a social center for the elderly; and another composed of 100 subjects who lived in the community but were not engaged in physical activities. The instruments used to assess physical activities, quality of life, and anxiety and depression were, respectively: the modified Baecke questionnaire; the 36-Item Short Form Health Survey (SF-36); and the Hospital Anxiety and Depression Scale (HADS). The data were analyzed using the Student's t test, Pearson's r, and analysis of variance (ANOVA), with odds ratio and a 5% significance level (p<0.05). RESULTS: We observed that the active group showed higher scores of physical activity and quality of life. Conversely, the sedentary group revealed higher scores of anxiety and depression. Data assessment revealed a strong correlation between the domains quality of life, level of vitality, and mental health (r=0.77). The prevalence ratio showed that physical activity is a protective factor against anxiety and depression in the elderly. CONCLUSION: The findings suggest a correlation between low levels of physical activity and symptoms of anxiety and depression in the elderly living in the community.

O objetivo do presente artigo é apresentar a Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF), que faz parte da "família" de classificações desenvolvida pela Organização Mundial da Saúde (OMS). São apresentados o histórico e o processo de revisão da classificação anterior - Classificação Internacional de Deficiências, Incapacidades e Desvantagens (CIDID)- que deram origem à atual classificação - CIF. O modelo da CIF substitui o enfoque negativo da deficiência e da incapacidade por uma perspectiva positiva, considerando as atividades que um indivíduo que apresenta alterações de função e/ou da estrutura do corpo pode desempenhar, assim como sua participação social. A funcionalidade e a incapacidade dos indivíduos são determinadas pelo contexto ambiental onde as pessoas vivem. A CIF representa uma mudança de paradigma para se pensar e trabalhar a deficiência e a incapacidade, constituindo um instrumento importante para avaliação das condições de vida e para a promoção de políticas de inclusão social. A classificação vem sendo incorporada e utilizada em diversos setores da saúde e equipes multidisciplinares. No entanto, será mais adequada à medida que for utilizada por um número maior de profissionais, em locais diversos e a partir de pessoas e realidades diferentes.

We report the emergence of leptospirosis-associated severe pulmonary hemorrhagic syndrome (SPHS) in slum communities in Salvador, Brazil. Although active surveillance did not identify SPHS before 2003, 47 cases were identified from 2003 through 2005; the case-fatality rate was 74%. By 2005, SPHS caused 55% of the deaths due to leptospirosis.

BACKGROUND: Malaria was eliminated from southern and southeastern Brazil over 50 years ago. However, an increasing number of autochthonous episodes attributed to Plasmodium vivax have recently been reported from the Atlantic Forest region of Rio de Janeiro state. As the P vivax-like non-human primate malaria parasite species Plasmodium simium is locally enzootic, we performed a molecular epidemiological investigation to determine whether zoonotic malaria transmission is occurring. METHODS: We examined blood samples from patients presenting with signs or symptoms suggestive of malaria as well as from local howler monkeys by microscopy and PCR. Samples were included from individuals if they had a history of travel to or resided in areas within the Rio de Janeiro Atlantic Forest, but not if they had malaria prophylaxis, blood transfusion or tissue or organ transplantation, or had travelled to known malaria endemic areas in the preceding year. Additionally, we developed a molecular assay based on sequencing of the parasite mitochondrial genome to distinguish between P vivax and P simium, and applied this assay to 33 cases from outbreaks that occurred in 2015, and 2016. FINDINGS: A total of 49 autochthonous malaria cases were reported in 2015-16. Most patients were male, with a mean age of 44 years (SD 14·6), and 82% lived in urban areas of Rio de Janeiro state and had visited the Atlantic Forest for leisure or work-related activities. 33 cases were used for mitochondrial DNA sequencing. The assay was successfully performed for 28 samples, and all were shown to be P simium, indicative of zoonotic transmission of this species to human beings in this region. Sequencing of the whole mitochondrial genome of three of these cases showed that P simium is most closely related to P vivax parasites from South America. The malaria outbreaks in this region were caused by P simium, previously considered to be a monkey-specific malaria parasite, related to but distinct from P vivax, and which has never conclusively been shown to infect people before. INTERPRETATION: This unequivocal demonstration of zoonotic transmission, 50 years after the only previous report of P simium in people, leads to the possibility that this parasite has always infected people in this region, but that it has been consistently misdiagnosed as P vivax because of an absence of molecular typing techniques. Thorough screening of local non-human primates and mosquitoes (Anopheline) is required to evaluate the extent of this newly recognised zoonotic threat to public health and malaria elimination in Brazil.

