What source of information is used to determine malaria-endemic areas?
Definition of malaria-endemic areas, countries, and donor screening requirements are based on the August 2014 FDA Guidance document:
In accordance with FDA recommendations, the CDC's Yellow Book is used to determine malaria-endemic areas depicted on our maps.
What source of information is used to determine vCJD risk areas?
FDA Guidance documents regarding Variant Creutzfeldt-Jakob Disease (vCJD) in blood and blood products are used. The most recent guidance that affects donor screening was published in May 2010:
Why aren't maps included for ALL malaria endemic countries?
Maps are only provided for countries where malaria-endemic areas cover a portion of the country. Maps are not provided for countries that are malaria-endemic in their entirety because
maps are not needed to make deferral determinations for donors that traveled to or resided in one or more of these countries. Therefore there is negligible value in providing maps for such countries, especially compared with the cost of providing them.
Which areas are covered by the additional detail maps?
Afghanistan: Kabul Region
Colombia: Central Highlands region
Guatemala: Guatemala City & Lake Atitlan areas
Indonesia: Bali, Jakarta & the Thousand Islands area, Java, & the Nusa Tenggara region
Malaysia: Kuala Lumpur urban area & Penang State
Mexico: States of Chiapas, & Chihuahua
Philippines: Regions of Mindanao & Palawan
South Korea: Incheon, Kyonggi-do, & Kangwon-do Provinces
Thailand: Southern Region
Vietnam: Mekong Delta & Red River Delta regions
The Caribbean Islands
Why don't all of the maps have overlays in the Reference Editions?
Overlays are created for maps in select cases when geographic disease risk areas are described in terms of administrative divisions (states, provinces, departments, districts, etc.) of a country. Overlays allow users to verify that the risk areas against the administrative division boundaries.
What source of information is used to determine geographic areas?
Maps and other available resources are used to depict each country, location, name, and boundary. Multiple sources are used in the production of each map in order to ensure that the information portrayed is as current and accurate as possible. Sources used in the collection include country and regional maps produced by the United Nations' Cartographic Section of the Department of Field Support, the Food and Agriculture Organization of the United Nations, the United Nations Environment Programme, the United States' National Aeronautic Space Administrations, the Geonames geographic database, and others.
Beginning in 2016, all new and revised maps have been produced using ARCMap GIS software and geographic sources are attributed on each map.
Why aren't maps included for EVERY country in the world?
Just as there is negligible value in providing maps for countries that are malaria-endemic in their entirety (see question to the left), there isn't really any value in providing maps of countries without disease risk either.
If a potential donor reports travel to a country that does not have disease risk, it is not necessary to determine where the donor traveled within the country in order to assess the donor's eligibility.
Some blood banks require verification of non-malaria-endemic countries reported by donors to positively validate that the location reported is actually a country. We include a List of Non-Malaria-Endemic Countries for this purpose.
