Resumo: ABSTRACT OBJECTIVE To assess the ownership and use of mosquito nets in 2014, in Mozambique. METHODS This observational and cross-sectional study assessed, in February and March 2015, 69 districts (nine of 11 provinces of Mozambique) that have benefited from the mass distribution of mosquito nets. The Lot Quality Assurance Sampling methodology was used. Each locality was denominated supervision area. The Lot Quality Assurance Sampling opts for a minimum of 19 households (in this case, we decided for a minimum of 100 households per district) from each supervision area to assess an indicator (in this case, two indicators were assessed: ownership and use of mosquito nets). Two questions guided the research: a) received a mosquito net; b) used a mosquito net the night before. RESULTS A total of 6,725 households were assessed. Eighty three percent of them had received mosquito nets in the campaign. Of the 6,232 respondents, 82.0% said they used mosquito nets the night before. The districts of the provinces with low coverage of ownership and use were Tete (69.5% and 60.0%, respectively), Zambezia (79.0% and 60.0%, respectively), and Gaza (81.6% and 70.7%, respectively). The largest coverage of ownership and use were observed in the districts of Nampula (96.7% and 93.8%, respectively) and Niassa (86.0% and 85.4% respectively). CONCLUSIONS In the districts assessed, the progression of ownership and use of mosquito nets is satisfactory. Nampula and Niassa are the only provinces where ownership and use are at desired levels.

RESUMO OBJECTIVO Avaliar a posse e o uso das redes mosquiteiras no ano de 2014 em Moçambique. MÉTODOS Este estudo observacional transversal avaliou, em fevereiro e março de 2015, 68 distritos (nove das 11 províncias de Moçambique) que se beneficiaram da distribuição de redes em massa. Usou-se a metodologia Lot Quality Assurance Sampling. Cada localidade foi designada de área de supervisão. O Lot Quality Assurance Sampling opta por um mínimo de 19 agregados familiares (neste caso decidiu-se um mínimo de 100 agregados familiares por distrito) de cada área de supervisão, a fim de avaliar um indicador (neste caso dois indicadores foram avaliados: posse e uso de redes mosquiteiras). Duas perguntas nortearam a pesquisa: a) recebeu rede; b) usou rede na noite anterior. RESULTADOS Foram avaliados 6.725 agregados familiares . Desses, 83,0% tinham recebido redes na campanha. Dos 6.232 inqueridos, 82,0% disseram que usaram na noite anterior. As províncias com distritos com menores coberturas de posse e uso foram Tete (69,5% e 60,0%, respectivamente), Zambézia (79,0% e 60,0%, respectivamente) e Gaza (81,6% e 70,7%, respectivamente). As maiores coberturas de posse e uso foram observadas nos distritos de Nampula (96,7% e 93,8%, respectivamente) e Niassa (86,0% e 85,4%, respectivamente). CONCLUSÕES Nos distritos avaliados, a progressão para a posse e uso de redes mosquiteiras é satisfatória. Nampula e Niassa são as únicas províncias onde a posse e o uso estão em níveis desejados.

Título: Personal protective measures of pregnant women against Zika virus infection / Medidas de proteção individual de gestantes contra a infecção pelo zika vírus
Fonte: Rev. saúde pública (Online);53:72, 2019. tab.
Idioma: en.
Resumo: ABSTRACT OBJECTIVE To evaluate the adherence of pregnant women to personal protective measures against mosquito bites, recommended by the Ministry of Health, and to investigate the factors associated with the non-adoption of these measures. METHODS We interviewed 177 pregnant women between November 2016 and February 2017 in the 10 basic health units of the municipality of Propriá, state of Sergipe, two located in the rural area and eight in the urban area, during prenatal appointments, to raise information about the use of preventive measures against the vector transmission of Zika virus. Data were analyzed using descriptive statistical methods, chi-square test or Fisher's exact test, and the odds ratio was calculated. The independent variables were grouped by the analysis of principal components, and the dependents (the use of repellent, mosquito nets, garments, screens and insecticides) were analyzed using the logistic regression method. RESULTS Among the measures recommended by the Ministry of Health, mosquito nets were the most used by pregnant women living in rural areas and with low education level, while the repellents were more used by women in the urban area and with higher education level. Women in a vulnerable socio-economic situation presented a risk 2.4 times higher for not using screens in their homes, 1.9 times higher for not changing clothes and 2.5 times higher for not using repellent than pregnant women in better economic conditions. CONCLUSIONS The socioeconomic status of pregnant women, especially among the less privileged, influenced the use of protective measures against Zika virus, from the purchase of repellent, clothing, insecticides to other resources in the municipality of Propriá, SE.

