HUS caused by E.Coli, the child will have had a preceding episode of diarrhoea, which is usually bloody. For this reason it is sometimes call diarrhoea positive (D+) HUS. When HUS is caused by the Pneumococcal bug, the child may have had a chest infection.
Symptoms include paleness, tiredness and weakness - which are all indicative of anaemia. A child may pass less urine or stop passing urine completely. This means that the kidneys are unable to remove excess salt and water from the body, which can lead to swollen face, tummy, hands or feet (oedema), and hypertension (raised blood pressure). Other organ systems may be affected and there may be signs of neurological involvement.
