MARA LITe

Information

 

The MARA LITe was first released on a CD-ROM in 2002.

Updates to the CD can be downloaded from the Updates page.

The MARA LITe software

 

The MARA LITe software has three major modules:

1. Prevalence data
2. Maps
3. Population data

 

1. Prevalence data module

 

The prevalence data represent results from malaria prevalence surveys (carried out by different researchers, at different times and locations) that have been collated into one single database by the MARA/ARMA project. Only confirmed blood test results from sub-Saharan Africa were included. The earliest studies are from the beginning of the 20th century. Details on sample size, month of survey, sampling methods, diagnostic methods etc were captured, as far as this information was available. For more details see the Prevalence data and Data collection sections in the MARA/ARMA technical report.

 

The Prevalence data module has three sub-modules:

a) Bibliography

    Details on the sources of published and unpublished data included in the database.
b) Database query

    Find out what data are available and calculate mean prevalence for your region of interest.
c) Prevalence survey design

    Use MARA/ARMA data as baseline to design pre- and post- intervention prevalence surveys.


Please note that certain aspects of the data have not been fully checked, eg mismatches between administrative unit names in the database and in the maps.

 

2. Maps module

 

This module provides maps of currently available MARA/ARMA products:


a) Spatial-statistical malaria prevalence models
b) Seasonality of malaria

    (i)   First and last month of the transmission season(s)
    (ii)  Duration of the season
    (iii) Middle of the transmission season

c) Distribution of endemic malaria
d) Risk of epidemic malaria in the East African Highlands (HIMAL project)
e) Maps of products from other sources

    (i)   Population distribution
    (ii)  Reference maps
        Topographical maps, altitude, rainfall, etc

Maps are launched in MapInfo ProViewer, which is a freeware runtime version of MapInfo.

 

3. Population data module

 

This module provides estimates of

 

a) Total population per administrative unit
   
A continental population distribution map is combined with administrative boundaries
    Calculated totals are projected to the required year using annual population growth figures
b) Populations at risk of malaria
   
The population map is combined with models of malaria distribution
    The number of people at different levels of risk are summarised by administrative unit
 

Quality of population estimates are limited by the accuracy of underlying data:
    Population distribution model
    Annual population growth figures by country
    Malaria distribution models
    The climate and other data used to produce the malaria models
    Geographical accuracy of the administrative boundaries

This poster was released in collaboration with RBM.

 

2. Raster GIS files of malaria models
 

Data grids of the original malaria models, though not used by the MARA LITe software, are provided for the benefit of raster GIS software users.
