(CNN)Severe illness and death remain rare in children with Covid-19, a new study suggests, while disparities do appear in kids who may require critical care or suffer complications.
'Reassuring' study finds children have small risk of death and severe illness from coronavirus
Pediatricians described the findings as reassuring as children accounted for fewer than 1% of some coronavirus cases in England, Wales and Scotland; and only 1% of those children died, the researchers reported.
The researchers -- from various UK institutions -- analyzed data on 651 Covid-19 patients under the age of 19 who were admitted to 138 hospitals across England, Scotland and Wales between January and July. These young patients accounted for 0.9% of all patients in those hospitals at the time, the researchers noted.
Six of those young patients -- or 1% -- died in hospital. In comparison, 27% of Covid-19 patients of all ages died over the same time period, the researchers noted in their study, published in the British medical journal BMJ on Thursday.
Overall, 18% of the young patients needed critical care and "Black ethnicity was significantly associated with admission to critical care," the researchers noted.
