Abstract Background Sub-Saharan Africa harbors the majority of the global burden of malaria and schistosomiasis infections.

PLOS 16/10/14 Impact of Schistosoma mansoni on Malaria Transmission in Sub-Saharan Africa

The co-endemicity of these two tropical diseases has prompted investigation into the mechanisms of coinfection, particularly the competing immunological responses associated with each disease. Epidemiological studies have shown that infection with Schistosoma mansoni is associated with a greater malaria incidence among school-age children. Methodology We developed a co-epidemic model of malaria and S. mansoni transmission dynamics which takes into account key epidemiological interaction between the two diseases in terms of elevated malaria incidence among individuals with S. mansoni high egg output. Principal Findings Conclusions/Significance. MALARIA JOURNAL 08/04/16 Malaria vector populations across ecological zones in Guinea Conakry and Mali, West Africa.

Takan (N 11.47, W 8.33) and Toumani Oulena (N 10.83, W 7.81) are both small villages in the Yanfolila district of southern Mali and represent the Sudanian savannah ecological zone. Takan is arid savannah, while Toumani Oulena is humid savannah. In Guinea Conakry, we sampled in Koraboh, (N 9.28, W 10.03) a small village in the Kissidougou district in the Faranah region representing a semi-forest site with intermediate ecology, a mix of savannah and forest, and in Koundara, (N 8.48, W 9.53), a small village in the Macenta district in the Zezekore region representing deep forest ecology.

European Journal of Business and Management - 2011 - Economic Burden of Malaria in six Countries of Africa

In September 2001, the authors convened a workshop at which a framework for the assessment of the economic burden of malaria in the African region was presented to health economists from 10 countries of the region. The framework document proposes the use of any one of three approaches – production function, cost of illness and willingness to pay – for the assessment of the burden of malaria to the economies of African countries.

Between 2002 and 2005, six countries (Chad, Ghana, Mali, Nigeria, Rwanda and Uganda) undertook studies to assess the economic burden of malaria using the framework. The objective of this article is to report on the methodology, results and policy implications of the country economic burden studies.

LONDON SCHOOL OF HYGIENE & TROPICAL MEDICINE 29/08/13 Targeting mosquito breeding sites could boost malaria control efforts in A. A malaria control method that targets mosquito larvae and pupae as they mature in standing water could be an important supplementary measure in the fight against the disease, according to a new report.

LONDON SCHOOL OF HYGIENE & TROPICAL MEDICINE 29/08/13 Targeting mosquito breeding sites could boost malaria control efforts in A

The Cochrane review – led by the London School of Hygiene & Tropical Medicine in collaboration with Durham University and other researchers in the UK and US – is the first systematic review looking at using larval source management (LSM) to control malaria, which causes an estimated 660,000 deaths worldwide every year. It found evidence that the method may significantly reduce both the number of cases of malaria by up to 75%, and the proportion of people infected with the malaria parasite by up to 90% when used in appropriate settings. LSM is a method that targets immature mosquitoes, found in standing water, before the females develop into flying adults that are capable of transmitting malaria.

I. Efe*, C. O. PLOS 18/07/13 Landscape Movements of Anopheles gambiae Malaria Vector Mosquitoes in Rural Gambia. Background For malaria control in Africa it is crucial to characterise the dispersal of its most efficient vector, Anopheles gambiae, in order to target interventions and assess their impact spatially.

PLOS 18/07/13 Landscape Movements of Anopheles gambiae Malaria Vector Mosquitoes in Rural Gambia

Our study is, we believe, the first to present a statistical model of dispersal probability against distance from breeding habitat to human settlements for this important disease vector. Methods/Principal Findings We undertook post-hoc analyses of mosquito catches made in The Gambia to derive statistical dispersal functions for An. gambiae sensu lato collected in 48 villages at varying distances to alluvial larval habitat along the River Gambia. The proportion dispersing declined exponentially with distance, and we estimated that 90% of movements were within 1.7 km. Conclusions/Significance Our results provide an important quantification of the probability of An. gambiae s.l. dispersal in a rural African setting typical of many parts of the continent.

We sampled An. gambiae sensu lato (sl) between 2008 and 2010 in the Central Highlands of Madagascar at altitudes over 1,200 m. The study site consists of rainforest, rainforest edge, and an open savanna biotope. Anopheles gambiae and An. arabiensis, as well as molecular forms of An. gambiae, were identified molecularly. An. gambiae accounted for 26.7% at the edge of the rainforest and 2.3% in the open savanna biotope. One specimen of this species was caught in the forest. Anopheles gambiae sensu lato is a complex of species, including two freshwater species (Anopheles arabiensis and An. gambiae) and a brackish water species (An. merus) in Madagascar (Chauvet 1969, Léong Pock Tsy et al. 2003).

GRIDA - In the Grip of Malaria in Africa

There are currently 3022 graphics available in the database. Urban growth rate in Africa Africa’s urban centres are currently growing at an annual rate that is the fastest compared to other regions. The urban expansion is expected to continue, with cities like Abuja and Ouagadougou expecting very high growth in the next decade, while Cairo, Africa’s largest city, is projected to see a comparatively lower growth rate. 27 Feb 2011 - by Riccardo Pravettoni, UNEP/GRID-Arendal Estimated costs and benefits of restoration projects in different biomes Biodiversity is the basis for any development; it is the natural capital, the stock of natural ecosystems, which provide services for any human activity. PARASITES AND VECTORS DEC 2009 Distribution, host preference and infection rates of malaria vectors in Mauritania. In Mauritania, malaria is a major public health concern in southern and south-eastern regions. In fact, it is clearly on the increase and significantly contributes to the increase in illness and mortality, especially in children under 5 years of age and pregnant women [1].

In spite of this importance, little is known about its vectors. The only published entomological studies date back 40 years [2,3], although limited entomological investigations were conducted during an outbreak of Rift Valley fever in several localities [4]. An. gambiae s.l. and An. funestus appear to be the dominant vectors of malaria. Their limits of distribution throughout the country are however unknown. In total, 647 anopheline specimens belonging to three species were collected. The predominance of An. arabiensis in the Mauritanian context is in agreement with the general distribution of this species in Africa [10]. Parasites & Vectors 2011, 4:232 (13 December 2011) Integrated prevalence mapping of schistosomiasis, soil-transmitted helminthia. Treatment availability and capacity building Uganda's National Control Programme for combating intestinal schistosomiasis and STHs has been active since 2003, and although regular monitoring has occurred at intervals since then, this is the first comprehensive overview of the status of treatment infrastructure and health capacity on the districts adjacent to Lake Victoria.

The results here paint a mixed picture; on the one hand, some villages appear to function well in terms of drug availability, regular training of CMDs and administration of mass treatment. However, there were also locations, such as much of Wakiso district islands, where people were sceptical about the efficacy or need to take PZQ, while in Masaka district there was a noticeable absence of volunteers willing to take on the role of CMD. The reasons given for refusal included the distance between sites and the lack of adequate funding for travel.
