Lawyers for the unnamed girl said her parents took her to Frimley Park Hospital in Surrey, southeast England, with a high fever, drowsiness, and vomiting, Metro reported. These symptoms are “red flags for meningitis and sepsis,” according to the BBC News, but doctors sent her home with paracetamol, or acetaminophen.

Her parents returned to the hospital when her condition worsened, and doctors diagnosed her with meningococcal sepsis. She later experienced multi-organ failure.

The severity of her sepsis later led to her needing the quadruple-limb amputations, Elizabeth-Anne Gumbel KC, who is representing the family, said, the BBC reported. The girl had above-knee amputations of both legs, and above-elbow amputations of her arms.

Her family argued that if doctors had immediately treated her with antibiotics, she would not have been so ill and might have kept her limbs.
