A mum has told how she has to keep her five-year-old son in isolation to stop him from getting infections that could kill him.
Emily Chaney, 36, has been guarding little Jacob all his life after he was born with a rare immune disorder, haemophagocytic lymphohistiocytosis (HLH).
HLH causes the body to react inappropriately to a "trigger" which usually comes from an infection of some kind.
