Wilhelm Foundation has currently organized eight world congresses for undiagnosed diseases "International Conferences on Rare and Undiagnosed Diseases" in collaboration with Dr. Gahl and the host country's doctors. The next World Congress on the Ninth will take place at the Mayo Clinic in Rochester, Minnesota USA. It is postponed due to current COVID-19 pandemic until spring 2021.
Congress's primary goal is to spread awareness of the Undiagnosed Diseases Program (UDP) and Undiagnosed Diseases Network International (UDNI) to get more specialists to help solve the undiagnosed diseases. Another very important feature of the congresses is that the specialists address one of their unresolved diseases and ask the participants for help in solving the mystery, which is the Wilhelm Foundation's intention with the World Congresses.
