The Zambian Malaria Control Programme with the Roll Back (RBM) partners have developed current National Strategic Plan (NMSP 2006-2011) which focuses on prevention based Integrated Vector Management (IVM) strategy. introduction and implementation of an IVM strategy was planned in accordance World Health Organization (WHO) steps towards namely Introduction Phase, Consolidation Phase Expansion Phase.IVM has created commitment for Legal Regulatory policy review, monitoring, Research a strong...
Although malaria treatment aims primarily to eliminate the asexual blood stages that cause illness, reducing carriage of gametocytes is critical for limiting transmission and spread resistance.Clinical parasitological responses fixed-dose combination sulfadoxine pyrimethamine in patients with uncomplicated falciparum were assessed biannually since implementation this policy 1998 Mpumalanga Province, South Africa.Despite sustained cure rates > 90% (P = .14), duration gametocyte increased from...
Uganda's malaria burden includes the sixth highest number of annual deaths in Africa (10,500) with approximately 16 million cases (2013) and entire population at risk. The President's Malaria Initiative has been supporting control interventions indoor residual spraying (IRS) distribution long-lasting insecticidal nets (LLIN) Uganda since 2007. These are threatened by emerging spreading insecticide resistance, known to exist Ugandan vectors. Pyrethroid insecticides have used agriculture early...
In the past decade, there has been rapid scale-up of insecticide-based malaria vector control in context integrated management (IVM) according to World Health Organization recommendations. Endemic countries have deployed indoor residual spraying (IRS) and long-lasting insecticidal nets as hallmark interventions. This paper discusses successes continued challenges way forward for IRS programme Malawi. The National Malaria Control Programme Malawi, with its efforts implement an approach...
BackgroundIncreasing insecticide costs and constrained malaria budgets could make universal vector control strategies, such as indoor residual spraying (IRS), unsustainable in low-transmission settings. We investigated the effectiveness cost-effectiveness of a reactive, targeted IRS strategy.MethodsThis cluster-randomised, open-label, non-inferiority trial compared with standard practice northeastern South Africa over two seasons (2015–17). In clusters, programme managers conducted annual...

Human forearms treated 1.2 BSC, 0.8 PMD towelette or 0.5 exposed to 200 hungry An....
Namibia has made tremendous gains in malaria control and the epidemiological trend of disease changed significantly over past years. In 2010, country reoriented from objective reducing morbidity mortality to goal achieving elimination by 2020. This manuscript outlines processes undertaken strengthening tactical planning operational frameworks for vector facilitate expeditious Namibia.The information sources this study included all available data accessible archived documentary records on...

Abstract The malaria vector Anopheles arabiensis Patton (Diptera: Culicidae) shows a marked predilection (> 80%) for biting the ankles and feet of human subjects, as revealed by our previous observations at Malahlapanga in Kruger National Park, South Africa. Topical application insect repellent, 15% deet ( N,N ‐diethyl‐3‐methylbenzamide), to reduced overall rate An. 69%. A focal epidemic Albertsnek village (25°33′ S, 31°59′ E) near Mozambique border, following flooding during February...
Abstract. Distribution of biting sites on the human body by malaria vector Anopheles arabiensis Patton (Diptera: Culicidae) was investigated near a source mosquitoes in Kruger National Park, South Africa. Eight adult male volunteers (2 teams × 2 pairs subjects) conducted bait collections while seated camp chairs open‐air, wearing only short trousers (no shirt, socks or shoes). Mosquito during 18.30–22.30 hours five consecutive nights April 1998 yielded total 679 An. females subjects with...
Background: The malaria vector Anopheles merus occurs in the Mpumalanga Province of South Africa. As its contribution to transmission Africa has yet be ascertained, an intensification surveillance is necessary provide baseline information on this species. aim study was therefore map An. breeding sites Ehlanzeni District and assess qualitative trends distribution relative abundance species over a 9-year period. Methods: carried out during period 2005-2014 four high-risk municipalities...
Integrated vector management (IVM) is the recommended approach for controlling some vector-borne diseases (VBD). In face of current challenges to disease control, IVM vital achieve national targets set VBD control. Though global efforts, especially combating malaria, now focus on elimination and eradication, remains useful Uganda which principally still in control phase malaria continuum. This paper outlines processes undertaken consolidate tactical planning implementation frameworks...
The complexity of Anopheles gambiae Giles sensu stricto, a sibling species the A. complex, has been shown by extent chromosomal inversion polymorphisms and more recently, divergence at molecular level. Analysis PCR field population complex from Zambezi Valley area Kanyemba, northern Zimbabwe, showed co-existence three species: arabiensis (90%), (4%), quadriannulatus (6%). Molecular characterization s.s. material revealed sympatric presence two forms S M within sample eight. This is first...