RESUMO OBJETIVO Avaliar a adesão de gestantes às medidas de proteção individual contra picadas de mosquitos, recomendadas pelo Ministério da Saúde e investigar os fatores associados à não adoção dessas medidas. MÉTODOS Foram entrevistadas 177 gestantes entre novembro de 2016 e fevereiro de 2017 nas 10 unidades básicas de saúde da cidade de Propriá, SE, duas localizadas na zona rural e oito na zona urbana, durante as consultas de pré-natal, para levantar informações sobre o uso de medidas preventivas contra a transmissão vetorial do zika vírus. Os dados foram analisados utilizando métodos de estatística descritiva, teste do qui-quadrado ou teste exato de Fisher, e foi calculado o odds ratio . As variáveis independentes foram agrupadas por meio da análise de componentes principais, e as dependentes (uso de repelentes, mosquiteiros, vestimentas, telas e inseticidas) foram analisadas pelo método de regressão logística. RESULTADOS Entre as medidas recomendadas pelo Ministério da Saúde, o uso de mosquiteiros foi a mais utilizada por gestantes residentes na zona rural e de baixa escolaridade, enquanto os repelentes foram mais utilizados por mulheres da zona urbana e com maior tempo de estudo. Mulheres com situação socioeconômica vulnerável apresentaram risco 2,4 vezes maior de não utilizar telas em suas residências, 1,9 vezes maior de não mudar o modo de se vestir e 2,5 vezes maior de não usar repelentes do que gestantes em melhores condições econômicas. CONCLUSÕES A condição socioeconômica das gestantes, especialmente entre as mulheres menos favorecidas, influenciou o uso das medidas de proteção contra o zika vírus, desde a compra de repelentes, vestimentas, inseticidas até outros recursos na cidade de Propriá, SE.

Título: Cost of intensive routine control and incremental cost of insecticide-treated curtain deployment in a setting with low Aedes aegypti infestation
Fonte: Rev. Soc. Bras. Med. Trop;49(4):418-424, July-Aug. 2016. tab.
Idioma: en.
Resumo: Abstract: INTRODUCTION Information regarding the cost of implementing insecticide-treated curtains (ITCs) is scarce. Therefore, we evaluated the ITC implementation cost, in addition to the costs of intensive conventional routine activities of the Aedes control program in the city of Guantanamo, Cuba. METHODS A cost-analysis study was conducted from the perspective of the Aedes control program, nested in an ITC effectiveness trial, during 2009-2010. Data for this study were obtained from bookkeeping records and activity registers of the Provincial Aedes Control Programme Unit and the account records of the ITC trial. RESULTS The annual cost of the routine Aedes control program activities was US$16.80 per household (p.h). Among 3,015 households, 6,714 ITCs were distributed. The total average cost per ITC distributed was US$3.42, and 74.3% of this cost was attributed to the cost of purchasing the ITCs. The annualized costs p.h. of ITC implementation was US$3.80. The additional annualized cost for deploying ITCs represented 19% and 48.4% of the total cost of the routine Aedes control and adult-stage Aedes control programs, respectively. The trial did not lead to further reductions in the already relatively low Aedes infestation levels. CONCLUSIONS At current curtain prices, ITC deployment can hardly be considered an efficient option in Guantanamo and other comparable environments.

