Entre 2008 e 2014 foi realizado um estudo de intervenção tipo ensaios de campo (comunitário) de nível agregado com o fim de desenvolver uma estratégia de controle integrado da malária no rio Padauiri, médio rio Negro, estado de Amazonas, uma área altamente endêmica com presença de infecção assintomática por Plasmodium. Uma área que não foi objeto da intervenção foi usada como controle. Foram acompanhadas 208 pessoas. Após um estudo de linha de base foram desenvolvidas as seguintes atividades: 1) Estratégia educativa dirigida às crianças e adultos sobre conhecimentos básicos em malária enfatizando nos determinantes de risco e formas de prevenção 2) Distribuição e avaliação do uso dos mosquiteiros impregnados. No estudo de linha de base foi encontrado que 98,6% dos indivíduos tiveram pelo menos um episódio prévio da doença mas só 13,1% tinham conhecimentos sobre formas de prevenção. Cinco anos após a intervenção 60,49% dos indivíduos deram respostas corretas sobre as formas de prevenção enquanto que só 23,64% do controle tinham esses conhecimentos claros. No estudo de linha de base, foi encontrado que 9,9% dos indivíduos do grupo de intervenção haviam dormido com mosquiteiro na noite anterior contra 37,8% do controle. Já em 2010, este percentual foi de 43,2% no grupo de intervenção contra 50,9% no controle. Assim, um ano após a implementação da estratégia, os mosquiteiros foram mais utilizados em ambos os grupos e este aumento no uso foi maior no grupo de intervenção (p=0,000004), mas não no controle (p=0,138); passados cinco anos após a implementação, o uso dos MILDs reduziu em 28,3% no grupo de intervenção e 20,1% no grupo controle. Quando verificado se haviam MILDs suficientes para todos os membros da família, no grupo de intervenção 76% dos domicílios possuíam MILDs suficientes contra 50% do controle (p=0,007). Comparando o acesso com o uso, vimos que a pesar de 85,1% dos indivíduos do grupo de intervenção terem acesso a um MILD, apenas 14,9% fizeram uso deste na noite anterior; isto também aconteceu com o controle, no qual 63,8% tinham acesso, mas apenas 30,8% utilizaram-no. Houve uma alta propriedade e retenção dos MILDs no grupo de intervenção. Um ano após a distribuição desses MILDs houve um aumento significativo de seu uso que não foi mantido ao longo prazo; concluímos que as estratégias de controle devem ser permanentes e que é preciso a busca de novas estratégias para que os conhecimentos adquiridos se convertam em modificação de atitudes e comportamentos.

Between 2008 and 2014 we conducted a study of intervention type field trials (community) aggregate level in order to develop a strategy for the integrated control of malaria in the Padauiri River, Middle rio Negro, Amazonas State, a highly endemic area with presence of asymptomatic infection by Plasmodium. An area that has not been object of intervention was used as control. Were accompanied by 208 people. After a baseline study were developed the following activities: 1) educational Strategy aimed at children and adults about basic knowledge on malaria emphasizing risk determinants and forms us in prevention 2) distribution and evaluation of the use of impregnated mosquito nets. In the baseline study was found that 98.6% of individuals had at least one prior episode of the disease but only 13.1% had knowledge of forms of prevention. Five years after the intervention 60.49% of individuals have given correct answers on the forms of prevention while only 23.64% of the control they had this knowledge. In the baseline study, it was found that 9.9% of the intervention group subjects had been sleeping with mosquito net the night before against 37.8% of the control. Already in 2010, this percentage was 43.2% in the intervention group versus 50.9% in the control. So, one year after the implementation of the strategy, the nets were used in both groups and this increase in use was greater in the intervention group (p = 0.000004), but not in the control (p = 0.138); After five years of implementation, the use of MILDs reduced in intervention group 28.3% and 20.1% in the control group. When checked if there were enough MILDs for all family members, in the intervention group, 76% of households possessed sufficient MILDs against 50% of control (p = 0.007). Comparing access using, we saw that in spite of 85.1% of the intervention group subjects to have access to a MILD, only 14.9% made use of this the night before; This also happened with the control, in which 63.8% had access, but only 30.8% used on a high ownership and retention of MILDs in the intervention group. A year after the distribution of these MILDs there was a significant increase of its use that has not been kept long term; We conclude that control strategies must be permanent and that it is necessary to search for new strategies so that the knowledge gained into modification of attitudes and behaviours.

There was a high property and retention of LLINs in the intervention group. One year after the distribution of LLINs there was a significant increase in its use that was not maintained over time; we conclude that control strategies must be permanent and what it takes to search for new strategies so that the knowledge gained from becoming modification of attitudes and behaviors.

Between 2008 and 2014, a study was conducted of intervention type field trials (community) of aggregate level in order to develop a strategy of integrated control of malaria in the river padauiri, medium, black river, state of Amazonas, a highly endemic area with the presence of asymptomatic infection by Plasmodium. An area that has not been the object of intervention was used as a control.They were accompanied by 208 people. After a study of base line were developed in the following activities: 1) educational strategy aimed at children and adults on basic knowledge, emphasizing on malaria risk determinants and ways of prevention 2) distribution and evaluation of the use of impregnated mosquito nets. In the study of baseline was found that 98,6% of subjects had at least one prior episode of disease but only 13.1% had the knowledge about ways of prevention. Five years after the intervention 60,49% of subjects gave correct answers about the forms of prevention, while only 23,64% of control they had clear knowledge. In the study of base line, it was found that 9.9% of subjects in the intervention group had slept with mosquito net on the previous evening against 37.8% of the control. In 2010, this percentage was 43.2% in the intervention group versus 50.9% in the control. Thus, one year after the implementation of the strategy, the nets were used in both groups, and this increase in use was higher in the intervention group (P = 000000 4)But not in control (P = 0138); five years after implementation, the use of Milds decreased by 28.3% in the intervention group and 20.1% in the control group. When checked had Milds sufficient for all members of the family, in the intervention group 76% of households have sufficient Milds against 50% of control (P = 0.007). By comparing the access with the use, we have seen that weigh 85.1% of subjects in the intervention group have access to a mild, only 14.9% made use of the night before. This also happened with the control, in which 63.8% had access to, but only 30.8% used it. There was a high property and retention of Milds in intervention group.A year after the distribution of these Milds there was a significant increase of its use was not maintained over time; we conclude that the control strategies must be permanent and that we need to search for new strategies for the knowledge become the change of attitudes and behaviors.
