“…The increase in the percentage of P. falciparum infections observed in this study may be directly related to the delay in implementing the necessary actions to stop outbreaks of transmission 35 , since 74.38% of cases started treatment after 48 hours of onset of first symptoms.…”

“…Moreover, after the suspicion of a case, the deadline for starting the treatment has been effective, on average 90.79% of the cases started treatment within 24 hours of collection of the blood sample. The rate of hospitalization increased from 21% in 2003 to 35 Regarding the origin of imported cases 89.97% come from states that are part of the Amazon, especially the state of Pará, which borders Tocantins and 8.72% are coming from two neighboring countries -Guiana and Suriname; left only 1.31% of the cases arising from other states of Brazil and six other countries (Table 3).…”

“…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.

“…Apesar de a malária ter classicamente maior impacto sobre as populações rurais (16)(17)(18), observa-se, na atualidade, com o intenso êxodo rural de tendência mundial, uma dinâmica de transmissão mais periurbana, em ambiente com boa receptividade, fundamentalmente pela ocupação desordenada, em áreas próximas à floresta tropical, com condições sanitárias e de instrução precárias (6). Situação semelhante pode ser vista na capital do Amazonas, Manaus (19).…”

Objetivo. Descrever as características epidemiológicas da malária e seus principais determinantes no Município de Cruzeiro do Sul, no Estado do Acre, Brasil, entre 1998 Conclusões. O incentivo a atividades econômicas em áreas periurbanas de transmissão instável de malária, típicas da América Latina, deve ser muito bem planejado. O controle da malária em Cruzeiro do Sul baseou-se em estratégias integradas implementadas simultaneamente pelos governos federal, estadual e municipal, como preconizado pelo Plano Nacional de Controle da Malária. É importante ressaltar a utilidade de um bom sistema de informação como o SIVEP-Malária para estimar a carga de doença e monitorar de forma eficiente o impacto das intervenções.Malária; estudos epidemiológicos; incidência; piscicultura; Brasil. RESUMOAtualmente, a malária é a mais incidente doença parasitária do mundo. Estima-se que o número de casos novos a cada ano chegue a 250 milhões, com 880 mil mortes. Aproximadamente metade da população mundial está exposta à infecção, especialmente pessoas que vivem em países pobres (1).Desde que o governo brasileiro se voltou para a organização dos planos de intervenção sanitária na Amazônia, essa

“…The northern region of the State has the municipalities traversed by the Madeira River and its tributaries in addition to a large contingency of streams. The high rates of incidence in this region can be explained by the fact that these streams present favorable conditions for disease maintenance, where the inhabitants are asymptomatic carriers of the parasite [27][28][29].…”

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.
