The study showed that children over 10 years old pass COVID-19 no worse than adults

A new large-scale study conducted in South Korea showed that children over the age of ten years spread the coronavirus at least at the same level as adults, writes The Washington Post.

At the same time, it is noted that children under ten years old are approximately twice less likely to infect others with coronavirus. Presumably, this may be due to the fact that the volume of air exhaled by children is less than in adults. Another hypothesis is that children are shorter and exhale closer to the ground, so the likelihood that adults breathe in infected air is reduced.

At the same time, children 10-19 years old, according to the study, can infect others even more likely than adults. The publication indicates that this may be an error or due to the behavior of children: although older schoolchildren are already equal to adults in growth, their hygiene habits can be like those of young children. In addition, adolescents may be more likely to communicate with peers and, therefore, are more likely to transmit the virus.

For the study, scientists selected 5,706 people whose first symptoms of COVID-19 appeared in the family from January 20 to March 27, and identified 59,073 contacts of these patients. They then tested all those who had contact with the patient in the household, regardless of whether they developed symptoms. Outside the household, only symptomatic contacts were tested.

Interviewed by The Washington Post experts called this study "one of the best research on this issue that we have today."

In the context of the results of the South Korean study, the publication again raises the question of opening schools this fall amid the ongoing pandemic of the coronavirus.
