Children under five years of age have 10 to 100 times the level of genetic content of coronovirus in their noses compared to older children and adults, JAMA Pediatrics Said on Thursday.
Its authors have written that young children may be important drivers of COVID-19 transmission within communities – a suggestion consistent with current prevailing narrative.
The paper has come as US President Donald Trump is pushing for the administration and daycare to reopen to propel the economy forward.
Between March 23 and April 27, researchers performed nasal swab tests on 145 Chicago patients with mild to moderate disease within a week of symptom onset.
The patients were divided into three groups: 46 children under the age of five, 51 children aged five to 17, and 48 adults between 18 and 65 years of age.
Ann & Robert H. The team, led by Taylor Heald-Sergeant of Lurie Children’s Hospital, observed, “100 times higher amounts of SARS-CoV-2 in the upper respiratory tract of young children.”
The authors stated that a recent lab study had shown that the more viral genetic material was present, the more infectious viruses could be grown.
It has also been shown previously that children with high viral weights of respiratory viral virus (RSV) are more likely to spread the disease.
The authors wrote, “Thus, young children may be important drivers of SARS-COV-2 that are widespread in the general population.”
“Behavioral habits of young children and close relationships in school and day care settings create concern for SARS-CoV-2 amplification in this population as public health restrictions are relaxed,” he concluded.
The new findings are in line with the current view among health officials that young children – who, it is well established, are less likely to fall seriously ill with the virus – do not spread it to others either.
However, very little research has been done on this subject so far.
A recent study in South Korea found that COVID-19 is transmitted to children between 10 and 19 years of age in the same way as adults, but lower infection rates in children under nine Happens on.
