A Climate-based Distribution Model of Malaria Transmission in Sub-Saharan Africa

Craig, M. H., Snow, R. W., le Sueur, D.
Parasitology Today 15(3), 105-111. (3/1/ 1999)

Malaria remains the single largest threat to child survival in sub-Saharan Africa and warrants long-term investment for control. Previous malaria distribution maps have been vague and arbitrary. Marlies Craig, Bob Snow and David le Sueur here describe a simple numerical approach to defining distribution of malaria transmission, based upon biologica...

A new world malaria map: Plasmodium falciparum endemicity in 2010

Gething, Peter, Patil, Anand, Smith, David, Guerra, Carlos, Elyazar, Iqbal, Johnston, Geoffrey, Tatem, Andrew, Hay, Simon
Malaria Journal 10(1), 378. (2011)

BACKGROUND:Transmission intensity affects almost all aspects of malaria epidemiology and the impact of malaria on human populations. Maps of transmission intensity are necessary to identify populations at different levels of risk and to evaluate objectively options for disease control. To remain relevant operationally, such maps must be updated fre...

A world malaria map: Plasmodium falciparum endemicity in 2007

Hay, S. I., Guerra, C. A., Gething, P. W., Patil, A. P., Tatem, A. J., Noor, A. M., Kabaria, C. W., Manh, B. H. , Elyazar, I. R. F., Brooker, S. , Smith, D. L. , Moyeed, R. A., Snow, R. W.

BACKGROUND: Efficient allocation of resources to intervene against malaria requires a detailed understanding of the contemporary spatial distribution of malaria risk. It is exactly 40 y since the last global map of malaria endemicity was published. This paper describes the generation of a new world map of Plasmodium falciparum malaria endemicity fo...

Assessment of Risk Factors Associated with Malaria Transmission in Tubu Village, Northern Botswana

Chirebvu, Elijah, Chimbari, Moses John, Ngwenya, Barbara Ntombi
Malaria Research and Treatment 2014, 10. (2014)

This study investigated potential risk factors associated with malaria transmission in Tubu village, Okavango subdistrict, a malaria endemic area in northern Botswana. Data was derived from a census questionnaire survey, participatory rural appraisal workshop, field observations, and mosquito surveys. History of malaria episodes was associated with...

Coverage of intermittent preventive treatment and insecticide-treated nets for the control of malaria during pregnancy in sub-Saharan Africa: a synthesis and meta-analysis of national survey data, 2009?11

van Eijk, Anna Maria, Hill, Jenny, Larsen, David A., Webster, Jayne, Steketee, Richard W., Eisele, Thomas P., ter Kuile, Feiko O.
The Lancet Infectious Diseases 13(12), 1029-1042. (2013)

Pregnant women in malaria-endemic countries in sub-Saharan Africa are especially vulnerable to malaria. Recommended prevention strategies include intermittent preventive treatment with two doses of sulfadoxine?pyrimethamine and the use of insecticide-treated nets. However, progress with implementation has been slow and the Roll Back Malaria Partner...

Coverage of malaria protection in pregnant women in sub-Saharan Africa: a synthesis and analysis of national survey data

van Eijk, Anna Maria, Hill, Jenny, Alegana, Victor A., Kirui, Viola, Gething, Peter W., ter Kuile, Feiko O., Snow, Robert W.
The Lancet Infectious Diseases 11(3), 190-207. (3// 2011)

Summary Background Insecticide-treated nets and intermittent preventive treatment with sulfadoxine–pyrimethamine are recommended for the control of malaria during pregnancy in endemic areas in Africa, but there has been no analysis of coverage data at a subnational level. We aimed to synthesise data from national surveys about these interventions, ...

Demonstration of successful malaria forecasts for Botswana using an operational seasonal climate model

MacLeod, Dave A, Jones, Anne, Giuseppe, Francesca Di, Caminade, Cyril, Morse, Andrew P
Environmental Research Letters 10(4), 044005. (2015)

The severity and timing of seasonal malaria epidemics is strongly linked with temperature and rainfall. Advance warning of meteorological conditions from seasonal climate models can therefore potentially anticipate unusually strong epidemic events, building resilience and adapting to possible changes in the frequency of such events. Here we present...

Developing a spatial-statistical model and map of historical malaria prevalence in Botswana using a staged variable selection procedure

Craig, Marlies, Sharp, Brian, Mabaso, Musawenkosi, Kleinschmidt, Immo
International Journal of Health Geographics 6(1), 44. (2007)

BACKGROUND:Several malaria risk maps have been developed in recent years, many from the prevalence of infection data collated by the MARA (Mapping Malaria Risk in Africa) project, and using various environmental data sets as predictors. Variable selection is a major obstacle due to analytical problems caused by over-fitting, confounding and non-ind...

Diagnostic allozymes for routine identification of adults of the Anopheles gambiae complex (Diptera, Culicidae)

Mahon, R. J., Green, C. A., Hunt, R. H.
Bulletin of Entomological Research 66(01), 25-31. (1976)

Natural populations of four species of the Anopheles gambiae complex occurring in southern Africa were sampled and individuals identified using ovarian polytene chromosomes (19 species A, 190 species B, 140 species C and 54 A. merus Dön.). The genotypes of these same insects were scored for three loci coding for non-specific esterases, and one locu...

Distribution of African malaria mosquitoes belonging to the Anopheles gambiae complex

Coetzee, M., Craig, M., le Sueur, D.
Parasitol Today 16(2), 74-7. (2000)

The distribution of malaria vector mosquitoes, especially those belonging to species complexes that contain non-vector species, is important for strategic planning of malaria control programmes. Geographical information systems have allowed researchers to visualize distribution data on maps together with environmental parameters, such as rainfall a...
