Aubrey Anderson, a five-year-old from Sterling, Kansas, has been hospitalized with hemolytic uremic syndrome, secondary to E. coli infection. Doctors believe she could remain hospitalized for 3-6 weeks.

Public health officials have not yet been able to determine the source of Aubrey’s illness, unlike in the case of Courtney Hansen, an eight-year-old from Ellsworth, Wisconsin, who was recently released from the hospital after a five-week stay while she was treated for HUS.

In Courtney’s case, the Pierce County Herald reported that she and her younger twin sisters all became ill with E. coli infections after eating wind-fall apples.

Benefits are being planned to raise money for medical expenses.
