Via Austria's derStandard.at: A quarter of all patients suffering from HUS -suffer consequences. Excerpt from a computer translation, with my editing:
Those who survive HUS are not automatically healthy again: "It's not like a flu that is easily got over," says Reinhard Würzner of the University Hospital of Innsbruck.
The hemolytic-uremic syndrome, HUS for short, is the worst complication that can occur during infection with EHEC bacteria. About a quarter of all patients suffer this long-term sequelae.
Normally up to three quarters of all HUS patients are children and only a quarter adults; but in the current outbreak the proportions are just the opposite. But because children have better recovery ability than adults, this time more HUS cases could suffer permanent damage, Würzner fears.
The most common long-term consequences for HUS patients are renal damage. Although patients do not always need dialysis, kidney function can be reduced permanently.
Another outcome can be brain damage that can lead to symptoms similar symptoms to a stroke: stuttering, trembling, and epileptic seizures.