BACKGROUND: In 2006, Brazil began routine immunization of infants <15 wk of age with a single-strain rotavirus vaccine. We evaluated whether the rotavirus vaccination program was associated with declines in childhood diarrhea deaths and hospital admissions by monitoring disease trends before and after vaccine introduction in all five regions of Brazil with varying disease burden and distinct socioeconomic and health indicators. METHODS AND FINDINGS: National data were analyzed with an interrupted time-series analysis that used diarrhea-related mortality or hospitalization rates as the main outcomes. Monthly mortality and admission rates estimated for the years after rotavirus vaccination (2007-2009) were compared with expected rates calculated from pre-vaccine years (2002-2005), adjusting for secular and seasonal trends. During the three years following rotavirus vaccination in Brazil, rates for diarrhea-related mortality and admissions among children <5 y of age were 22% (95% confidence interval 6%-44%) and 17% (95% confidence interval 5%-27%) lower than expected, respectively. A cumulative total of ~1,500 fewer diarrhea deaths and 130,000 fewer admissions were observed among children <5 y during the three years after rotavirus vaccination. The largest reductions in deaths (22%-28%) and admissions (21%-25%) were among children younger than 2 y, who had the highest rates of vaccination. In contrast, lower reductions in deaths (4%) and admissions (7%) were noted among children two years of age and older, who were not age-eligible for vaccination during the study period. CONCLUSIONS: After the introduction of rotavirus vaccination for infants, significant declines for three full years were observed in under-5-y diarrhea-related mortality and hospital admissions for diarrhea in Brazil. The largest reductions in diarrhea-related mortality and hospital admissions for diarrhea were among children younger than 2 y, who were eligible for vaccination as infants, which suggests that the reduced diarrhea burden in this age group was associated with introduction of the rotavirus vaccine. These real-world data are consistent with evidence obtained from clinical trials and strengthen the evidence base for the introduction of rotavirus vaccination as an effective measure for controlling severe and fatal childhood diarrhea.

Introdução: As infecções sexualmente transmissíveis (IST) causam impactos negativos na saúde pública com reflexo na qualidade de vida da pessoa, que não entende ou não tem conhecimento sobre sua saúde. Entre essas, a sífilis, quando não tratada, pode evoluir gravemente. Sobretudo, algumas pessoas infectadas não apresentam sintomatologia e outras não percebem sinais e/ou sintomas. Assim, o teste rápido (TR) possibilita o rastreamento e o diagnóstico precoce da infecção e sua realização oferece parte da prevenção combinada para IST, incentivada pelo Ministério da Saúde. Assim, ações para a disponibilidade desses testes são fundamentais. Objetivo: Descrever a relevância da oferta de teste rápido para sífilis para a população, incentivando sua demanda amplificada. Métodos: A atividade aconteceu em uma praia da região metropolitana em Fortaleza, Ceará, em parceria com um projeto local, que disponibilizou o ambiente para a realização dos TR, sendo o público-alvo as pessoas na praia. Para captar os participantes foi realizada abordagem direta, que informava como aconteceria a testagem e esclarecia dúvidas. Realizou-se a primeira fase do TR, a “pré-testagem”, para coleta de dados do paciente, seguida da execução do teste, em que se coletou uma gota de sangue para a análise. Por fim, ocorreu a pós-testagem, em que foi realizado o aconselhamento para os que tiveram o teste negativo e os que testaram positivo, sendo esse último acompanhado de encaminhamentos adequados para cada indivíduo. Resultados: O interesse do público em realizar os TR foi notável, resultando em um considerável alcance. Ao todo, realizaram-se 53 testes, ocorrendo quatro resultados positivos para sífilis, os quais percebi que necessitavam de uma escuta ativa e qualificada para orientarmos apropriadamente cada situação. Conclusão: Conclui-se que falta divulgação do oferecimento de TR para a população devido a relatos dos participantes, tornando-se necessárias novas estratégias para oferta ampla desse direito, estimulando empoderamento no processo saúde-doença.
