Mia also had rashes on her arms and legs and blue lips and complained she was hot but was cold to touch.
Katie and Soron, who also have a 12-year-old son, Beau, called an ambulance and paramedics rushed her to hospital where she was given intravenous fluids and antibiotics.
However, she went into suspected septic shock and suffered a cardiac arrest around 15 minutes after arriving.
Medics tried to resuscitate her but Mia died around 20 minutes later. Her cause of death was given as sepsis caused by Group A Strep infection.
Katie, a self-employed hairdresser, said: ‘Our world and hearts broke forever when our beautiful daughter was snatched away from us.

‘Mia had been taken to the doctors twice to be told her symptoms were viral. Around 15 hours later she died of sepsis.
‘The unbelievable and unbearable pain we feel is unexplainable and unimaginable.
‘Our beautiful healthy girl was the happiest, brightest, most loving and caring girl who smiled, danced, brought joy and love to everyone she met.
‘She brought so much laughter and fun.’
Following their daughter’s death in December 2022, Soron and Katie have instructed expert medical negligence lawyers to investigate her care.

They, along with friends and well-wishers, have also raised more than £40,000 for charity in Mia’s memory through fundraising events, including sponsored runs and local business donations.
£16,000 of this has been donated to the charity UK Sepsis Trust.
Soron and Katie have also set up their own charitable organisation aiM – an anagram of Mia’s name – to raise awareness of sepsis and support other bereaved families.
This summer they organised a family and music festival called aiM Festival and raised more then £21,000. They hope to stage the event next year as well.

Soron, a 39-year-old engineering teacher, said: ‘A lot of people may have heard of sepsis but it’s only after what happened to Mia that we realise just how dangerous it is.
‘We started researching and reading more about it and it was clear to us that Mia had red flag symptoms of sepsis but we weren’t told to take her to hospital.
‘It’s the sad reality that there are families out there, like us, that are suffering from loss due to sepsis, this has to change.
‘We need to educate the public and health professionals to identify the signs of sepsis and ask the question ‘could it be sepsis?’.
Katie said they will never get over the pain of losing Mia.
Soron, a 39-year-old engineering teacher, said: ‘A lot of people may have heard of sepsis but it’s only after what happened to Mia that we realise just how dangerous it is.
