Children under the age of five have between 10 to 100 times greater levels of genetic material of the coronavirus in their noses compared to older children and adults, a study in JAMA Pediatrics said Thursday.
The patients were divided in three groups: 46 children younger than five-years-old, 51 children aged five to 17 years, and 48 adults aged 18 to 65 years.
One recent study in South Korea found children aged 10 to 19 transmitted COVID-19 within households as much as adults, but children under nine transmitted the virus at lower rates.
