Use of maps in the GDRI

Some countries have regional infection risks that do not apply to the whole country. Where appropriate, maps are provided to assist staff in assessing whether a donor has travelled to a risk area. The majority of maps in the GDRI relate to malaria risk. Maps may also be provided for tropical virus or West Nile Virus outbreaks in Europe.

When using maps in the GDRI:

  • Apply the GDRI guidance for all infection risks - only use the map for the named infection risk(s) associated with that map.
     
  • Always use the text of the GDRI as the main source to make decisions. This will include guidance on how to interpret any map that has been provided.
     
  • Malaria maps may present information about neighbouring countries but this should not be used for malarial assessment.

The colours used in the malaria maps are presented below.

Colour Sample Text Action
Red High risk Apply Malaria Donor Selection Guideline
Dark pink/ hatched Variable risk/low risk Apply Malaria Donor Selection Guideline
Light pink Low to no risk Can donate
Yellow Surrounding country with malaria risk Do not use for malaria assessment
Green (Surrounding country with no malaria risk) Do not use for malaria assessment
