Haemolytic-Uraemic Syndrome (HUS) is a group of blood disorders mainly affecting infants and children. 

HUS is characterised by low red blood cells, AKI, and low platelets. Bloody diarrhoea is a common early symptom - kidney problems and low platelets then occur as the diarrhoea is improving. 

Most cases occur after infectious diarrhoea due to E. coli O157:H7.
