Five-year-old Cathy Kassis was initially diagnosed with a simple cold, but her condition quickly worsened. Her breathing became labored, resembling an asthma attack, yet doctors failed to order bacterial tests. She was only screened for COVID-19 and RSV, both of which came back negative, leaving her without critical antibiotics.

Days later, Cathy’s health deteriorated further. She slipped in and out of consciousness, collapsing in her mother Jasmine’s arms. Her lips turned blue, and her stepfather, Justin, performed CPR for up to 15 minutes before paramedics arrived.

Cathy was airlifted to Westmead Children’s Hospital, where doctors continued CPR for 78 minutes. Although her heart was revived, prolonged oxygen loss caused irreversible brain damage. By the time tests confirmed the infection, her organs were already shutting down.

The true culprit was group A Streptococcus, a common but potentially deadly bacterial infection. Had it been identified earlier, antibiotics could have saved her life. Instead, the misdiagnosis proved fatal.

Justin later reflected on the ordeal, saying accountability for the doctors would come “another day,” but their focus now was ensuring no other parents endured such heartbreak. The family shared their story to raise awareness of the dangers of missed diagnoses.

In the wake of their loss, Cathy’s parents made the decision to donate her organs. On Jersey Day, a national campaign promoting organ donation, Cathy became a real-life hero by saving three other lives.

Her father described her as “a superhero,” emphasizing that even in tragedy, her life carried meaning and left a legacy of compassion.

Though grief remains heavy, the family takes solace in knowing Cathy’s story may inspire awareness and her gift of life will continue through others. Her short life stands as both a warning and a blessing.
