Q31.D
Hemolytic-uremic syndrome (or haemolytic-uraemic syndrome, abbreviated HUS) is a disease characterized by hemolytic anemia, acute renal failure (uremia) and a low platelet count (thrombocytopenia). It predominantly but not exclusively affects children. Most cases are preceded by an episode of diarrhea caused by E. coli O157:H7, which is acquired as a foodborne illness
