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 comparison of Anopheles gambiae and Plasmodium falciparum genetic structure over space and time

Prugnolle, F., Durand, P., Jacob, K., Razakandrainibe, F., Arnathau, C., Villarreal, D., Rousset, F., de Meeus, T., Renaud, F.
Microbes Infect. (Jan 12 2008)

Population genetic structure and subdivision are key factors affecting the evolution of organisms. In this study, we analysed and compared the population genetic structure of the malaria parasite Plasmodium falciparum and its mosquito vector Anopheles gambiae over space and time in the Nianza Province, near Victoria Lake in Kenya. The parasites wer...

A geographic information system applied to a malaria field study in western Kenya

The American Journal of Tropical Medicine and Hygiene 58(3), 266-72. (1998-03)

This paper describes use of the global positioning system (GPS) in differential mode (DGPS) to obtain highly accurate longitudes, latitudes, and altitudes of 1,169 houses, 15 schools, 40 churches, four health care centers, 48 major mosquito breeding sites, 10 borehole wells, seven shopping areas, major roads, streams, the shore of Lake Victoria, an...

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...

African Dominant Vector Species Bionomic Information

A bionomics data set compiled for VecNet by the Malaria Atlas Project (MAP). These data are the result of a three year abstraction process examining published locational and species-specific studies, and through personal contact with researchers and study authors, to provide spatially explicit evidence-based measures of key bionomic variables pert...

Analysis of genetic variability in Anopheles arabiensis and Anopheles gambiae using microsatellite loci

Kamau, L, Mukabana, WR, Hawley, WA, Lehmann, T, Irungu, LW, Orago, AA, Collins, FH
Insect Molecular Biology 8(2), 287-97. (1999)

We analysed genetic variability in Anopheles arabiensis and Anopheles gambiae populations using microsatellite loci to determine whether the Rift Valley restricts the flow of genes. Deviations from Hardy-Weinberg expectations were significant, and were most likely to be due to the high frequency of null alleles observed. An. arabiensis populations ...

Anopheles gambiae complex egg-stage survival in dry soil from larval development sites in western Kenya

Beier, J. C., Copeland, R., Oyaro, C., Masinya, A., Odago, W. O., Oduor, S., Koech, D. K., Roberts, C. R.
J Am Mosq Control Assoc 6(1), 105-9. (1990)

The potential for Anopheles egg survival in dry soil from larval development sites was investigated in western Kenya. A total of 230 dry soil samples collected in 1987, 1988 and 1989 yielded 126 first-instar Anopheles gambiae s.l. larvae from 2 to 5 days after flooding with water. These larvae were from dried animal hoofprints along streams (57.9%)...

Antibody responses to repetitive epitopes of the circumsporozoite protein, liver stage antigen-1, and merozoite surface protein-2 in infants residing in a Plasmodium falciparum-hyperendemic area of western Kenya. XIII. Asembo Bay Cohort Project

Zhou, Z, Xiao, L, Branch, OH, Kariuki, S, Nahlen, BL, Lal, AA
The American Journal of Tropical Medicine and Hygiene 66(1), 7-12. (2002-01-1)

The present study was initiated to characterize antibody responses to repetitive epitopes of the circumsporozoite protein (CSP), liver stage antigen-1 (LSA-1), and merozoite surface protein-2 (MSP-2) of Plasmodium falciparum in infants residing in a P. falciparum-hyperendemic area of western Kenya. In this study, development and maintenance of thes...
