A misplaced breathing tube contributed to the death of a 13-year-old boy who became the UK's first known child victim of COVID, a coroner has found.
Ismail Mohamed Abdulwahab, of Brixton, southwest London, died of acute respiratory distress syndrome (ARDS), caused by COVID-19 pneumonia on 30 March 2020.
He died at King's College Hospital in London three days after testing positive for the virus.
Hours before his death, an endotracheal tube (ET) - which helps patients breathe - was found to be in the wrong position and a decision was made by a consultant in paediatric intensive care to leave it and monitor him.
He suffered a cardiac arrest before he died.
Senior Coroner Andrew Harris said: "I am satisfied that he (Ismail) would not have died when he did were it not for the tube misplacement."
He said the tube becoming displaced was "the trigger" that led to Ismail's "unexpected" cardiac arrest.
Mr Harris said "misplaced ET" and "high BMI" should be recorded under ARDS, and COVID-19 pneumonia on Ismail's death certificate.
However, he made it clear that although the tube's positioning contributed to Ismail's death, he did not find that the boy would not have died at another time had there been no misplacement.
He died from "complications of necessary medical treatment for a natural disease".
Ismail's elder sister said her brother first fell ill on 23 March 2020.
He was admitted to hospital on 26 March after experiencing fever, coughing, shortness of breath, vomiting and diarrhoea.
The next day he was put into intensive care and tested positive for COVID.
Ismail's family were not able to be with him in intensive care because of hospital policies at the time.
Seven days before his death, Boris Johnson announced the first national lockdown in the UK.
The teenager's elder sister previously described her brother as a "kind and genuine soul".
His family were also unable to attend his funeral as they were self-isolating after some of his siblings displayed COVID symptoms.
Matt Hancock, who was the health secretary and the father of a 13-year-old child himself, previously said Ismail dying without a parent at his bedside "made me weep".
In April 2020, four people wearing protective clothing and face masks lowered his coffin into a southeast London grave.