Título: The behaviour of mosquitoes in relation to humans under holed bednets: the evidence from experimental huts
Fonte: Mem. Inst. Oswaldo Cruz;109(7):905-911, 11/2014. tab, graf.
Idioma: en.
Resumo: The physical integrity of bednets is a concern of national malaria control programs, as it is a key factor in determining the rate of replacement of bednets. It is largely assumed that increased numbers of holes will result in a loss of protection of sleepers from potentially infective bites. Experimental hut studies are valuable in understanding mosquito behaviour indoors, particularly as it relates to blood feeding and mortality. This review summarises findings from experimental hut studies, focusing on two issues: (i) the effect of different numbers or sizes of holes in bednets and (ii) feeding behaviour and mortality with holed nets as compared with unholed nets. As might be expected, increasing numbers and area of holes resulted in increased blood feeding by mosquitoes on sleepers. However, the presence of holes did not generally have a large effect on the mortality of mosquitoes. Successfully entering a holed mosquito net does not necessarily mean that mosquitoes spend less time in contact with the net, which could explain the lack in differences in mortality. Further behavioural studies are necessary to understand mosquito behaviour around nets and the importance of holed nets on malaria transmission.

Título: Knowledge, attitudes and practices regarding dengue infection in Westmoreland, Jamaica / Conocimientos, actitudes y prácticas con respecto a la infección de Dengue en Westmoreland, Jamaica
Fonte: West Indian med. j;59(2):139-146, Mar. 2010. tab.
Idioma: en.
Resumo: BACKGROUND: Dengue virus infection causes significant morbidity and mortality in most tropical and sub-tropical countries of the world. Dengue fever is endemic in Jamaica and continues to be a public health concern. There is a paucity of information on knowledge, attitudes and practices (KAP) of Jamaicans regarding dengue infection. OBJECTIVE: To describe dengue-related knowledge, attitudes and practices (KAP) of residents of Westmoreland, Jamaica. METHODS: A cross-sectional questionnaire survey of 192 parents attending child health clinics in the Parish of Westmoreland was conducted. RESULTS: More than half of the parents (54%) had good knowledge about signs, symptoms and mode of transmission of dengue. Approximately 47% considered dengue to be a serious but preventable disease to which they are vulnerable. Nevertheless, a majority (77%) did not use effective dengue preventive methods such as screening of homes and 51% did not use bed nets. Educational attainment (OR, 2.98; CI, 1.23, 7.23) was positively associated with knowledge of dengue. There was no correlation between knowledge about dengue and preventive practices (p = 0.34). Radio and TV were the predominant sources of information about dengue fever. CONCLUSION: Findings suggest that the good knowledge about dengue fever among residents of Westmoreland did not translate to adoption of preventive measures. Health programme planners and practitioners need to identify and facilitate removal of barriers to behaviour change related to control of dengue fever among the population. Future campaigns should focus on educating and encouraging individuals and families to adopt simple, preventive actions, such as, use of insecticide treated bed nets and screening of homes.

ANTECEDENTES: La infección del virus del dengue causa morbosidad y mortalidad en un grado significativo en los países más tropicales y sub-tropicales del mundo. La fiebre de dengue es endémica en Jamaica y sigue siendo una preocupación para la salud pública. Hay escasez de información sobre el conocimiento, actitudes y prácticas (KAP) de los jamaicanos con respecto a la infección de dengue. OBJETIVO: Describir los conocimientos, actitudes y prácticas (CAP) de los residentes de Westmoreland, Jamaica, en relación con el dengue. MÉTODOS: Se realizó un cuestionario transversal a 192 padres y madres que asisten a las clínicas de salud infantil en la provincia de Westmoreland. RESULTADOS: Más de la mitad de los padres y las madres (54%) poseían un buen conocimiento acerca de los síntomas, señales, y modo de transmisión del dengue. Aproximadamente 47% veían al dengue como una enfermedad seria pero evitable, a la cual eran vulnerables. Sin embargo, una mayoría (77%) no usaba métodos efectivos para la prevención del dengue, tales como el uso de mallas de protección en las casas y el 51% no usaba mosquiteros. El logro educativo (OR, 2.98; CI, 1.23, 7.23) estuvo positivamente asociado con el conocimiento del dengue. No hubo correlación entre el conocimiento sobre el dengue y las prácticas preventivas (p = 0.34). La radio y la televisión fueron las fuentes predominantes de información sobre la fiebre del dengue. CONCLUSIÓN: Los hallazgos sugieren que el buen conocimiento sobre la fiebre del dengue entre los residentes de Westmoreland no se traduce en adopción de medidas preventivas. Los planificadores y médicos generales a cargo de programas de salud necesitan buscar formas de identificar y eliminar las barreras que obstaculizan el cambio de conducta en relación con el control de la fiebre del dengue entre la población. Las campañas futuras deben estar encaminadas a educar y estimular a individuos y familias a fin de que adopten acciones preventivas simples y económicas, tales como el uso de mosquiteros de cama tratados con insecticida y el uso de mallas de protección en las casas.

