A seven-year-old girl has died of a suspected flu just days before Christmas .
Isabella Lagronova collapsed at her home on Sunday, a few days after celebrating Christmas jumper day at her school.
She was taken to the Royal Victoria Hospital in Newcastle but despite best efforts of medical staff she was declared 'brain dead'.
She died in her mum Zdena's arms days later.
Her devastated family paid a moving tribute to the youngster who was looking forward to celebrating Christmas.
Mum Zdena told the Chronicle : "On Friday, she went to school. It was Christmas Jumper Day and she was excited."
The next day the schoolgirl started vomiting and coughing. By Sunday, she had a high fever and collapsed.
Her grandad gave her first aid and an ambulance was called to take her to hospital.
"She was put on machines," said Zdena. "On Tuesday morning, they did a last test and said she was brain dead."
At 2.26pm that day, Isabella died in her mum's arms. Zdena and her sister were by the youngster's side as hospital staff switched off her machines.
The family were told the girl had influenza B.
A heartbroken Zdena paid tribute to her wonderful daughter, who loved singing and dancing, and was looking for to Christmas.
"My heart is dead. She was my Twinkle Twinkle Little Star," she added.
The youngster's death has rocked the community and within days more than £5,700 has been donated to a JustGiving fundraising page to help the family at this difficult time.
Friend Debbie Craig, who set up the page, said: "Everybody has been touched by what happened.
"Isabella was a lovely little girl. Her mum was never away from her, they did everything together. Zdena never went anywhere without her. Her daughter was her life.
"Zdena has thanked all the people who have made donations to the page and says it means a lot to them."
