That’s 5% of the Welsh population are rare exceptions
Wales’ first ever plan to tackle rare diseases has been launched and it sets out the WAG’s expectations of the NHS in Wales to treat rare diseases for people of all ages, wherever they live & whatever their circumstances.  A rare disease is defined as a life-threatening or chronically debilitating disease, which affects five people or less per 10,000 and can range from life-limiting illnesses to manageable conditions, which do not affect daily living.  There are around 150,000 people affected by such diseases in Wales.
