Maps of Morgellons Research Foundation Registrants in the United States The Morgellons Research Foundation (MRF) has received registrations from people reporting this condition from all fifty U.S. states. The MRF has also received registrations from people reporting this condition from 45 other countries, most notably Canada, Australia, England, South Africa and the Netherlands. U.S. Families Registered Note: The maps below are based on U.S. families who felt that they fit the criteria for Morgellons disease, and were motivated to register with the Morgellons Research Foundation. These are all self-reported cases, and likely do not represent the true number of families affected by this illness. Although this is clearly not a methodical study of an officially defined disease, we feel that the numbers below justify an official, unbiased investigation of this situation. California Families Registered Note: Although California represents 12% of the US population, 24% of all families in the U.S. who have registered with the Morgellons Research Foundation reside in California.
