A mother has released photos of her eight-year-old son in intensive care after he was rushed to hospital with the flu in an attempt to warn other parents about the dangers of the usual virus.
Janine Riley, from Wadebridge in Cornwall, talked about how her son, Henry, went from being an active child who was "fit and healthy" to "struggling to breathe" or walking down a corridor.
The boy was originally diagnosed with influenza after returning home from rugby practice and complaining of abdominal pain.
But his condition quickly deteriorated and left him struggling to breathe and burn.
An ambulance NCE rushed him to hospital where he was diagnosed with the flu – but his condition was so bad that he was transferred to Bristol's pediatric intensive care unit and placed on a ventilator to help with breathing.
But Mrs. Riley, 44, decided to share pictures of her son to warn other parents about how the common disease can develop to dangerous levels.
She said: "He was good one day, played rugby, came home with abdominal pain. We put him to bed with acetaminophen and ibuprofen.

"The next day he was really bad, very hot, struggling with breathing, so we called an ambulance and within minutes he was rushed to hospital.
"A few minutes more in A&E and he was taken to the theater and fell asleep and he was taken to intensive care.
" It was really scary. They couldn't take care of him at our hospital so they transferred him to Bristol pediatric intensive care, where he lay on a ventilator for three days.
"But he was really happy and recovered really well, enough to come back to our local hospital where he st ayed for another two weeks.
"We had lots of physical therapy and got him breathing again. He couldn't get up, he couldn't walk.
"He had gone on a few days from being a fit, healthy eight year boy to not being able to walk along the corridor, it was really sad."
Public Health England (PHE) is increasing the number of children receiving a nasal spray to protect against the virus.
All school children in England are currently eligible for a free influenza vaccination against the NHS.
Dr Julie Yates, director of screening and immunization at Public Health England South West, said influenza can be "life-threatening."
Dr. Yates said: "We are so happy that year 6 children are now eligible for influenza vaccine which means that all children in primary school can now get this vaccination at school.
It can have serious complications and can be life threatening. At least it can turn you off feet for several days.
"This means absence from school for children and free work for parents, not to mention the possibility of spreading the error in families, especially in the elderly more vulnerable amhället. "
