SUDC UK is dedicated to raising awareness, funding research and helping families affected by Sudden Unexplained Death in Childhood (SUDC).  SUDC occurs in children aged 1-18 years. The cause of death remains unexplained after a thorough investigation. 40 children die without reason every year in England and Wales alone; more young children than to traffic accidents, drowning or fires. The sudden unexplained death of a child is one of the most under-recognised medical tragedies of our time.
