Malaria Atlas Project malaria risk maps
What do these maps show?
They show approximately where malaria is present globally and are not bad as a rough
guide. They are being continually updated as better information on the distribution
of malaria is collected.
Why are some distributions in 'no malaria' areas?
In these cases the white 'no malaria' indication is inaccurate. Our methods are
being improved and these mistakes will diminish as our techniques and information
improve.
How are these maps generated?
The maps show if malaria (either Plasmodium falciparum or Plasmodium vivax) can
be transmitted. To do this we record all areas for which malaria has been reported
to have been transmitted from international travel health guidelines. We then exclude
altitudes above which we know transmission cannot occur and big cities where we
also know transmission is massively diminished. We also exclude very low population
density areas where virtually nobody lives. The scientific publications describing
the assembly and future of these maps can be found
here.
What factors do these maps not take into account?
Many. For example, they do not consider small scale local variations like a river
running through a dry area that would make malaria much more likely. They also do
not consider malaria prevention activities. Importantly they will miss tiny villages
in predominantly low population density areas.
Are better maps being produced and why?
Yes, better maps are being produced because they can help us better understand which
areas are at risk of malaria. Importantly they will also be able to tell us how
much malaria is within these boundaries. This can help those planning and carrying
out action to fight malaria. For further background information visit the
MAP website.
Use of MAP data on Against Malaria sites
The MAP map data has been superimposed on our own maps for purely illustrative purposes.
Any inaccuracies with the maps or the positioning of MAP data is the responsibility
of Against Malaria.
