The life of a schoolchild is full of rough and tumble, bumps and bruises. When a simple scrape was discovered to be the key factor behind US child Rory Staunton's death, however, his parents decided that something needed to be done - and they have saved thousands of lives in his honour.
Rory Staunton - a New Yorker whose parents originally came from County Louth, Ireland - died from sepsis in March 2012.
It all started with a simple game of basketball at school, when 12-year-old Rory dove for the ball and ended up scraping his arm.
The next day, Rory's parents, Orlaith and Ciaran, became worried when he started vomiting and experiencing fever and pain in his leg.
When his condition deteriorated the following day, he was brought to the emergency department of NYU Langone Medical Centre, where blood tests were run. He was eventually diagnosed with a stomach bug, and sent home.
It wasn't long before Rory was back in hospital the next day, however, suffering from organ failure. A closer look at the previous night's blood tests revealed why - his white blood cell count was huge, meaning his body was fighting an infection. Finally, on that Friday night, he was diagnosed with severe septic shock.
As the doctors had failed to catch the infection on time, however, Rory tragically died two days later.
In the wake of their most heartbreaking loss, the Stauntons vowed to work so that no other family would have to experience what they had gone through, and launched the Rory Staunton Foundation.
Under the organisation, the Stauntons petitioned for New York hospitals to introduce a system whereby the signs of sepsis would be spotted, and treatment would be launched quicker.
As a result, New York Governor Andrew Cuomo introduced a set of evidence-based protocols known as Rory's Regulations in January 2013. With all New York hospitals adopting these guidelines for early detection, thousands of lives have been saved.
Indeed, according to a recent report, more people with sepsis are being identified and treated earlier, and fewer of them are dying from the infection.
In a recent feature with the New York Times, Rory's mother Orlaith said: "Rory deserved a chance. Governor Cuomo's work has given every person in New York State a fighting chance, and everyone in the United States deserves that."
