ENCA is a non-profit organization that works to support associations for juvenile idiopathic arthritis (JIA) across Europe. ENCA gathers information from medical associations and doctors, shares it with associations worldwide, and disseminates medical knowledge to parents and healthcare systems. ENCA also helps fund research projects and works closely with PRES and PRINTO on conferences and studies. Through collaboration, ENCA has increased knowledge of JIA and created a network for organizations and families to access expertise.
