Children in China infected with novel coronavirus showed less severe symptoms than adults, though infants and toddlers were vulnerable to moderate and severe infection, according to a new study published online in the medical journal Pediatrics on Monday.
The study examined 731 confirmed and 1,412 suspected cases of COVID-19 in children. Out of the combined 2,143 cases, one child, a 14-year-old boy, died and nearly 6% of cases were severe, compared with 18.5% of adults experiencing severe symptoms.
Young children, particularly infants, were vulnerable to COVID-19 infection, the authors of the study said. Nearly 11% of cases were severe and critical for infants less than 1 year old.
More than 90% of all pediatric patients were asymptomatic, showing mild or common forms of illness. About 13% of patients who tested positive for the virus did not show symptoms of illness.
Researchers remain unsure why children with COVID-19 were not as ill as adults.
