Jesse Brown, 11, from Florida died after injuring his ankle which developed on a treadmill into an infection with flesh-eating bacteria, despite being young, healthy, and active. 

The ‘miracle child’ whose parents struggled to conceive wisted his ankle and scratched his leg, which spiraled into a deadly flesh-eating infection after he contracted Strep A.

After the treadmill injury, when his parents saw that Jesse’s leg was covered in dark red and purple splotches, he was immediately admitted to the local ICU.

A doctor diagnosed the 11-year-old with Strep A. The infection caused the young body’s brain to swell.

Despite best efforts of medical professionals, Jesse was unable to be saved.

The family from Winter Park is warning parents about Group A Strep (iGAS) infections which killed their son.

The news comes just as the Centers for Disease Control and Prevention have warned of an increase in iGAS infections.

The rise was spotted across the United States last year and has predominantly impacted children.

The boy’s family spoke to USA Today saying that Jesse sprained his ankle while on the treadmill at a gym on January 16.

Megan Brown, Jesse’s cousin, said that the child woke up six days later on January 22 with ‘a crazy rash.’

She said: ‘His leg was covered in splotchy, purple, and red, almost like bruising.’

Brown described how her cousin’s limbs were cold but he was running a fever.

The family took him to the emergency room where doctors found out that his infection was caused by the Group A Streptococcus bacteria.

The rapid infection which is believed to have festered in his injury began eating away at the boy’s flesh and his brain began to swell.

Brown said: ‘They had to bring him back a couple of times because his heart was doing crazy things.

‘His organs were starting to shut down and they had to intubate him.’

The fifth-grader died on January 27, less than two weeks after sustaining his injury at the gym.

Brown said how the boy’s parents, Betsy and Brad tried to conceive a child for a decade before they were blessed with their ‘miracle child.’

Brown said how her cousin would be delighted with ‘anything with two wheels that could go fast.’

She said that his active and rough lifestyle meant that his family thought little of a small sprain and little cut in the gym.

Speaking to Fox 35, Megan said that the doctors believed the injury made the site weak and therefore is likely that it became the area targeted by the infection.

She added: ‘In my mind, I was in complete disbelief. I was like, he’ll be fine.

‘This could never happen to our family. For this to kill him in just a matter of days was crazy.’

The CDC is investigating the increase in iGAS infections in children across the U.S.

A memorial fund has been set up in honor of Jesse by Lakemont school to raise funds for his family to pay for medical bills and the funeral.