Resumo: BACKGROUND: Plasmodium infections among school children in Igbo-Eze South Local Government of Enugu State, Nigeria, were studied between July and December 2005. The relationship between the use of malaria control measures and the prevalence of Plasmodium infections was investigated. METHODS: Blood smears were obtained from 1296 school children (ages 4-15 years) from six schools randomly sampled from the study area. Drugs were given to infected children. Epidemiological questionnaires were administered to the children. RESULTS: Out of 1296 school children examined, 270 (20.8%) had Plasmodium falciparum infections. The prevalence of these parasitic infections varied significantly (p < 0.05) among schools, with Central School, Ovoko (30.1% P falciparum) and Community primary school, Itchi (13.9%), having the highest and lowest prevalence rates respectively. Furthermore, the prevalence of P falciparum infections also varied significantly (p < 0.05) among the age groups, with age groups 4 - 6 (35.1%) and 10-12 (14.2%) having the highest and lowest prevalence rates respectively. Males (23.1%) had a significantly higher prevalence rate than females (18.5%). The prevalence of malaria was significantly lower among pupils using preventive measures; 5.9% among pupils using mosquito bed net as against 21.2% among those not using bed nets and 4.6% for pupils living in screened houses as against 24.1% for those not living in screened houses. CONCLUSION: The study revealed that malaria is a major public health problem among pupils in a Nigerian local community. Prevalence rates among pupils varied among location of schools, age and gender. Preventive measures favoured the use of bed nets and living in screened houses.

ANTECEDENTES: Las infecciones por Plasmodium entre escolares de Igbo-Eze del Gobierno Local Sur del Estado de Enugu, Nigeria, fueron objeto de estudio entre julio y diciembre del 2005. Se investigó la relación entre la aplicación de medidas de control de la malaria y la prevalencia de infecciones por Plasmodium. MÉTODOS: Se obtuvieron frotis sanguíneos de 1296 escolares (4-15 años de edad) de seis escuelas, escogidas de manera aleatoria en el área de estudio. Se le dio medicamentos a los niños infectados. Se administraron encuestas epidemiológicas a los niños. RESULTADOS: De 1296 escolares examinados, 270 (20.8%) estaban infectados por Plasmodium falciparum. La prevalencia de estas infecciones parasitarias varió significativamente (p < 0.05) entre las escuelas, teniendo la Escuela Central, Ovoko (30.1% P falciparum) y la escuela primaria de la comunidad, Itchi (13.9%), las tasas de prevalencia más altas y más bajas respectivamente. Además, la prevalencia de infecciones por P falciparum también varió significativamente (p < 0.05) entre los grupos etarios, teniendo los grupos de edades 4-6 (35.1%) y 10-12 (14.2%) las tasas de prevalencia más alta y más baja respectivamente. Los varones (23.1%) tuvieron una tasa de prevalencia significativamente más alta que las hembras (18.5%). La prevalencia de malaria fue significativamente más baja entre alumnos que aplicaron medidas preventivas: 5.9% entre alumnos que usaban mosquitero, frente al 21.2% entre aquéllos que no usaban mosquiteros y 4.6% para alumnos que vivían en casas protegidas con malla metálica en las ventanas, frente al 24.1% para aquéllos que no vivían en casas protegidas con malla metálica. CONCLUSIÓN: El estudio reveló que la malaria es uno de los mayores problemas de salud pública entre los alumnos en una comunidad local Nigeriana. Las tasas de prevalencia entre los alumnos varió con el lugar, la edad y el género. Las medidas preventivas favorecieron el uso de mosquiteros en los dormitorios y mallas metálicas en las casas.
