“…In this study, women and children under 10 represent the smaller proportion of cases, since they travel less, tend to stay longer inside home, and can use nets and other forms of prevention against exposure to the vector, keeping themselves more protected 21,39 .…”

“…Regarding gender, malaria focused more frequently on males 1,21,34,39 , and aged 15 to 49 years old 6,8,25,30,35 , possibly attributed to the mobility, type of occupation and/or environment in which they reside. This increased participation of males and working age individuals expresses the relocation of labor in the search for employment in areas of greatest risk of transmission, where activities related to agriculture usually prevail, like livestock, hunting/fishing, mining and agricultural exploitation 4,7,14,24,28,31 .…”

SUMMARYThis study describes the epidemiological profile of malaria in the State of Tocantins, in the period [2003][2004][2005][2006][2007][2008], investigates the association between the frequency of malaria and population growth, classifies the cases by 'autochthonous' and 'imported', reports the indices of the disease and analyses the distribution of the cases by Plasmodium species, age and gender. The retrospective study was based on secondary data, stored in SIVEP-malaria and analyzed using the software Epi-Info 3.5.1. and Bioestat 5.0. 19,004 samples were investigated for malaria, 19% of them were positive, 73.32% with Plasmodium vivax, 21.80% with Plasmodium falciparum, 4.79% with mixed infections and only 0.08% with Plasmodium malariae. Male individuals accounted for 76.95% and predominated in all years and age groups, especially in the 15 to 49 years old group. From the overall cases, 34.27% were autochthonous and 65.73% were imported (χ 2 = 356.8, p = 0.0001). The frequency of malaria decreased significantly during the entire series (rp = 0.96, p = 0.002) and the number of municipalities with autochthonous transmission also diminished. It was found that malaria is predominantly imported, related to land activities, which confirms the need for effective measures to maintain vigilance throughout the state and enhance educational activities in order to guide the population towards early treatment-seeking.

“…Pouco se sabe sobre os fatores envolvidos na cadeia de transmissão da malária autóctone [31][32][33] no Estado do Rio de Janeiro. A presença de macacos bugios da espécie Alouatta guariba 34 , de Anopheles (Kertesia) cruzi na região de Mata Atlântica do Rio de Janeiro e a presença de malária em indivíduos que entraram em área de mata fechada são fortes indícios de que há circulação de Plasmodium na região 35 .…”

INTRODUçãO RESUMOIntrodução: A letalidade da malária na região extra-amazônica é cerca de 80 vezes maior do que na Amazônia, que concentra 99,8% dos casos do país. Em áreas de transmissão de dengue, como o Rio de Janeiro, o atraso no diagnóstico e tratamento da malária dos pacientes com febre, provenientes de áreas endêmicas de malária, pode ser, entre outros fatores, devido à confusão entre o diagnóstico das duas doenças pelos generalistas da rede de assistência médica. Neste trabalho, apresentamos as consequências do atraso diagnóstico em três pacientes com malária por Plasmodium falciparum; P. malariae e P. vivax, que, após o périplo habitual para tratamento de dengue, procuraram a nossa instituição onde foram corretamente diagnosticados e submetidos aos tratamentos adequados. Métodos: Descrição de três casos de malária diagnosticada tardiamente e encaminhados ao IPEC/ FIOCRUZ, entre os anos de 2007 e 2008. Resultados: uma brasileira proveniente de Moçambique, primo-infectada por P. falciparum, com malária diagnosticada após 6 dias do início da febre, morreu com malária cerebral e choque. Outro paciente com malária por P. malariae teve um curso grave e prolongado, mas ficou curado após o tratamento específico. A terceira paciente diagnosticada tardiamente apresentou malária por P. vivax adquirida na região de Mata Atlântica no Estado do Rio. Conclusões: Os profissionais de saúde do Rio devem ser treinados para aperfeiçoar a vigilância e o tratamento oportuno da malária e evitar desfechos mórbidos e fatais. Sugere-se que uma investigação de focos de malária autóctone em áreas de mata no estado seja realizada. Palavras-chaves: Malária. Dengue. Diagnóstico diferencial. Vigilância. ABSTRACT Introduction:The mortality of malaria in the extra-Amazon region is about 80 times higher than in the Amazon region, where malaria is concentrated (99.8% of cases). In areas of dengue transmission, delay in the diagnosis and treatment of malaria in patients with fever who reside in areas of malaria transmission can be due to the confusion between the clinical diagnoses of both diseases by nonspecialist doctors, among other factors. This work presents some of the consequences of delayed diagnosis in three patients with malaria by Plasmodium falciparum, P. malariae and P. vivax, who, after following the usual route for Dengue treatment, sought our institution, where they were correctly diagnosed and adequately treated. Methods: Description of three cases of malaria with delayed diagnosed malaria referred to the Outpatient Clinic for Acute Febrile Diseases, IPEC/FIOCRUZ-RJ, between 2007 and 2008. Results: A Brazilian from Mozambique, primo-infected with P. falciparum was diagnosed with malaria six days after the onset of fever and died of cerebral malaria and shock. Another patient with P. malariae malaria presented a severe and prolonged course, but was cured after specific treatment. A third patient, with delayed diagnosis of P. vivax malaria, acquired it in the Atlantic Forest region in the State of Rio. Conclusions: Health pr...

“…Marques et al [33] observed that 75% of infected patients in their study performed some kind of leisure activity and that 25% worked. According to the study conducted by Gil et al [34], malaria cases in the northern and northeastern regions of the State of Rondônia were mainly related to agro-industrial activities.…”

Introduction: Malaria is one of the major parasitic diseases in the State of Rondônia, located in the western Brazilian Amazon. The basic treatment scheme for this disease is chloroquine and primaquine. This study evaluated the epidemiological profile of malaria in Rondônia between 2008 and 2012. Methodology: The epidemiological data were provided by the Health Surveillance Agency from the State of Rondônia, and socioeconomic indicators were obtained from the Brazilian Institute of Geography and Statistics, Department of Informatics of the Unified Health System, and from the National Institute for Space Research. The analyzed variables included year of diagnosis, gender, age group, main activity performed in the 15 days previous to the diagnosis, parasite species, level of parasitemia, number of relapse/recrudescence cases, and socioeconomic and environmental data for Rondônia. Results: A total of 238,626 cases of malaria were recorded in Rondônia during the study period. Of this total, 65.6% were men and the most prevalent age group was 20-39 years. Plasmodium vivax was the most common parasite (89.8%), followed by Plasmodium falciparum (9.4%). An average of 30.9% of the individuals who were tested presented with relapse/recrudescence malaria. The API value was highest in 2008 and lowest in 2012, corresponding to 42.3 cases and 19.2 cases per 1,000 inhabitants, respectively. Conclusions: A 58% reduction in the number of malaria cases and a 36.2% reduction in the number of relapse/recrudescence malaria cases were observed, due to increases in the economy, improvements in the health system, and reduction of deforestation in this region.
