The season at school is almost up to us, but instead of celebrating an early quiet house or buying school supplies, parents prefer to panic instead about whether their children will be in the classroom and safe from the coronavirus. And of course, if they are back in school, the question is whether they will bring the virus home or not. Now a new study provides a surprising look at these issues. A study at the Medical Faculty of Northwestern University in Feinberg found that young children in particular have much more coronavirus than adults. In fact, the research found that “100 times more SARS-CoV-2 in the upper respiratory tract of young children”; up to 5 years.
New study published in 2006 JAMA Pediatrics, followed 145 COVID-19 patients with mild to moderate disease within one week of the onset of symptoms. The researchers compared three age groups: young children under 5, children aged 5 to 17, and adults aged 18 to 65. Although they found similar amounts of coronavirus present in older children and adults, in children less than 5 years of age, they found 10 to 100 times more airway particles.
The research was conducted Taylor Heald-Sargent, MD, a specialist in pediatric infectious diseases at Ann Children’s Hospital and Robert H. Lurie in Chicago. In the Heald-Sargent report and her team, they note that children often cause the spread of respiratory and gastrointestinal diseases – and COVID-19 may not be different.
“It certainly proves that children have similar and perhaps even higher levels of the virus than adults,” Heald-Sargent said. The New York Times“It wouldn’t be surprising if they could get rid of it [the virus]”And spread it to others. (Viral release indicates how long someone releases contaminated particles. “Evidence suggests that a new coronavirus is most severe when symptoms are worse and viral shedding is high,” notes WebMD.)
The research states that the termination of schools at the beginning of the pandemic probably “thwarted an extensive investigation of schools as a source of transmission in the community.” In other words, we still don’t know if schools are COVID-19 superspreaders, because we closed them in the first weeks after the outbreak.
“The situation at school is so complicated – there are many nuances besides science,” said Heald-Sargent. times.

A recent study from South Korea – published in the CDC magazine Emerging infectious diseases—looked at whether the children spread COVID-19 or not. Researchers targeted 5,700 people who reported symptoms of the coronavirus between January 20 and March 27, the time South Korea closed schools. The findings suggest that people aged 10 to 19 are most likely to spread the coronavirus in their homes.
“We found COVID-19 in 11.8% of household contacts; the rate of contact between children was higher than that of adults,” the researchers said. Approximately 19 percent of those who shared a home with sick patients in this age group from 10 to 19 years also contracted with COVID-19. Children under the age of 10 were least likely to spread the disease (about 5 percent of their contacts became ill). Thus, there is evidence that children of a certain age are more infectious.
As for the new study, said Heald-Sargent times. “One of them is the fact that we can’t assume that just because children don’t get sick or not very ill, they don’t have a virus.” And for more information on children and COVID projects, see the 8 most likely ways children can spread the code.
