About the Event
Undiagnosed Day—isn’t just a day, it’s a movement, a day not about the disease, to create awareness and action for People Living With Undiagnosed Diseases (PLWUD). There are too many people living with questions that remain unanswered.
This day is dedicated to the 350 million People Living With Undiagnosed Diseases (PLWUD) and their families but also for the clinicians, researchers, genetic counsellors and patient organizations working tirelessly to find answers.
