It has been clear from the start of the Covid-19 crisis – from Wuhan’s experience, before cases were confirmed in Britain – that it was a disease with relatively little impact on children. A broad study led by Liverpool University and published in the British Medical Journal today confirms that – and sheds a lot more light on how Covid-19 affects children.
The study looks at data from 260 hospitals in England, Scotland and Wales, to which 69,516 patients were admitted with Covid symptoms between 17 January and 3 July. Of these, 651 were aged under 19 and 225 were aged under 12 months. Serious underlying medical conditions were present in 42 per cent of the children.
Most were successfully treated on hospital wards but 116 went on to be admitted to critical care and 58 ended up on mechanical ventilation. In 52 cases, the patients were judged to be suffering from Multi-System Inflammatory Syndrome associated with Covid-19 (MIS-C), a condition similar to Kawasaki disease and Toxic Shock Syndrome, that was first identified in London hospitals in March. Six children went on to die. Three were aged under 28 days, had been born very premature and had complex congenital anomalies and bacterial sepsis.
The other three who died were in the 15-18 age bracket, two of whom had profound neurodisabilities which compromised their respiratory systems. The other had a suppressed immune system as a result of cancer treatment and was also suffering from bacterial sepsis. No children without a serious comorbidity of an additional illness died, and neither did any child between the ages of 28 days and 15 years. However, the age group 10–14 years was over-represented among those admitted to critical care.
