When 11-year-old Nupur Mate complained that she had a headache, her mother took her temperature and monitored her symptoms.

It seemed like the common cold, or maybe the flu, but when her fever hit 102.2 F and she couldn't stop shivering, her parents rushed her to the emergency room at a nearby hospital in Mississauga, Ontario, Canada.

Doctors took one look a the little girl and told her parents to take her home, it was the flu and she could recover from it at home. But Nupur didn't get better, so her parents took her back a second time. Again, doctors told them to take her home, it was definitely the flu.

But they were wrong.

By the third visit to the hospital, Nupur's heart stopped and she had to be resuscitated. The young girl then underwent surgery to amputate two limbs: her left arm and right leg. Now, she is surviving on dialysis at the Hospital for Sick Children in Toronto.

Her diagnosis? A serious bacterial infection caused by streptococcus A.

Now the family is questioning why doctors had turned away their daughter twice. "One day, fever "” OK. But three days, plus the pain ... you don't just say 'oh, it's flu,'" her mother Sunita told CBC Toronto.

The bacterial infection was rapidly attacking their daughter's body. Nupur's mother watched helplessly in the ambulance beside her daughter side as the girl's heart rate plummeted.

"I heard a nurse say, 'She's dead,' then everyone, doctors and nurses, rushed over."

Doctors told her parents that they would have to amputate the young girl's limbs to stop the spread of the infection from spreading further throughout her body.

According to an interview with Dr. Alison McGeer, it is quite rare that this infection would progress the way it did in Nupur.

CBC reports that it's a one-in-a-million instance for strep A to cause toxic shock as it did in this case. There is also no vaccine to prevent a streptococcus A infection "” and no way to tell who can fight the infection and who cannot.

Her spirit endures:

Although this horrible infection has nearly taken her life, Nupur's spirit and will to live is still strong.

The young girl will remain in Sick Kids on dialysis until her kidneys stabilize and then she has a long road ahead of rehabilitation and prosthetics.

"It attacked everything in her body but her spirit," her mother said.
