This article reviews the current status of the use of insecticide-impregnated mosquito nets and other impregnated materials in the Americas. Studies from Brazil, Colombia, Ecuador, Guatemala, Peru, Suriname, and Venezuela are examined. It is concluded that most studies have suffered from experimental design errors, short duration problems, and/or inadequate measurement of health indicators. The...
In this paper, we aim to evaluate the effectiveness of community-based interventions (CBIs) for the prevention and management of malaria. We conducted a systematic review and identified 42 studies for inclusion. Twenty-five of the included studies evaluated the impact of the community-based distribution of insecticide-treated nets (ITNs), indoor residual spraying (IRS), or impregnated bed sheet...
The cost-effectiveness of lambdacyhalothrin-treated nets in comparison with conventional DDT spraying for malaria control among migrant populations was evaluated in a malaria hyperendemic area along the Thai-Myanmar border. Ten hamlets of 243 houses with 948 inhabitants were given only treated nets. Twelve hamlets of 294 houses and 1,315 population were in the DDT area, and another 6 hamlets wi...
The purpose of this study was to investigate the prevalence of bed net use and elucidate the effect of daytime bed net use on preventing dengue hemorrhagic fever (DHF) among children in Vietnam. We conducted a population-based cross-sectional survey and a matched case-control study in Khanh Hoa Province where not only some pre-schoolchildren but also some school children, who take a nap during ...
Mosquito resistance to chemical insecticides is considered a serious threat for the sustainable use of contemporary malaria vector control methods. Fungal entomopathogens show potential as alternative biological control agents against (insecticide-resistant) anophelines. This study was designed to test whether the fungus, Beauveria bassiana, could be delivered to mosquitoes on netting materials...
Background & objectives: Cutaneous leishmaniasis (CL) is an endemic disease in district of Bam. It has created considerable concerns by people and health authorities. The objective of this study was to assess the effect of the earthquake and costs of prevention on CL prevalence after earthquake Methods: This research is based on a natural intervention, in which the information related to the...
Introduction: Anopheles mosquitoes are the sole biologic vectors of mlaria. Up to now, more than 480 species of Anopheles have been identified. The present study was achieved to identify the Anopheles mosquitoes of malaria high risk foci in Hormozgan province (Bashagard and Syahoo districts) and detect their main biologic charactristics in 2007-2008. Methods: Larvae, pupae and adult mosquit...
The degree of effectiveness of mosquito nets against malaria in the Americas has remained uncertain. We carried out a case-control study of net use and mild malaria in the Amazonas state of Colombia. Two hundred ninety cases were enrolled via the Health Department services, and 977 community-based controls matched for age, sex, and place of residence. We found that a large proportion of the pop...
